In Vitro Sorption Study of Some Organochlorine Pesticides on Polyethylene Terephthalate Microplastics
AI summary Read the abstract
Researchers found that organochlorine pesticides adsorb significantly (up to 50%) onto PET microplastic surfaces in laboratory conditions, with adsorption rates varying by compound hydrophobicity. This confirms that microplastics can concentrate pesticide pollutants and potentially transport them to organisms that ingest the particles.
The main objective of this study was to investigate the adsorption processes occurring on the surface of microplastic particles using an important class of organic pollutants (organochlorine pesticides). The adsorption study of some organochlorinated compounds has shown that these compounds, being in contact with microplastic particles, can be significantly adsorbed (up to 50% of the added amount controlled in the in vitro study depending on hydrophobicity and water solubility) on their surface and can be transported in natural waters. Contaminated particles may be ingested by aquatic organisms and may bioaccumulate there in causing damage to the entire trophic chain.

Adsorption behaviors of atrazine and imidacloprid on high temperature aged microplastics: Mechanism and influencing factors
AI summary Read the abstract
Researchers investigated how aged polyethylene microplastics — the kind that have been weathered by UV light and heat in the environment — adsorb common agricultural pesticides, finding that microplastics can accumulate pesticides like atrazine and imidacloprid at high concentrations through hydrophobic (water-avoiding) interactions. This "Trojan horse" effect means microplastics can carry and potentially concentrate pesticides as they move through water environments.
Hydrophobic Pesticide Endosulfan (α + β) and Endrin Sorption on Different Types of Microplastics
AI summary Read the abstract
This study examined how two hydrophobic pesticides — endosulfan and endrin — adsorb onto different types of microplastic particles in water. The findings show that microplastics can act as carriers for persistent pesticide pollutants, potentially increasing the mobility and bioavailability of these chemicals in aquatic environments.
Sorption and dissipation of current-use pesticides and personal-care products on high-density polyethylene microplastics in seawater
AI summary Read the abstract
Researchers characterized how three pesticides and three personal care products sorb onto high-density polyethylene microplastics in seawater. They found that more hydrophobic compounds accumulated more readily on the plastic, and that significant desorption (over 30%) occurred within 24 hours, especially at higher contaminant concentrations. The study confirms that microplastics can act as both carriers and releasers of chemical pollutants in marine environments.
Hydrophobic Pesticide Endosulfan (α + β) and Endrin Sorption on Different Types of Microplastics
AI summary Read the abstract
Researchers studied how plastic particles of different types sorb the hydrophobic pesticides endosulfan and endrin from water. They found that plastic type and aging significantly affected sorption capacity, with more weathered plastics accumulating higher pesticide concentrations. The results demonstrate that plastic debris can act as a carrier for persistent organic pesticides in aquatic environments.
Determination of organochlorine pesticides adsorbed on plastic pellets
AI summary Read the abstract
Researchers analyzed organochlorine pesticides adsorbed onto plastic pellets found in coastal environments, contributing to understanding of how plastic debris accumulates and concentrates toxic chemicals. Plastic pellets, a type of microplastic, can act as carriers bringing persistent organic pollutants into marine food webs.
