Organophosphate triesters and diesters in surface waters and sediments of an urbanized river in Eastern China: Spatial patterns and ecological implications

Key Points

• Organophosphate diesters and triesters are prevalent in urban river sediments, indicating potential ecological impacts.
• Concentrations of organophosphate compounds in surface waters show significant variation by location, with some sites exceeding safety thresholds.
• Assessment of water and sediment samples provides insights into pollution levels and their spatial distribution.
• Findings highlight the need for pollution management in urban waterways to mitigate ecological risks.
