observed in lakes from remote areas in Mongolia and in central Tibet. Waste management systems need to be improved in these developingAsian countries to mitigate the microplastic pollution problems. Along with abundance, features of microplastic samples such as shapes, sizes, colors, surface textures, and polymer typesweremeasured in thesestudies,whichcanbeused to interpret theoriginsand experiencesof themicroplastics.Thesepreliminary results call for further research efforts to better understand the sources and fate ofmicroplastics in inlandwaters. The biological and ecological risk of microplastic exposure should be assessed especially at environmentally relevant circumstances. Sampling, pretreatment, and reporting of microplastics should be standardized for the future monitoring programs. References 1.AndradyAL,NealMA (2009)Applications and societal benefits of plastics.
