But DuPont, the US-based chemical giant that manufactures Teflon, denied exposure to PFO, an acid, which could pose a health risk to the public.

The findings have not resulted in any substantial impact on the company, a DuPont China Beijing office official, said on Friday.

China's product quality watchdog said on Friday that it knows about the incident and has not yet decided whether to test the safety of the non-stick surface for the second time in less than a year. In a &aft report released earlier this week, an advisory board that reviewed the US Environmental Protection Agency's report concluded that PFOA is "likely" to be carcinogenic to humans. The draft was based on tests conducted on animals, and the advisory board mended the US EPA conduct further testing

But a statement released by DuPont on Tuesday said that the company is conducting an employee health study on PFOA and that partial results indicate no association between PFOA exposure and most of the health parameters that were measured. According to Xu Yang, a public relations official with DuPont's Beijing office, about 5 percent of Chinese families use non-stick flying pans compared with 95 percent in the United States.

Last year, the US EPA said it would fine DuPont for failing to report test results regarding PFOA, but the investigation is under way.

China's General Administration of Quality Supervision, Inspection and Quarantine ordered a probe last October, but it detected no PFOA in Teflon cookware.

Farmers will also need less irrigation water and more pesticides because of slightly warmer temperature expected across the continental United States from carbon emissions, the Environmental Protection Agency report said.

In the document, the Bush administration endorsed for the first time the widely held view of scientists that US greenhouse gas emissions will rise significantly over the next two decades due mostly to human activities.

The White House had previously said there was not enough scientific evidence to blame oil refining, power plants and automobile emissions for global warming. The administration has rejected participating in the international Kyoto treaty to reduce greenhouse gases, saying a less costly and effective approach is to encourage voluntary emission cuts by industry.

Although climate change could threaten US barrier islands and mountain meadows, the EPA report said most American farmers had little to worry about.

The US has more than 1 billion acres of farmland, pastures and grazing land.

The rising concentration of carbon dioxide in the soil is beneficial to many crops and should help continue decades of rising crop yields, the report said.

Higher concentrations of carbon dioxide in the soil and slightly warmer temperature should benefit crops such as cotton, corn, soybeans, sorghum, barley, sugar beets and citrus fruits. "In general, northern areas such as the Midwest, West and Pacific Northwest are projected to show large gains in yields, while influences on crop yields in other regions vary more widely," the report said.

For example, some scientific studies cited by the report estimated soybean crop yields could climb by 23 percent to 40 percent, depending on the specific scenario of rainfall and temperature. Orange crop yields could soar by 13 percent to 120 percent. However, corn yields would climb by a more modest 1 percent to 9 percent, the report said.

More carbon also helps the soil hold water and plants grow faster, so that farmers will need less irrigation water, the EPA report said. However, climate change also means many growers will need to use more pesticides, the report said without elaboration.

The EPA acknowledged that scientific analyses have not considered all of the consequences of climate change. on crop pests, diseases and extreme weather. "Agricultural technology is currently undergoing rapid change, the future production technologies and practices seem likely to be able to contain or reduce these impacts," the EPA report said.

Farmers in the Southeast face more uncertainties linked to climate change.

The EPA report said a change in planting dates and genetically altered crop varieties will be important for the Southeast in case summer rainfall declines.

According to a report from the Harvard School of Public Health， many everyday products， including some bug sprays and cleaning fluids， could lead to an increased risk of brain and behavioral disorders in children．The developing brain， the report says， is particularly （36） to the toxic effects of certain chemicals these products may contain， and the damage they cause can be （37） ．

The official policy， however， is still evolving．Health and environmental （38） have long urged U．S．government agencies to （39） the use of some of the 11 chemicals the report cites and called for more studies on their long-term effects．In 2001， for example， the Environmental Protection Agency（40）the type and amount of lead that could be present in paint and soil in homes and child-care （41）， after concerns were raised about lead poisoning．The agency is now （42）the toxic effects of some of the chemicals in the latest report．
