Microplastics in lakes
Jul 14, 2023 · Researchers first reported microplastics in Lake Tahoe in 2019 — a disappointing discovery about the lake, which straddles California and Nevada. Decades of conservation efforts and legal ... Large quantities of microplastics (MPs) are discharged into the hydrosphere via the municipal wastewater treatment plant (WWTP) as an important route. Herein, we sampled the influent, effluent and sludge of WWTP in order to investigate the abundance, size, type, and shape of MPs. The detected MPs were primarily in the shape of fiber with the abundance up to 44 particles per liter. Polyethylene ...There is mounting evidence that microplastics present a significant threat to aquatic organisms. Microplastics – defined as plastic particles less than 5 mm in diameter – come from many different sources, including synthetic textiles, industrial waste products, personal care products, and the breakdown of litter, car tires, and other objects.
