To date, field investigations on the temporal and spatial distribu Compared with rivers, lakes are more sensitive to the responses of ecosystem environment and biodiversity. Therefore, the accumulation of microplastics in lakes with high human activity would pose a serious threat to ecological security (Lu et al., 2019). In short, among the different area in same river system, the spatial distribution ...Microplastics and other anthropogenic microparticles are present in Lake Simcoe but at lower abundances than at locations impacted by larger population centers in other large freshwater lakes such ...

Microplastics, i.e., plastic particles in the size range of planktonic organisms, have been found in the water columns and sediments of lakes and rivers globally. The number and mass of plastic particles drifting through a river can exceed those of living organisms such as zooplankton and fish larvae. In freshwater sediments, concentrations of microplastics reach the same magnitude as in the ...The microplastics were dominated by fiber, 100-1000 μm in size and cellophane in composition.
