Summary

Researchers assessed the ecotoxicological effects of leachates from plastic items and boat biocide coatings on the harpacticoid copepod Nitokra spinipes under conditions simulating global change, including elevated temperature and ocean acidification scenarios. The study examined how combined stressors from plastic-derived chemical leachates and environmental change factors interact to affect the development and survival of this marine invertebrate test organism.

As plastic production soars to 400 million tons, a substantial proportion of mismanaged waste items and other polymeric litter finds its way from inland areas to water systems, reaching riverine and coastal environments. Within aquatic environments, plastics and (boat) biocide coatings undergo physical degradation, breaking down into microplastics (MPs; Also see: https://micro2024.sciencesconf.org/559348/document
