For PFAS, hazardous designation is not a ban
News
15 Oct 2019 | EWG News
Designating PFAS as “hazardous substances” is critical to cleaning up legacy contamination [and is different than a ban]. There are currently 761 substances on the CERCLA hazardous substances list. Almost 700 of them have been on the list since the law was passed in 1980. An EWG analysis found that at least 599, or 79 percent of these chemicals are likely still in active use in commerce today. What’s more, 339 of the CERCLA hazardous substances chemicals, or 44 percent, are not only in production, but likely produced at high volumes.

The toxic chemicals have been showing up in milk around the country. Anna Reade, an NRDC staff scientist specializing in toxic chemicals, suggests that state agencies test sludge before it’s spread on fields and milk before it goes to market. Then officials could see where the highest PFAS concentrations are coming from.

‘Forever chemicals’ are in your popcorn—and your blood
News
10 Oct 2019 | Wired
According to a recently published peer-reviewed study, the more often people eat at home, the lower their level of PFAS chemicals. Also, people who reported eating microwave popcorn had significantly higher levels of four types of PFAS. Additionally, the study linked PFAS levels in blood to a diet high in shellfish, which can accumulate those chemicals from contaminated water.
