Tóm tắt

The impacts of microplastics (MPs) on greenhouse gas emissions from mangrove soil remain poorly understood. Previous studies mostly focused on the topsoil in stable inundation state, ignoring the effects of natural tidal cycle and deep soil under different soil oxygen conditions. In this study, we analyzed soil microbial communities and greenhouse gas emissions from mangrove soils across various depths and tidal conditions (by adding seawater to create different inundation durations) in response to polylactic acid (PLA) MP exposure. Results indicated that PLA MPs addition enhances CO
