Summary

This review examines the phytotoxic effects of nano- and microplastics on crop species, summarizing research conducted since the field emerged in 2016. Researchers found that plastic particles can damage plant tissues through both direct and indirect mechanisms, and that nanoplastics can enter plant cells and accumulate in edible organs. The study notes that contradictory results across studies make it difficult to draw firm conclusions, pointing to the need for more standardized research approaches.

Plastic pollution is one of the most impactful human interferences in our planet. Fragmentation of plastic leads to nano- and microplastics (NP/MP) formation, which accumulate in agricultural lands, representing an increasing risk for crop production and food safety. It has been shown that MP promote damage in plant tissues by several direct and indirect ways, and that NP can enter the tissues/cells and accumulate in edible organs. Investigation of the phytotoxic effects of NP/MP in plants started only in 2016, with most of the studies performed with crops. Since contradictory results are often observed, it is important to review the literature in order to identify robust effects and their possible mechanisms. In this review, we discuss the potential of NP/MP in damaging crop species, with focus on the physiological changes described in the literature. We also performed scientometrics analyses on research papers in this field during 2016-2021, to reveal the research situation of phytotoxic effects of plastic pollution in crops. Our review is as a starting point to help identify gaps and future directions in this important, emerging field.
