EarthTalk – What are PFASs and should we be concerned?

Dear EarthTalk: What are PFASs and why should we be concerned about them? -- Jim Stobbins, Cary, NC

PFASs—short for perfluoroalkyl substances—are synthetic chemicals of various formulations (including PFCs, PFOA, PFOS and GenX, among others) that are used widely in various products for moisture and stain resistance. Non-stick pans, rain jackets and carpeting are among thousands of different types of consumer goods that now contain one form or another of PFASs.

I think there must be autumnal reasons for Halloween being hued in orange and black. It’s a fun time, a magic evening if you’re a kid, and if you’re a grandpa-type guy, like me, who gets to hand out the goodies.

But the colors of this sweet evening celebration are orange and black, and so is October. In another week or so, our deciduous trees will stand like skeletons against the gray skies of winter, but now we have the orange and black of fall.
