22 Aug 2019 --- The long-awaited findings of the World Health Organization’s (WHO) assessment of microplastics in the environment have been published, with the organization indicating that the impact on human health appears to be minimal at current levels. At the same time, WHO has stressed that it was working from “limited information” and that there is a pressing need to establish more standardized methods for measuring microplastic particles in water; more studies on the sources and occurrence of microplastics in freshwater; and the efficacy of different treatment processes.
