Comparative study on the growth and phytoremediation efficiency of key submerged plants and nitrogen dynamics under varying ammonia nitrogen concentrations

Key Points

• Submerged plants exhibit varying phytoremediation efficiency based on ammonia nitrogen concentrations, indicating significant adaptive responses.
• A maximum of 50% growth increase observed in submerged plant species at optimal nitrogen levels, revealing crucial thresholds.
• Analysis of nitrogen dynamics highlights the role of submerged plants in improving nitrogen removal efficiency from aquatic systems.
• Calls for further investigation into long-term effects of ammonia nitrogen on aquatic ecology and plant health.
