What Will It Take for the EPA to Ban a Pesticide Linked to Parkinson’s?

Pesticides, Rachel Carson wrote in 1962, have “the power to kill every insect, the ‘good’ and the ‘bad,’ to still the song of birds and the leaping of fish in the streams, to coat the leaves with a deadly film, and to linger on in soil—all this though the intended target may be only a few weeds or insects. Can anyone believe it is possible to lay down such a barrage of poisons on the surface of the earth without making it unfit for all life? They should be called … ‘biocides.’”

Carson’s book, Silent Spring, helped launch the modern environmental movement. But more than six decades later, we are still struggling to heed her warning. Farmlands and lawns in the United States are drenched in about a billion pounds of pesticides per year, according to the U.S. Geological Survey.

The Environmental Protection Agency recently reapproved paraquat, a toxic herbicide, even though a group of environmental and public health groups have been suing the agency for ignoring multiple studies showing paraquat exposure increases a person’s odds of developing Parkinson’s disease. That’s in addition to paraquat’s short-term effects, which can include heart failure, kidney failure, liver failure, and lung scarring if even a small amount of it is ingested, according to the Centers for Disease Control and Prevention. In fact, the CDC fact sheet on paraquat includes the striking recommendation that if you get any on your clothes you should cut the affected garment off your body—because it is too dangerous to pull it over your head and risk ingesting paraquat—and see a doctor immediately. The company that sells paraquat, according to documents leaked to The Guardian in 2022, has known about possible long-term neurological effects since 1975 and deliberately downplayed them. 02-19-24
