Evaluates how microplastics influence atrazine adsorption and degradation in soils, suggesting potential environmental risks.

The study aims to assess how different types of microplastics affect atrazine behavior in agricultural soils.
Conducted batch adsorption experiments with microplastics and atrazine in two soil types.
Performed a 90-day degradation experiment to monitor atrazine persistence and soil enzyme activity.
Analyzed adsorption kinetics using pseudo-second-order and Freundlich isotherm models.
Microplastics increased atrazine adsorption capacity in soil, ranging from 6.80 to 39.93 mg kg−1.
PVC showed the strongest inhibitory effect on atrazine degradation among the microplastics studied.
The half-life of atrazine varied between 22.97 to 81.76 days, influenced by the type of microplastic and soil.

Cheng et al. (2026) studied this question.
