So I think the three environmental toxicants that are principally responsible for the rise in Parkinson's disease are certain pesticides, the poster child for them being a pesticide called Paraquat, widely used as a weed killer. The second are commonly used dry cleaning chemicals, including this one called trichloroethylene.

And the third is one familiar to Southern Californians, and that's air pollution.

So trichloroethylene, or TCE, is a really, really simple molecule. So your listeners all know that water is H2O, which means it just has three atoms, two hydrogens, and one oxygen. Trichloroethylene is very simple. It's got six atoms. It's got two carbon atoms in black, one hydrogen atom in white, and three chlorine atoms in green, hence its name, trichloroethylene.

This chemical was initially developed in 1864, so I think at the time of President Abraham Lincoln was the president, and it's been used since the 1920s, so since shortly after World War II. And it's been used in everything. It's been used to decaffeinate coffee. It was found in Senko or other decaffeinated coffees in the 1970s.

It's been used to degrease metal, and it's been used to dry clean clothes. It's found in carpet cleaners. It's found in gun cleaners. It's found in typewriter correction fluid. It's found in a wide variety of consumer goods. And this chemical is known to cause cancer. There's no question about that. The EPA says it's carcinogenic by all routes of exposure.

The World Health Organization says that it causes cancer. And yesterday, the EPA long-lasted proposed a ban on nearly all uses of trichloroethylene in the United States. And this ban would go in effect in a year. And I think by taking that action, they are preventing generations of individuals from developing cancer in the future.

And I think they're also likely preventing generations of individuals from developing Parkinson's disease in the future. However, the Problem is not just the use of trichloroethylene, which in the 1970s, it's estimated that 10 million Americans worked with this in semiconductor industry, in mechanics, in printers and painters and taxidermists and varnish workers all worked with it.
