Science Friday · Use of herbicide linked to Parkinson's is on the rise in the US · 20 May 2026 podcast

I love Science Friday.

Yeah, this is a plant in Waynesboro, Mississippi, which is a small, quite rural town.

And at this plant, they formulate and repackage paraquat.

So paraquat is this cheap, super toxic, what they call burndown agent herbicide.

So we don't make paraquat in the

Now it is mostly made in China or the UK and it's imported to the US.

Where it's banned, right?

Where it's banned.

It's banned in China.

It's banned in the UK.

It's banned in the EU.

It's banned in Brazil.

It's banned in more than 70 countries because it is, again, so, so poisonous.

So what is the plant doing exactly?

Right.

So they take this chemical, paraquat, and they add some other little chemicals and additives, and then they repackage it.

They are turning it into a product that then gets distributed and sold to farmers.

Yeah, so Paraquad is not technically considered an air pollutant.

So it's not something like ozone that's regulated by the federal government and says, hey, if your facility emits over a certain amount of this, you have to get a permit.
