Nitrogen and DOM inputs alter greenhouse gas dynamics in field scale constructed wetlands treating wastewater plant effluent: insights from core species activity

Puntos clave

• Greenhouse gases increased in constructed wetlands with nitrogen and dissolved organic matter inputs, indicating active microbial processes.
• Core species showed variable activity levels, with certain species contributing significantly to greenhouse gas emissions measured in real-time.
• Analysis of field-scale constructed wetlands was conducted over several seasons, highlighting the seasonal variability in gas dynamics.
• These findings underscore the importance of carefully managing nutrient inputs in constructed wetlands to optimize their environmental benefits.
