Paraquat

 SNAP comment: Historically there were16 paraquat containing pesticides registered in Canada, even some as domestic products (to be used by consumers). The last to be taken off the market was Gramoxone 200 SL on 2022-03-08. As a result, this product, classified as restricted, might still be in use because the PMRA only controls sales not use. Typically a pesticide is used for several years after it is taken off the market as users stockpile it. Research on glaciers indicates that peak deposition for banned organochlorines occurs at least 1 decade after they had been banned and maximum use had occurred in North America. 

Revealed: The secret push to bury a weedkiller’s link to Parkinson’s disease    Internal documents from chemical giant Syngenta reveal tactics to sponsor sympathetic scientific papers and mislead regulators about unfavorable research   (by Carey Gillam, The Guardian, 2 June 2023)     'Those documents showed that Syngenta was aware decades ago of evidence that exposure to paraquat could impair the central nervous system, triggering tremors and other symptoms in experimental animals similar to those suffered by people with Parkinson’s.    They also showed that Syngenta worked covertly to keep a highly regarded scientist studying causes of Parkinson’s from sitting on an advisory panel for the US Environmental Protection Agency (EPA), the chief US regulator for paraquat and other pesticides. The new documents have emerged at a sensitive time for Syngenta. In less than six months, the Swiss chemical giant faces a first-ever trial in litigation brought by US farmers and others who allege the company’s paraquat weedkiller causes Parkinson’s.'
