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.
Ease of plastics production has caused high usage in many areas from water bottles, furniture and packaging to cosmetics during the last decade. Plastic products cause environmental pollution due to the high demand in the industry. It is known that pesticides are used to prevent various pests in order to increase production efficiency. With the use of such substances, there is considerable growth in the amount of product. However, pesticides remain on the water, soil, fruits, and vegetables for a long time, causing environmental pollution and thus leading to various damages that can reach people through the food chain. Since some of the mostly found pesticides in the environment are endosulfan and endrin, the sorbing capacities of endosulfan and endrin on microplastics have been investigated. The kinetic parameters at 23 and#176;C in ultrapure water, hexane and saline water have been tested to show the effect of solvents on sorption behaviors.

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.
The role of microplastic aging on chlorpyrifos adsorption-desorption and microplastic bioconcentration
AI summary Read the abstract
Researchers investigated how microplastic aging affects chlorpyrifos adsorption-desorption behavior, finding that aged microplastics had higher pesticide sorption capacity and bioconcentration potential, suggesting weathered MPs pose greater risks as pollutant carriers.
Study of the Potential Accumulation of the Pesticide Alpha-Endosulfan by Microplastics in Water Systems
AI summary Read the abstract
Researchers studied whether microplastics accumulate the organochlorine pesticide alpha-endosulfan from contaminated water and assessed the potential for trophic transfer to aquatic organisms. Microplastics adsorbed the pesticide and could act as a vector for its transfer up the food chain, potentially increasing exposure risk in organisms that ingest MPs.
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.
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.
