Further research is needed to understand the factors influencing ingestion patterns. Studies should investigate the effects of synthetic microparticles on freshwater invertebrates and their role in aquatic food webs. Research should focus on developing strategies to reduce plastic pollution in aquatic ecosystems.

Further studies are needed to investigate the effects of microplastic pollution on aquatic ecosystems. The development of strategies to mitigate microplastic pollution in shallow lakes and reservoirs is necessary. The use of a combination of experiments and simulations to investigate microplastic transport should be further explored.
