A summary of eight studies; scientists quantify per- and polyfluoroalkyl substances (PFAS) in French fast food packaging; detect eleven PFAS in baking trays from China but not Spain; find PFAS in straws made of paper, bamboo, glass, and plastic; “compostable” service ware can contaminate compost with PFAS; find PFAS in edible oil worldwide; further articles focus on PFAS in drinking water, in Asia, and effects on child respiratory health

Four recent studies assess microplastics: in human semen, heart, from baby food containers, and suitability of in vitro models to investigate human health effects; find microplastics in six out of ten semen samples, find impacts on semen quality; samples from cardiac surgery patients contain microplastics in heart and surrounding tissue; billions of nano- and microplastics released from plastic baby food containers; outline challenges and recommendation of studying plastic particles in vitro
