Interactions of microplastics with pesticides and anthelminthics mediate undesirable effects on microbial nitrogen cycling in agricultural soils.

ABSTRACT: Microplastics (MPs) frequently co-occur with pesticides and veterinary medicines in agricultural soils. However, their interactive effects on soil microbiota remain largely unknown. Therefore, we investigated the effects of three MP types (LDPE-, PBAT-, and starch-based), applied at two concentrations (0.01% and 0.1%), either alone or in combination with the fungicide pyraclostrobin and/or the anthelminthic albendazole (ABZ), on soil microbial functioning. Nitrate levels, nitrification rates, ammonia-oxidizing microorganisms, and denitrifying bacteria served as indicators of perturbations on soil N cycling in soils from France, the Netherlands, and Greece. Microbial responses were soil-dependent, with the Greek soil being the most affected. In contrast, plastic type- and dose-dependent eff
