Microplastics reshape soil carbon cycling via microbial-mediated mechanisms in black soil ecosystems
This study investigated the effects of polyethylene (PE) and polylactic acid (PLA) microplastics at different concentrations on soil bacterial communities in black soil using 16S rRNA amplicon sequencing. Soil samples were collected from a controlled pot experiment at 120 days. Bacterial community composition and diversity were analyzed to explore the impact of microplastics on soil microbial ecology.
