Eparejects own findings that a pesticide is harmful
WASHINGTON — The Trump administration has rejected scientific evidence linking the pesticide chlorpyrifos to serious health problems, directly contradicting federal scientists’ conclusions five years ago that it can stunt brain development in children.
The Environmental Protection Agency’s assessment of the pesticide, which is widely used on soybeans, almonds, grapes and other crops, is a fresh victory for chemical-makers and the agricultural industry, as well as the latest in a long list of Trump administration regulatory rollbacks.
The EPA said Tuesday that “despite several years of study, the science addressing neurodevelopmental effects remains unresolved.” However the agency excluded several epidemiological studies, most prominently one from Columbia University.
As a result, the assessmentmay be the first major test of the Trump administration’s intention, often referred to as its “secret science” proposal, to bar or give less weight to scientific studies that can’t or don’t publicly release their underlying data. This would eliminate many studies, because the data often includes confidential medical records of the subjects, scientists have said.
The EPA repeatedly cited a lack of access to rawdata in the studies it rejected, and came to the conclusion that the findings — though they have been backed up by other peer-reviewed studies — were inconclusive.
“This shows that EPA has completely abandoned any commitment to protecting children from this extremely toxic chemical when their own scientists recommended twice to ban it. The science is being overridden by politics,” said Erik D. Olson, senior director for health at thenaturalresources Defense Council.
James Hewitt, a spokesman for the EPA, said in a statement that the agency “remains unable to verify the reported findings” of the Columbia study.
Several states, including California, New York and Hawaii, already have enacted bans of varying strictness. Corteva, the world’s largest manufacturer of chlorpyrifos, has said it will stop producing the chemical by the end of this year.
