TL;DR: This Critical Review provides a critical review of the current knowledge vis-à-vis nanoplastic (NP) and microplastic (MP) aggregation, deposition, and contaminant cotransport in the environment and highlights key knowledge gaps that need to be addressed.

TL;DR: An overview of the current knowledge of the abundance and distribution of microplastics and associated contaminants in African aquatic systems and organisms is provided and major gaps in sampling and identification techniques which may have overestimated or underestimated the current levels were identified.

TL;DR: In this article, international standard weathering protocols developed for polymers were critically analysed for their appropriateness for use in microplastics research and it was shown that most studies using weathered micro-plastics involve sorption experiments followed by toxicity assays.

TL;DR: It is shown that nanoplastics will largely aggregate and associate with soils rather than undergo long range transport in groundwater in colder climates following freezing temperatures, and the need to account for climate and temperature changes when assessing the risks associated with nanoplastic release in aquatic systems is highlighted.

TL;DR: In this paper , the authors investigated the number of microfibres released in the presence and absence of UV irradiation and mechanical friction and the removal of the released micro fibres in a simulated conventional wastewater treatment process.
