Plastic particles affect N2O release via altering core microbial metabolisms in constructed wetlandsYang, X. (author), Chen, Yi (author), Liu, Tao (author), Zhang, Lu (author), Wang, Hui (author), Chen, Mengli (author), He, Qiang (author), Liu, G. (author), Ju, Feng (author)Constructed wetlands (CWs) have been proven to effectively immobilize plastic particles. However, little is known about the differences in the impact of varying sized plastic particles on nitrous oxide (N<sub>2</sub>O) release, as well as the intervention mechanisms in CWs. Here, we built a lab-scale wetland model and introduced plastic...journal article 2024
