Sorption of Pollutants on Microplastics
AI summary Read the abstract
Researchers reviewed how microplastics act as sponges for other pollutants in the environment, absorbing toxic chemicals like pesticides and heavy metals and potentially carrying them into the food chain, compounding the health risks of plastic contamination beyond the particles themselves.
This chapter presents the different aspects involved in the study of pollutant sorption on microplastics (MPs). Introductory descriptions of the sorption processes are presented. The study of sorption capacity at equilibrium and kinetics is important to better...

Sorption of Pollutants on Microplastics
AI summary Read the abstract
Researchers reviewed how microplastics act as sponges for environmental pollutants like pesticides, heavy metals, and pharmaceuticals, absorbing and concentrating these chemicals in ways that can amplify their toxicity when ingested by marine animals — and potentially by humans.
Factors Affecting the Sorption of Pollutants by Microplastics: Mechanisms and Environmental Implications
AI summary Read the abstract
Researchers reviewed the physicochemical factors — including particle size, surface area, weathering state, and polymer type — that govern how microplastics sorb environmental pollutants, and examined the ecological implications of this vector effect for contaminant transport and bioavailability.
Plastic Pollution Amplified: Adsorption of Contaminants onto Microplastic Surfaces
AI summary Read the abstract
This review examined how microplastics act as vectors for co-pollutants — including heavy metals, persistent organic pollutants, and pharmaceuticals — adsorbing these substances onto their surfaces and potentially delivering concentrated doses to organisms that ingest them. The "Trojan horse" effect of microplastics as contaminant carriers significantly amplifies their toxicological risk beyond the particles themselves, with direct implications for human health via contaminated seafood and drinking water.
Interaction Between Microplastics and Pollutants
AI summary Read the abstract
Researchers examined how microplastics interact with environmental pollutants, finding that their accumulation causes physical harm including suffocation and energy depletion in aquatic organisms, while their surfaces act as vectors that concentrate and transport co-contaminants through ecosystems in various forms including films and fragments.
Sorption of Potentially Toxic Elements to Microplastics
AI summary Read the abstract
Researchers reviewed how microplastics can adsorb toxic heavy metals from their surrounding environment, effectively acting as vehicles that concentrate and transport harmful elements. This sorption behavior increases the potential risk microplastics pose to organisms that ingest them, including humans.
