identification of microplastics were published recently [66–68]. An overview of the advantages and limitations of these techniques is summarized inTable 2. In the Three Gorges Reservoir, only PE, PP, and PSwere identified from the recoveredmicroplastics, which may be related to their lower density. The weak hydraulic conditions of the ThreeGorges Reservoir will generally favor the sedi- mentationofmicroplasticsoriginatingfromdenserpolymertypes[22].Inlakeshore sediments fromSilingCo basin, PE and PPwere predominant, while PVC, PET, and PS were only identified from one sampling site [23].
