ABSTRACT Microplastics and antibiotics are emerging pollutants that accumulate extensively in soils, both exerting adverse effects on soil ecosystems. The mechanisms underlying the combined of microplastics microbial metabolism remain insufficiently understood. Therefore, we evaluated individual different types (non‐degradable polyethylene biodegradable polylactic acid) an antibiotic (oxytetracycline) characteristics. Our results showed community was primarily limited by nitrogen under either or treatments; whereas it phosphorus treatments. All treatments, except for non‐biodegradable microplastic treatment, significantly alleviated carbon limitation ( p < 0.01), with effect being particularly pronounced treatments involving antibiotics. Notably, increased use efficiency 0.05). were influenced type their interaction antibiotics, highlighting complex nature these environmental pollutants. This study provided empirical basis understanding exposure co‐exposure to biodegradable/non‐biodegradable metabolism.
