Factors Affecting Bioavailability and Toxicity of Lead, Mercury, Organochlorides, Antibiotics, and Micro- and Nanoplastics in Marine and Oceanic Sediments
AI summary Read the abstract
Researchers review how environmental factors alter the bioavailability and toxicity of marine sediment contaminants — including lead, mercury, organochlorine pesticides, antibiotics, and micro- and nanoplastics — examining how sediment chemistry, organic matter, and physical conditions interact to determine pollutant uptake and harm to marine organisms.
This chapter deals with the aspects responsible for changing the bioavailability and toxicity of organochlorine pesticides, antibiotics, mercury, and lead in marine and oceanic sediments. In this context, integrated discussions, which contemplated the effects of...

Pollutants Bioavailability and Toxicological Risk from Microplastics
AI summary Read the abstract
Microplastics function as vectors for toxic chemicals — including persistent organic pollutants and heavy metals — adsorbing and concentrating these compounds before being ingested by organisms, which elevates bioavailability and toxicological risk beyond the particles themselves. This chemical hitchhiker effect means microplastic ingestion exposes organisms, including humans, to a broader and more potent cocktail of contaminants than particle size alone would suggest.
Pollutants Bioavailability and Toxicological Risk from Microplastics
AI summary Read the abstract
Researchers reviewed how microplastics act as carriers for toxic chemicals, making them available to living organisms across all environments — from mountain peaks to ocean trenches. The combined chemical and physical burden microplastics place on organisms raises significant concerns for long-term human and ecological health.
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.
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.
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.
