Impacts of polyethylene microplastics on soil microbial communities and metabolism in broomcorn millet (Panicum miliaceum L.).
Polyethylene (PE) microplastics (MPs) are the predominant MP pollutants in agricultural soil ecosystems. To investigate the underlying mechanisms associated with high-load exposure, a controlled pot experiment was conducted to evaluate the effects of pristine PE MPs (1%, 2%, and 3% w/w, ∼100 μm) on soil physicochemical...
