Obscure Poisonous Pesticide Present in 4 out of 5 Folks Examined

4 in 5 folks might include traces of a doubtlessly harmful pesticide of their urine, a brand new examine warns.

The pesticide in query is chlormequat, an agricultural chemical that has been proven to break reproductive well being and fetal growth in animals and will trigger comparable issues in people, notably youngsters. Nonetheless, the extent of those well being impacts continues to be poorly understood.

Within the U.S., chlormequat can be utilized solely on decorative crops, not meals crops. Nonetheless, since 2018 the Environmental Safety Company has permitted the presence of chlormequat residues on imported oats and different meals.

“Chlormequat is primarily used on grain crops like oats, wheat and barley,” Alexis Temkin, a senior toxicologist on the nonprofit Environmental Working Group (EWG) and lead writer on the examine, informed Newsweek. “[However,] within the U.S. solely imported varieties of those crops are allowed to have chlormequat residues.”

In a latest examine revealed within the Journal of Publicity Science and Environmental Epidemiology, Temkin and her EWG colleagues investigated the prevalence of this chemical—which the EWG has described as “poisonous”—in oat-based meals merchandise in addition to its presence in human urine.

“Testing of oat-based merchandise discovered chlormequat in 92 p.c on nonorganic samples and solely low ranges on one in every of eight natural meals,” Temkin mentioned. “EWG additionally examined 9 wheat-based merchandise and solely discovered chlormequat in two merchandise at low ranges.”

To check for the prevalence of this compound in people, the group took urine samples from 96 people within the U.S. between 2017 and 2023 and examined them for the presence of chlormequat.

“Our findings present that of the folks we examined, 80 p.c of them had been uncovered to chlormequat and that samples collected in 2023 had extra detections and at greater concentrations,” Temkin mentioned.

She went on: “Whereas this was only a pilot examine, and never essentially indicative of the overall inhabitants, on condition that chlormequat is prevalent in in style oat-based merchandise, all these meals are possible a significant supply of publicity for most people.”

Due to the results of this compound on fertility and growth in animal research, the prevalence of chlormequat in human meals and urine “raises alarm bells” and requires additional investigation, Temkin mentioned.

“Understanding these potential dangers is urgently wanted,” she mentioned. The U.S. Division of Agriculture and the Meals and Drug Administration “needs to be testing grains for chlormequat as a part of annual pesticide monitoring,” she added.

“The Environmental Safety Company wants to totally think about the potential dangers to youngsters’s well being from chlormequat publicity and rethink their latest choices to permit chlormequat to be current in youngsters’s meals,” Temkin mentioned.
