TL;DR: In this article, the authors identify the main aspects concerning microplastics pollution sources in lakes and rivers, with a focus on freshwater sediments as a site of accumulation and as the habitat of benthic organisms.

TL;DR: This study highlights the occurrence of a prompt and complex response in the fate and distribution of POPs to dynamic biogeochemical control within the frame of the ecological succession, phytoplankton and zooplankon biomass dynamics produced bioaccumulation metrics varying over 1-2 orders of magnitude in the time frame of a few weeks and resulted in reduced trophic web exposure.

TL;DR: Though survival of the organisms remained unaffected, sublethal effects were in agreement with the measured concentrations of the principal persistent organic pollutants and should be included as part of environmental monitoring efforts as a basis for assessing the recovery of the river.

TL;DR: The large presence of NPs inside midgut cells after only 48-h exposure to nanoZnOs and their effects on the intestinal cells highlighted the toxic potential of these nanomaterials, also suggesting that studies on chronic effects are needed.

TL;DR: A sharp increase in 2005 of pp'DDT and its metabolites was observed in mussels and fish from lakes Como and Iseo, the main glacier-fed southern Alpine lakes, and PCBs did not peak in biota tissues to a comparable extent probably because local sources were not as important as for DDTs.
