As far back as 1975 corporate insiders were aware of potential risks. They called #paraquat’s long-term effects "a quite terrible problem” (Nov 11, 1975 ltr to #Chevron Environmental Health, Standard Oil of California).

Most US paraquat comes from China & UK—both banned paraquat’s use in their countries.
