Concentration threshold for polyethylene microplastics impacting nitrogen transfor-mation in heterotrophic nitrification-aerobic denitrification systems.
Heterotrophic nitrification-aerobic denitrification (HN-AD) enables simultaneous nitrification and denitrification under aerobic conditions. However, the pathways and mechanisms by which microplastics (MPs) affect HN-AD mediated nitrogen transformation remain unclear, limiting the development of remediation strategies...
