C&EN contacted MEPA and members of the scientific committee with questions about what kinds of samples were gathered, what testing was being done, and what data they had collected on marine animal mortality. Committee members were reluctant to talk given MEPA’s stipulation that all findings must be kept secret ahead of potential international court filings.

A quick perusal of C&EN’s copy of the 1946 collection featured in the movie does reveal some interesting topics—including an eyewitness account of an atomic bomb explosion in the Pacific and a report on the stability of penicillin. But it doesn’t give much insight into how to make your own sentient robot.

The exposome is the collection of a person’s chemical and biological exposures over time. The goal in exposome science is to measure these exposures and map them to the individual’s health. Techniques to sequence the exposome typically involve measuring biomarkers in the blood or saliva. These samples provide a recent snapshot of a person’s surroundings.

The researchers analyzed PFAS data collected from 2013–2015 by the US Environmental Protection Agency on more than 500 freshwater fish. They found an average of 9.5 ppb PFAS in fish from US rivers and streams and 11.8 ppb in fish from the Great Lakes. Perfluorooctanesulfonic acid (PFOS) was the most commonly found PFAS, averaging 74% of the total PFAS.

The EPA must collect that amount from industry paid user fees to offset the costs. The EPA proposed raising TSCA-related fees in November and will have to do so this year to comply with the 2023 appropriations bill. Those fees, paid by chemical manufacturers, help support the agency’s review of the safety of new chemicals and those already on the market that may pose a health risk. The EPA can collect up to 25% of the cost of reviewing chemicals from industry-paid user fees, but so far those fees have covered only about 12% of the costs. /policy/chemical-regulation/World-Chemical-Outlook-2023-Another-challenging-year-ahead-for-US-chemical-regulators/101/i2 20230111 Concentrates 101 2 /magazine/101/10102.html World Chemical Outlook 2023: Another challenging year ahead for US chemical regulators chemical regulation, US EPA, TSCA con govpol Britt E.

The first requirement will be new disclosure forms that agencies use to collect information about a principal investigator’s funding sources. The goal is to make those forms—the biographical sketch and a list of current or pending funding —the same across all federal research agencies. The standardization is intended to streamline work for scientists applying for grants and eliminate confusion about what they need disclose to the government.
