SIGN MERGER AGREEMENT March 15, 1999 from a press release WILMINGTON, Del. and DES MOINES, Iowa -- DuPont (NYSE: DD) and Pioneer Hi-Bred International, Inc. (NYSE: PHB) today announced that they have signed a definitive agreement for a stock and cash merger that will result in DuPont's complete ownership of Pioneer. This transaction is another major step in DuPont's life sciences strategy and will strengthen and accelerate its capability to discover, develop and commercialize a new generation of products across the value chains for food and feed crops, food ingredients, industrial applications and nutrition science. DuPont currently has a 20 percent equity interest in Pioneer. Under the terms of the agreement, Pioneer shareholders will receive $40 per share, with 45 percent of the shares receiving cash and 55 percent of the shares receiving DuPont stock. Pioneer shareholders will have certain rights to elect which form of consideration they receive. The merger is expected to close during the summer of 1999. The total equity value of the transaction is estimated to be approximately $7.7 billion for the 80 percent of Pioneer not currently owned by DuPont. The boards of directors of both companies have approved the transaction. "This transaction will further enhance an already outstanding technology platform and marketing capability, while giving us greater ability to speed new products to market and deliver value across the agriculture and nutrition industries," said Charles O. Holliday, Jr., DuPont chairman and chief executive officer. "Our excellent relationship with Pioneer has grown even stronger during the last 18 months, enabling us to create further synergies by totally integrating DuPont's biology, chemistry and genomics with Pioneer's leading market position and research and development capabilities. The end result should be significantly increased shareholder value." Holliday added, "Both companies are customer focused with compatible cultures and values. By bringing together DuPont's ag businesses and Pioneer's seed business, we are creating an agricultural enterprise with $5 billion in annual sales, which will be focused on growth." "Crop genetics offers tremendous potential for meeting the needs of farmers, agriculture and consumers around the world," said Charles S. Johnson, who will continue to lead Pioneer as chairman, president and chief executive officer. "Bringing the talents and resources of our two companies more closely together will ensure we deliver that potential to the market and do it quickly." The transaction will increase DuPont's ability to create output trait offerings based on its own products or on complementary licensed products. It also will increase the speed to market of these products and will strengthen DuPont's custom offering to food companies. Longer range, DuPont's and Pioneer's combined R&D capabilities in biotechnology will create a stronger scientific platform on which to build biomaterials opportunities. Pioneer is the world's largest seed company, the most recognized seed brand in the world, and a leader in North America and other key markets. Its strength rests on the quality of its proprietary germ plasm, as well as a highly respected brand franchise and integrated product and distribution systems. Pioneer introduced 37 new corn hybrids in 1998 and has introduced 60 new hybrids this year, including high-oil, herbicide and insect-resistant products. As a wholly owned subsidiary of DuPont, Pioneer will continue to do business under the Pioneer name and will remain headquartered in Des Moines, Iowa. It has 5,000 employees worldwide. In the year 2000, the first full year of combined operations, DuPont expects dilution in cash earnings per share of about 1 percent. Fully diluted earnings per share will be reduced by about 7 percent. Last week DuPont announced two strategic efforts to aggressively and rapidly build its life sciences portfolio. First, the company said that it is actively seeking alliances with other strong partners in the pharmaceuticals industry to bring DuPont Pharmaceuticals to critical mass through strategic alliances. Additionally, the company said its board has authorized actions toward the creation and issuance of a "tracking" stock for its life sciences businesses to give DuPont the financial flexibility to more advantageously participate in industry consolidation trends and expand the portfolio. In September 1997, DuPont and Pioneer formed a research alliance and in January 1998, a separate joint venture companyQOptimum Quality Grains, L.L.C. DuPont also invested $1.7 billion in Pioneer to acquire a 20 percent equity interest. DuPont's total investment, including the value of today's transaction, will be approximately $9.4 billion. It currently holds two of the 14 seats on Pioneer's board of directors. Credit Suisse First Boston and Salomon Smith Barney acted as financial advisors to DuPont and Lazard Freres & Co. LLC acted as financial advisor to Pioneer. Skadden, Arps, Slate, Meagher, & Flom LLP acted as legal counsel for DuPont and Fried, Frank, Harris, Shriver, and Jacobson acted as legal counsel for Pioneer. Pioneer Hi-Bred International, Inc. (NYSE: PHB) is the world's leading supplier of agricultural genetics and is the leading developer and integrator of agricultural technology. Headquartered in Des Moines, Iowa, Pioneer develops, produces, and markets a full line of seeds, forage and grain additives and services to grain and livestock producers, grain processors and other customers worldwide. Founded in 1802, DuPont is a global science and technology-based company. DuPont serves worldwide markets including food and nutrition; health care; agriculture; fashion and apparel; home and construction; electronics; and transportation. The company operates in more than 70 countries and has 92,000 employees. DUPONT BUYS SEED FIRM PIONEER March 15, 1999 Reuters/ UPI/ Dow Jones News/ WILMINGTON, Del. -- Wire coverage of the proposed merger notes that the deal is valued at $7.7 billion and gives Dupont the remaining 80 percent of Pioneer that it does not already own. DuPont had purchased a 20 percent stake in Pioneer in 1997. Pioneer shares rose $9.19 in New York Stock Exchange trading Friday to close at $34.31. DuPont shares closed at $57.75. The agreement, which is subject to regulatory approvals, represents an 80% premium above where Pioneer shares were trading early last week, before speculation about a possible DuPont bid ignited the price of Pioneer stock. DuPont's total investment in Pioneer, including the latest transaction, will be about $9.4 billion. Pioneer will keep its headquarters in Des Moines, Iowa, and will be a wholly owned subsidiary of DuPont. Charles Johnson will continue as Pioneer's chairman, president and chief executive. The Dow Jones story was cited as saying seeds are important to DuPont because they connect biotech labs to farmers; they are the delivery mechanism for the genes DuPont scientists are manipulating. Pioneer is the biggest biotech bridge around: It controls 42% of the North American market for seed to grow hybrid corn, the biggest U.S. crop, and it controls 16% of the seed used to grow soybeans, the second-biggest U.S. crop. Before this latest move, DuPont had spent about $6 billion over the past two years to build a "life-sciences" business that will use biotechnology to develop new crops and drugs. The pieces DuPont has acquired so far include a pharmaceutical operation, a crop processor and the 20% Pioneer stake in 1997. To keep its war chest for acquisitions brimming, DuPont Chief Executive Officer Charles O. Holliday has raised funds by shedding the company's Conoco Inc. oil unit and last week unveiled plans to issue a new stock that will track its life-sciences business. Pioneer's agreement to be acquired represents a big cultural change for the 73-year-old company, which was founded by one-time U.S. Vice President Henry A. Wallace to exploit that era's revolution in agricultural genetics hybridization, a breeding technique that greatly increased the productivity of crops such as corn. Pioneer management and descendants of the founding families had long professed their desire to keep the company independent. Indeed, DuPont's original investment in Pioneer came attached with a 16-year agreement that prevented DuPont from buying more without Pioneer's approval. But Pioneer had grown increasingly uneasy about Monsanto's attempts to attract the eye of DuPont. Monsanto is looking for a like-minded merger partner because the debts piled up from an $8 billion biotechnology buying spree is making it hard for Monsanto to go it alone. Industry officials were cited as saying Pioneer executives couldn't afford to see DuPont run off with someone else. That would deny Pioneer access to valuable DuPont genes as well as DuPont's deep pockets.

THREE-YEAR FREEZE ON `FRANKENSTEIN' FOOD CROPS March 15, 1999 PA News A temporary halt to the growing of genetically modified crops appeared closer today after U.K. ministers welcomed plans for a three-year voluntary ban on new plantings of so-called Frankenstein foods. Science Minister Lord SainsburyQalready embroiled in controversy over his links with the GM industryQwas cited as backing plans emerging from the industry for a three-year freeze on new plantations. Such a move would enable the Government to maintain its line that the current safety regime is sufficient, while in practice bowing to the rising fears of consumer groups and some scientists. Lord Sainsbury was quoted as saying, "Obviously the prime requirement is safety and the impact on the environment. If this voluntary arrangement gives even more time before commercial planting, so there's more time to assess the environmental impact, that has to be good, I think." Downing Street last night rejected claims of a "secret deal" between ministers and the industry, saying: "Any ban would be a matter for the companies themselves." Tony Blair has rejected calls for a three-year ban to enable further research to be done into the possible health impact of GM foods. His stance is in spite of a call from the Government's wildlife watchdog English Nature, for just such a ban. SECRET DEAL WILL BAN GM CROPS UNTIL 2002 March 14, 1999 The UK Independent Marie Woolf, Political Correspondent Genetically modified crops are to be banned for three years under a landmark deal being secretly negotiated between the Government and biotechnology companies. After weeks of confidential talks, ministers are poised to announce a breakthrough. Seed companies will agree to a voluntary freeze on growing GM crops in Britain until at least the year 2002. The deal, expected to be announced within the next three weeks, will mark a victory for campaigners, including the Independent on Sunday, who have called on the Government to delay planting GM crops in Britain until there have been more tests on their environmental effects. The new freeze will allow scientists to examine the effect of growing GM crops on other plants, birds and animals. Government sources say that Prime Minister Tony Blair, who believes in the benefits of GM crops and has backed them publicly, is in favour of a freeze if it is agreed voluntarily by the agro-chemical companies. "This is a matter for the industry," said an aide to the Prime Minister. Agriculture and environment ministers have also backed the negotiations between senior civil servants and companies such as Novartis, Zeneca and Monsanto. Ministers have been kept closely informed of progress in the talks, which began six weeks ago. The Government, worried by the backlash against GM food demonstrated in an NOP opinion poll in the Independent on Sunday showing widespread consumer concern, is keen to be seen to be taking action on the issue but believes that the biotechnology industry must take the decision itself. It has ruled out banning the commercial planting of GM crops for fear of provoking a further trade row with the US, which has considerable commercial interests in the new technology. Last year, ministers negotiated a one-year moratorium on planting GM crops commercially in the UK, but this will run out in 2000. Government sources close to the negotiations said that biotechnology companies such as Novartis, which has backed consumer calls for clearer labelling of GM food sold in UK shops, have been "helpful". But Monsanto, the American agro-chemical giant most closely associated with genetic engineering, is said by government sources to be "dragging its feet". The industry body representing biotechnology companies and plant breeders believes that "any delay on the commercial production of GM crops in the UK would be unscientific and unjustified". A possible shortage of GM seed may be one of the reasons the agro-chemical companies will agree to the extended moratorium. English Nature, the Government's official adviser on wildlife, has called for a freeze on commercially growing GM Crops for three years until more data is available. GOVERNMENT UNDER RENEWED PRESSURE TO BAN GM CROPS March 15, 1999 PA News Chris Moncrieff, PA News The UK Government is facing renewed calls for a moratorium on genetically modified food after admissions that the protection of the environment from GM crops was insufficient, the story says. Liberal Democrat environment spokesman Norman Baker demanded the move after Countryside Minister Michael Meacher said in a written Commons reply ministers had been active in their support for a revision of the relevant EU directive to ensure full protection for human health and the environment. According to Mr Meacher, the European Commission wants the directive amended and strengthened on environmental risk assessment, monitoring and better labelling requirements. Mr Baker, MP for Lewes, said afterwards: "The Government has today admitted that the protection of the environment from GM crops is insufficient and that we need to have an urgent review of the directive. The Government cannot argue there is a threat to the environment and then do nothing about it." The story continues by saying that Junior agriculture minister Lord Donoughue disclosed regulating the commercial production of GM food would cost the taxpayer 5 million this year, including 3.7 million on research. He also said, in a Lords written reply, the spending would "underpin the regulatory framework". Donoughue added that 74 people were working on policy development, research co-ordination and regulatory functions related to GM food. M&S BANS GM FOOD PRODUCTS AFTER CUSTOMER CONCERNS March 15, 1999 PA News Alison Little and Dominic Hayes, PA News Marks and Spencer was cited as announcing the removal today of all genetically modified foods from its shelves, as a temporary halt to the growing of GM crops appeared closer. The UK Government is reportedly insisting that there has been no "secret deal" with industry to secure a three-year ban on new plantings of GM crops. A Marks and Spencer spokesman was quoted as saying, "Although we believe there is a place for genetic modification, customers are concerned about the speed at which these developments are being pushed through." According to the authors, M&S will continue to monitor developments in GM technology "and will consider any opportunities which bring direct benefit to our customers". The company has set up a customer helpline on the issue. The number is: 0800 389 4367. Pete Riley, of Friends of the Earth, welcomed the decision: "This is excellent news and an important victory for consumer power. We congratulate M&S for having the courage to listen to the public mood and ban GM food. It will now be impossible for stores like Sainsbury's and Tesco to continue to ignore their customers on this vital issue." Environment Minister Michael Meacher conceded its tone might appear to have modified, and told BBC Radio 4's The World at One: "There is no secret deal between the Government and the industry. We have always said that before the full-scale commercialised growing of GM crops takes place in this country we would need to be sure that they don't harm the environment." The story goes on to say the Government was negotiating with biotechnology companies involved in GM crops on how "farm scale trials should be conducted". As well, Adrian Bebb, food campaigner for Friends of the Earth, believes a three-year ban would not allow proper assessment, and that it should be five years. Bebb added: "We are also calling on the Government to massively reduce the number of trial sites taking place throughout the country. There were more than 300 last year. We think many of the trial sites were for commercial purposes, looking at areas such as yields." Liberal Democrat spokesman Norman Baker was also quoted: "If this moratorium is confirmed it will be welcome, but the small print of any voluntary agreement must be tight enough to prevent abuse by the companies." GERMANY TO RELY ON SCIENCE FOR GENE CROP APPROVAL March 15, 1999 Reuters HAMBURG -- Today, Germany's agriculture ministry was cited as saying the licencing of genetically modified (GM) crops for plantings in the European Union was entirely up to the scientific and legal bodies in place, adding that, "Detailed assessment of new GM crops under the existing law is paramount in order to protect consumers and reach fail safe decisions on their safety. This takes priority over any premature approvals to the benefit of the industry or importers." But, the story says, the government has reportedly seen no reason to change the obligatory procedure for any GM crop licencing -- certification of safety by the Berlin-based Robert-Koch-Institute (RKI) and approval by the licencing authority Bundessortenamt (BSA) in Hanover. A spokesman at life sciences company AgrEvo in Frankfurt was cited as saying that even without political interference in Britain, EU biotechnology firms had been exposed to a "de facto moratorium for the last 12 months." The EU licencing system for new GM crops had more or less collapsed, with France blocking progress and Britain opposing products with genes modified to resist antibiotics. The story goes on to cite a spokeswoman at the German headquarters of environmental lobby Greenpeace: Germany's public was hostile to GM foods and authorities would be well advised to join those in other EU countries in their opposition to GM crop approval. Christiane Toussaint, scientific adviser at food industry institute BLL in Bonn, said the GM crop debate in Germany would be carried out more rationally than in other EU states because industry and consumer groups had been discussing this longer. She was cited as saying: "We have a head start in dealing with public concerns," she said. "But this does not make GM crop licencing any easier once the discussion becomes purely political." FRENCH ENVIRONMENTALISTS WANT LONGER GENE CROP BAN March 15, 1999 Reuters PARIS -- France is also calling for a longer, broader moratorium so wider tests on genetically engineered crops may be carried out. A campaigner, Etienne Vernet at Ecoropa said: "This is a sign of encouragement which should push the French government to reconsider the risks from gene modified foods," "We want a moratorium on all types of GM food for three to five years so we can do more tests. If Britain did impose a three year freeze, France should do the same thing." Greenpeace France Director Bruno Rebelle also backed a freeze on GM crops until at least 2002 and more rigorous tests. According to the story, France imposed a two-year freeze on genetically engineered oilseed varieties last July after concerns the modifications could be transmitted to other crops. In December the high court upheld a freeze on three strains of gene-modified maize seeds while the case goes to the European court of justice. The story continues by citing GM campaign coordinator, Stephen Kerckhove at environmental group Agir pour l'Environment, as saying: "Lots of countries are starting to challenge (GM foods). The consumer is starting to bring more and more to this debate." Nobody was available for comment at France's environment ministry, but an agriculture ministry spokeswoman said a freeze in Britain would not influence France's position on GM crops, the story says. But the environmentalists, who work closely with counterparts in other European countries, said opposition to GM foods was growing across Europe and urged environment ministers to broach the debate together. MONSANTO - HANDLED WITH CARE? OR, CARE - HANDLED BY MONSANTO? MAJOR U.S. RELIEF AGENCY HOLDS TALKS WITH TROUBLED AGBIOTECH MULTINATIONAL - WHO'S HELPING WHO? March 9, 1999 Rural Advancement Foundation International (RAFI) News Release http://www.rafi.org CARE, the high-profile U.S. food aid non-profit, is holding talks today with Monsanto Corporation at the company's world headquarters in St. Louis, Missouri (US). According to information received by RAFI, Monsanto's CEO Robert Shapiro contacted CARE's President, Peter Bell, inviting CARE officials to discuss ways in which Monsanto may be able to use its technologies for the benefit of food security in the South. Whether this is an attempt to resurrect Monsanto's scheme to provide micro-credit ("soft") loans to Third World farmers in order to market its proprietary pesticides and genetically-modified seeds remains to be seen. Monsanto is one of the world's leading Gene Giants - dominant in both crop chemicals and seeds. The company's best known product, Roundup (glyphosate), is the world's top selling herbicide and a multi-billion dollar profit engine for Monsanto. The company's patents on Roundup are expiring, however, and Monsanto is looking for new ways to maintain its market share and to advance sales of its controversial transgenic (genetically-modified) soybean, maize, cotton, and potato varieties. Using genetic engineering, Monsanto has bred seeds that tolerate Roundup spraying. It is estimated that the contentious market strategy has won Monsanto at least 85% of the booming U.S. transgenic seed market, and experts suggest, a similar share of the global transgenic market. * Cash 'n CARE? In June 1998, Monsanto announced that it would develop a special microcredit programme with the Grameen Bank of Bangladesh that would have made it financially feasible for cash-starved farmers to take out loans to buy Monsanto's advanced technology products. The Grameen Bank has won international accolades for its championing of credit programmes to rural women who would not normally be seen as credit-worthy by conventional banks. Within a month of the Monsanto-Grameen announcement, however, the Bangladeshi institution cancelled the deal bowing to intense public pressure within South Asia and around the world. * Once More with Feeling? "At the time, we heard rumours that CARE and possibly some other development aid agencies were discussing similar deals with Monsanto" Pat Mooney, RAFI's executive director says, "but we were told that CARE backed away from the table when Grameen threw in the towel.""Now we are informed that an international team of CARE officials from their New York office, but also from some of their major regional offices, have gone to St. Louis to discuss a major initiative with Monsanto," Mooney adds, "This could be a real problem." GMO's in Every Pot? Last year, more than 27.8 million hectares of farmland around the world was sown to genetically modified crops. Seventy seven percent of this land was sown to transgenic seeds designed to tolerate herbicide spraying. While the biggest market for biotech seed is in the USA and Canada, South countries such as Argentina, Mexico, South Africa, and China have also adopted the controversial seeds. Trials of Monsanto's transgenic seeds in India have led to mass demonstrations and intense debate in the media and in government. Similar debates are underway in Brazil. In Europe, environmentalists, farmers, and consumers have joined together to oppose the use of transgenic seeds. * GMO's Handled by CARE? Blocked in Europe, is Monsanto trying to use well-known aid agencies to win acceptance for its GMOs among farmers and consumers in the South? "Monsanto officials genuinely believe they have products that will solve the problem of food shortages in the next century," Hope Shand of RAFI says. "The company may not be acting cynically. They believe they can make money and solve hunger through GMOs at the same time," Shand explains, "If the meeting with CARE is to use the food aid agency to test and distribute their genetically-altered seeds among poor farmers, both CARE and Monsanto are making a terrible mistake."What exactly the goal is for the St. Louis talks? Are they to establish soft loan programmes tied to Monsanto products, or to use CARE's field offices to facilitate trials of genetically-engineered herbicide-tolerant seeds? "Either way," Pat Mooney concludes, "neither party has the credibility to pull this venture off. CARE will be lambasted for jeopardizing the food security of farmers and Monsanto will be accused of using CARE as 'cheap labour' for its commercial goals. Whatever their intent, this indeed will be the result. I've talked with CARE negotiators in New York and I'm hopeful that they understand the issues and will not let their good name be used to pressure farmers into adopting Monsanto's unsustainable approach to agriculture." CARE Bears? Monsanto is transforming itself from being a traditional chemical company into a dominant player in the Life Industry. In recent years, Monsanto has spent more than $8.5 billion in acquiring seed companies across the world. Many market analyst believe however, that Monsanto has over-extended itself and is now weighed under by a huge debt burden. In the midst of the world's longest running bull market, Monsanto is on some investor's bear lists. Last year, Monsanto announced that it would merge with American Home Products - another chemicals-turned-biotech corporation more than twice Monsanto's size. The deal was eventually called off. Last week, the New York Times reported that Monsanto was holding preliminary discussions with DuPont - a vastly larger multinational now attempting to extricate itself from energy subsidiaries in order to buy into the Life Industry. The message to many investors is that Monsanto is a company in trouble and looking for allies. PESTICIDES MAY HARM BRAIN, STUDY SAYS HEALTH: FETUSES AND YOUNG CHILDREN IN FARM AREAS ARE AT HIGHEST RISK, RESEARCH SUGGESTS, WITH INTELLIGENCE, MOTOR SKILLS AND PERSONALITIES AFFECTED March 15, 1999 The Los Angeles Times MARLA CONE, Times Environmental Writer Wayne Porter, a University of Wisconsin professor of zoology and environmental toxicology, was cited as reporting in a paper published today in the journal Toxicology and Industrial Health that a common mix of insecticide, herbicide and fertilizer found in drinking water altered the thyroid hormones of young mice and changed their aggressivenessQmeasured by attacks on other miceQand suppressed their immune systems. The story says that although a study of mice alone is not overly compelling, the theory is bolstered by recent research on human beings. In tests in the state of Sonora, Mexico, scientists found striking differences in hand-eye coordination and other mental and physical skills when comparing Yaqui Indian preschoolers in an agrarian region with those in adjacent foothills where no pesticides are used. Four- and 5-year-olds living in the farm valley had trouble performing a variety of simple motor skillsQdrawing stick figures, catching a 12-inch ball from almost four yards away and a tennis ball from more than a yard away, and dropping raisins into a bottle cap from a distance of six inches. They also had poorer memory skills and stamina, were more prone to physical aggression and angry outbursts, and were less sociable and creative while playing. The story says that farm and household pest-killers are widely used there, and high levels of multiple pesticides have been found in the cord blood of newborns and the breast milk of mothers in the area. Another study, in rural western Minnesota, found increased birth defects in children conceived during the spring growing season. Most of the new research detects problems in agricultural communitiesQplaces found not just in rural regions but also in more urbanized areas, including Southern California. No one knows yet what it might mean for people who consume small traces of the chemicals in their food. Earlier this month, Consumers Union reported that many fruits and vegetables contain concentrations of pesticides that may be unhealthful for children. The new hormone studies add to a growing body of research from around the world suggesting that dozens of commonly used pesticides and other chemicals mimic the hormones that control sexual and neurological development. Called endocrine disruption, this is arguably the most controversial environmental issue of the past decade. Scientists were cited as saying the study and other recent research support an emerging theory that pesticides may exact a toll on the intelligence, motor skills and personalities of infants, toddlers and preschoolers. Porter's study was quoted as saying, "Data suggest that we may be raising a generation of children with learning disabilities and hyper-aggression." John McCarthy, vice president of a group representing pesticide manufacturers, the American Crop Protection Assn. was quoted as saying, "I'm kind of dubious that low-level exposures to chemicals are raising all kinds of havoc with the endocrine system. The human system has so many protective mechanisms, and our bodies are bombarded with all kinds of things." Still, he said, the industry is highly concerned about the findings suggesting neurological damage, and would like to see a comprehensive review to evaluate all existing studies and figure out what they collectively show, adding, "We ought to be taking a very hard look at it. There's almost a study a week of one type or another, and it's hard to see how it all fits together. We have to take some time to say, 'OK, what does this all mean? Is this something that should require some abrupt change [in pesticides] or fine-tuning or more research?' " The story adds that no one knows how many pesticides out of 77,000 used in the United States might alter sex or thyroid hormones. Questions abound: How do the contaminants disrupt thyroid levels? What does that physically do to the brain? What dose of exposure does it take? Does the human body have some defense mechanism to fend off low levels of hormones? What do mixes of various man-made and natural hormones do to people? Some scientists suspect that the damage is passed from a mother to her unborn child early in the first trimester, before most women even know they are pregnant. Thyroid hormones guide the nerve cells that dictate how the brain of a fetus develops and the number of brain cells created. One theory is that if a mother receives a dose of pesticides during this critical phase, it can interfere with her thyroid levelsQsometimes raising them, sometimes lowering themQirreversibly altering the child's nervous system. How the child's brain circuitry develops determines his or her hand-eye coordination, motor skills and learning ability. Thyroid hormones also can change behaviorQan excess can make people quick to anger, while a low count could have the opposite effect. The hormones also can alter steroids that control aggression and immune systems. Dr. Harley Kornblum, a pediatric neurologist at the UCLA Medical Center was quooted as saying, "Thyroid hormones are important to brain development, and that's been known for a long time," but, the story adds, he and other neurologists say, it's debatable how important the mother's thyroid level is to the fetus, and it's even more uncertain what role environmental contaminants may play. Porter said children up to age 8 who have developing brains and immune systems are "especially vulnerable" to changes in thyroid hormones. The story goes on to note that some scientists remain dubious of the results because the tests on the children were unusual, and are intrinsically subjective and difficult to interpret. Dr. Richard Jackson, director of the National Center for Environmental Health at the federal Centers for Disease Control and Prevention, was quoted as saying his staff was "unimpressed by the scientific rigor" of the work in the report and that although the differences between the two populations of children seem striking, other hidden factors, rather than pesticide exposure, cannot be ruled out. In Porter's 5-year study of mice, the animals drank water containing a mixture of two pesticidesQaldicarb and atrazineQand nitrates from fertilizer. The concentrations ingested by the mice were similar to those found in ground water in many agricultural areas, Porter said. Aldicarb, atrazine and nitrates are the three most abundant agricultural contaminants in the United States, although they do not rank high in use in California. While the mix of the three chemicals altered the mice hormones, each one alone did not. That points out a gaping hole in the federal effort to protect consumersQthe EPA only tests for effects of pesticides individually, not cumulatively. The EPA tests, Porter said, "generate a great deal of false confidence in the safety" of pesticides.
