Toxicity of microplastic particles and adsorbed fluoranthene to epibenthic copepods
Summary
This is a duplicate entry of paper 79014, describing the same study on polyethylene microplastics and fluoranthene-coated microplastics affecting epibenthic copepods over 32 days. Both the physical particles and the attached chemical were found to cause harm to growth, reproduction, and survival of these tiny marine invertebrates.
This study focuses on the chronic uptake of polyethylene microplastics in the gut of the epibenthic copepod, Amphiascus tenuiremis, for a period of 32 days. Uptake is quantified during the three developmental stages, and the resulting growth, reproduction, and mortality is quantified. Polyethylene microplastics used in this study ranged between 10 and 27 microns. The same polyethylene microplastics were saturated with the polycyclic aromatic hydrocarbon, fluoranthene, and the bioavailability of fluoranthene to adult copepods was also quantified following 7 day exposures.

Toxicity of microplastic particles and adsorbed fluoranthene to epibenthic copepods
Researchers exposed small bottom-dwelling copepods to polyethylene microplastics and fluoranthene-coated microplastics over several weeks, measuring effects on growth, reproduction, and survival. The study found that both the plastic particles and the attached chemical caused toxic effects, providing evidence that microplastics and their sorbed pollutants harm even tiny marine invertebrates.
Transfer of POPs to Grass Shrimp Following Ingestion of PAH-Coated Microplastic
This is a duplicate entry of paper 79013, describing the same study on fluoranthene transfer from PAH-coated microplastic to grass shrimp following ingestion. Researchers found that toxic PAH chemicals sorbed onto microplastics can transfer to marine crustaceans after ingestion.
Transfer of POPs to Grass Shrimp Following Ingestion of PAH-Coated Microplastic
Researchers exposed grass shrimp to microplastic particles coated with a toxic PAH chemical called fluoranthene to test whether ingesting plastic transfers the attached chemical into the shrimp's body. The study found that fluoranthene transferred to shrimp following ingestion, demonstrating that microplastics can serve as vectors carrying toxic chemicals into marine organisms.
Do functional traits and biochemical biomarkers of the nematode Oncholaimus campylocercoides De Coninck and Schuurmans Stekhoven, 1933 affected by fluoranthene and polystyrene microplastics? Results from a microcosm bioassay and molecular modeling
Researchers examined the effects of polystyrene microplastics and fluoranthene, alone and combined, on the marine nematode Oncholaimus campylocercoides, finding measurable changes in morphometry, functional traits, and biochemical biomarker activity from both single and combined exposures.
Exposure of marine mussels Mytilus spp. to polystyrene microplastics: Toxicity and influence on fluoranthene bioaccumulation
Researchers exposed marine mussels to polystyrene microplastics alone and in combination with the pollutant fluoranthene to study their combined effects. They found that while the microplastics themselves had limited direct toxicity, they influenced how fluoranthene accumulated in and was cleared from the mussels' tissues. The study suggests that microplastics can alter the way marine organisms interact with chemical pollutants, potentially changing the risks these contaminants pose.
