Assessment of the effects of leachates from plastic items and boat coatings on Nitokra spinipes in the context of global change
AI summary Read the abstract
Researchers assessed the toxicological effects of leachates derived from plastic items and boat antifouling coatings on the marine harpacticoid copepod Nitokra spinipes, exposing this ecotoxicology test organism to extracts generated as plastics and biocide-containing coatings physically degrade in aquatic environments. The study evaluated how chemical leaching from both plastic debris and boat coatings affects crustacean survival and reproduction, contributing to understanding of the combined chemical hazards of plastic pollution in coastal waters.
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

Assessment of the effects of leachates from plastic items and boat coatings on Nitokra spinipes in the context of global change
AI summary Read the abstract
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.
Toxicity of leachate from weathering plastics: An exploratory screening study with Nitocra spinipes
AI summary Read the abstract
This screening study tested leachates from 21 weathered plastic products for acute toxicity to the marine copepod Nitocra spinipes, finding that 38% of plastics produced toxic leachates. Toxicity varied by plastic type and UV irradiation duration, with some plastics becoming more toxic after irradiation and others less so, demonstrating that weathering alters plastic leachate hazard profiles.
Can leachates of environmentally relevant concentrations of microplastics in marine sediments affect the reproduction of an epibenthic copepod?
AI summary Read the abstract
This study evaluated whether leachates from microplastics at environmentally realistic concentrations in marine sediments could affect the reproduction of an epibenthic copepod, without direct particle ingestion. Results provided insights into whether dissolved chemicals leaching from microplastics pose risks to benthic organisms at concentrations actually found in marine environments.
New insights into the impact of leachates from in-field collected plastics on aquatic invertebrates and vertebrates
AI summary Read the abstract
Researchers tested chemical leachates from different types of beach-collected plastics on a range of marine organisms and found that fishing nets, hard plastic containers, and trawling rubber were the most toxic. The plastics released over 30 chemical additives, with some causing death or developmental problems in crustaceans, sea urchins, jellyfish, and fish larvae. This study highlights that microplastic pollution harms marine life not just through physical ingestion but also through the toxic chemicals plastics release into the water.
Combined effects of global warming and microplastic exposure from individual to populational levels of a benthic copepod
AI summary Read the abstract
This study assessed the combined effects of global warming and microplastic exposure on freshwater and marine organisms across individual and population levels, examining how climate and plastic pollution interact as co-occurring stressors. Results showed that warming conditions modified microplastic toxicity in ways that suggest climate change will alter the ecological risk of plastic pollution in aquatic systems.
