Machine learning-enabled meta-analysis reveals the effect of microplastics on nitrogen removal performance in constructed wetlands and its potential mechanisms

Puntos clave

• Microplastics significantly impair nitrogen removal performance in constructed wetlands.
• The meta-analysis included data from various studies to quantify this effect.
• Analysis reveals potential mechanisms by which microplastics interfere with nitrogen processes.
• Findings suggest the need for improved wetland management to address microplastic pollution.
