overestimating the ecotoxicity of microplastics”, comments Carmen Martín, researcher at the PLANGER Plant Germplasm Research Group of theHigher Technical School of Agronomic, Food and Biosystems Engineering (ETSIAAB) of the UPM, which has been part of the research team that carried out the study. The results showed that C. elegans was the least sensitive organism, while L. sativa showed high toxicity to microplastics. One of the tested plastic residues induced a 70% reduction in seed germination and, with both types of residues, a significant decrease in development was detected, both of the leaves and of the root (in L. sativa) that also reached values ​​around 70% inhibition of development. Their potential role as contamination

Its use would make it possible to

establish clear regulations that mainly affect food safety. “However, the scarcity of data on potential risks of microplastics in the terrestrial ecosystem, implies that these studies could contribute to describe their function as” vectors of pollution “and, therefore, to assess their impact on said ecosystem. ”Conclude the researchers.
