Colonization of microplastics and transformation of sorbed PCBs by a marine microbial community
AI summary
This study examined the effects of polyvinyl chloride (PVC) microplastics on zebrafish embryo development, assessing morphological abnormalities and developmental endpoints. PVC exposure caused dose-dependent increases in developmental malformations including pericardial edema, yolk sac absorption defects, and spinal curvature.

Marine Microplastics: Abundance, Ecotoxic Consequences of Associated Anthropogenic Contaminants and Interactions with Microorganisms
AI summary Read the abstract
Researchers reviewed the rapid growth of microplastic pollution in the ocean, highlighting how these particles accumulate toxic chemicals and interact with microorganisms in ways that amplify their ecological harm. As plastic production continues to rise, the marine food web faces increasing exposure to contaminated microplastics that can ultimately reach humans through seafood.
Microbial Relationship of Marine Microplastics
AI summary Read the abstract
Researchers examined how microplastics in the ocean interact with microbial communities, finding that plastic surfaces attract and harbor unique assemblages of bacteria — a concern because these 'plastisphere' microbes can spread pathogens and antibiotic-resistant genes through marine food chains.
Ecological Effects of Chemical Contaminants Adsorbed to Microplastics
AI summary Read the abstract
Microplastics act as vectors for adsorbed chemical contaminants including pesticides, heavy metals, and persistent organic pollutants, amplifying their transport and bioavailability in aquatic and soil ecosystems. The combined exposure to plastic particles and their chemical cargo poses greater ecotoxicological risks than either contaminant class alone.
Ecological Effects of Chemical Contaminants Adsorbed to Microplastics
AI summary Read the abstract
Researchers reviewed how chemical contaminants that bind to microplastics — including pesticides and heavy metals — affect aquatic and soil organisms, finding that microplastics can both concentrate toxins and amplify their biological impact. This so-called Trojan horse effect may make microplastic pollution more ecologically harmful than the plastic alone would suggest.
