Taking a first principles look at tattoo ink and its potential toxicity

EPA begins taking steps toward PFOS and PFOA regulation.

A short story on how I became the first person to find microplastics in an aquifer.

Today the EPA published adjusted interim PFAS drinking water Health Advisory levels for PFOA and PFOS from 70 ppt (ng/L) combined to 0.004 ppt for PFOA, 0.02 for PFOS, 10 ppt for Gen X, and 2,000 ppt for PFBS (the Gen X and PFBS Health Advisory levels were new).

Whenever I talk to someone about PFAS, and they actually know what they are, I inevitably get asked questions about exposure risk. “should I avoid this?”, “I heard this has PFAS in it!”, “two towns over has it in their water.”, “NON-STICK PANS!!! NON-STICK PANS!”. So, I thought I’d write down some of my opinions and thoughts on possible PFAS exposure sources and somewhat classify them by severity.

PFAS are probably a chemical you’ve seen in the news recently. If you haven’t yet… you probably will soon. It’s a topic that’s near and dear, I ‘ve spent the last 7 years of my life studying them… so figuring out what to not put in was the more difficult part.
