I was a bit surprised when reading the following paragraph in the article "The Louisiana Environmental Apocalypse Road Trip":
The risk of cancer in Reserve, a community founded by freed slaves, is 800 times the national average, making the community, by one EPA metric, the most carcinogenic census tract in America—the cause is a DuPont/Denka chemical plant adjacent to the town that annually spews 250,000 pounds of the likely carcinogen chloroprene into the air.
A quick look at the safety data sheet for chloroprene confirms that it's not something I'd like to breathe, even if you ignore the potential carcinogenicity. And 250,000 pounds (113 tons) per year seems like a very high amount to me, for a substance as toxic as chloroprene.
I looked around a bit, but all other articles I saw about the subject don't actually mention this number.
Is that article accurate, and the plant did actually emit that much chloroprene?
