The phase-out of long-chain perfluorinated compounds (PFCs) by the company 3M in 2000 was followed by the introduction of shorter-chain perfluorinated alternatives. Little, however, is known of the identity, production volumes and applications of these alternatives. A new study published by researchers from the Swiss Federal Institute of Technology ETH Zurich reviews identity, environmental releases, persistence and exposure of 20 such alternatives. The researchers stress the need for more accurate analytical techniques and more sophisticated environmental fate, toxicity and bioaccumulation study designs. The FPF reports on the study’s findings.
