Columbia University professors say they have found the first evidence that two banned pesticides
are harmful to humans. They say their study vindicates a decision by the Environmental
Protection Agency to phase out the chemicals based only on preliminary research on animals.
The Great Lakes Radio Consortium’s Tracy Samilton reports:
Chlorpyrifos and diazinon were once found in over-the-counter products for
in-home pest control. The EPA started to phase out the chemicals four
years ago, after preliminary research showed the chemicals could be
harmful. The new study tracked a group of pregnant women in New York
before, during and after the ban. It found that women with the highest
concentration of the pesticides in their blood had smaller and shorter
babies than those with less exposure. Robin Whyatt is with Columbia’s
Mailman School of Public Health. She led the study. She says there’s no
question the research vindicates the EPA’s decision.
“It certainly supports that that was a good regulatory decision and this also shows that regulation
works.”
While Whyatt says the ban was good policy, she says more studies should be
done to confirm her results. Chlorpyrifos and diazinon are still widely
used in agriculture. Some environmental groups say the chemicals should
also be phased out there.
