"Paraquat, one of many pesticides that can’t be used in Europe but is sold in the United States and elsewhere, has been linked to Parkinson’s disease in a growing body of research."

"HUDDERSFIELD, England — The factory here, set amid a brick campus in a green and hilly industrial town, recently celebrated its centennial.

It produces paraquat, one of the world’s most enduring weed killers — but not one that can be purchased in this part of northern England, in the rest of Britain or across the Channel in the rest of the European Union.

So it will be sent to the United States, or another part of the globe that still allows paraquat to be sprayed on weeds.

Paraquat has long been controversial because of its use in suicides in many parts of the world, since drinking one sip can be lethal. But now regulators in the United States are grappling with a wave of research linking paraquat to a less immediately apparent effect — Parkinson’s disease."
