PFAs and Microplastics Become More Toxic When Combined, Research Shows

Few human-made 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.
The enhanced toxic effects raise alarm because PFAS and microplastics are researched and regulated in isolation from one one another, but humans are virtually always exposed to both. The research also showed those fleas previously exposed to chemical pollution were less able to withstand the new exposures.
