"Extreme heat makes pesticides evaporate—and keeps them airborne."
"As this year’s temperatures continue to break records, farmworkers who toil in the heat remain one of the groups most vulnerable to heat-related illnesses. But another element of their jobs is making extreme heat even more dangerous: pesticide drift.
When it is hotter outside, pesticides tend to evaporate faster, explains Nicole Deziel, an environmental health scientist at the Yale School of Public Health. This, in turn, impacts how much of the pesticide actually reaches the crop. Any that doesn’t usually sticks around in the air—and can travel miles offsite. Pesticide drift means that the toxic chemicals spread further than ever intended, affecting farmworkers and adjacent communities.
Once airborne, those pesticides can linger in surrounding air for as long as five days, according to reports authored by the Pesticide Action Network, an advocacy coalition that opposes their pervasive use in industrial agriculture. Pesticide drift is a common problem that affects nearly every farming community in the US—whether crops are sprayed by hand, through fumigation, or via planes."
