Tiny pieces of plastic are an increasingly big problem. Known as microplastics, they originate from clothing, kitchen utensils, personal care products, and countless other everyday objects. Their durability makes them persistent in the environment – including in human bodies. … According to a new literature review, a significant portion of our microplastic exposure may come from drinking water, as wastewater treatment plants are still not effectively removing microplastics. … ”What our systematic literature review found is that while most wastewater treatment facilities significantly reduce microplastics loads, complete removal remains unattainable with current technologies,” says senior author Un-Jung Kim, environmental engineer at the University of Texas at Arlington (UTA).
