Study detects synergistic effect making substances more dangerous, raising alarm since humans are exposed to both

Few manmade substances are as individually ubiquitous and dangerous as PFAS and microplastics and when they join forces there is a synergistic effect that makes them even more toxic and pernicious, new research suggests.

The study’s authors exposed water fleas to mixtures of the toxic substances and found they suffered more severe health effects, including lower birth rates, and developmental problems, such as delayed sexual maturity and stunted growth.
