Small-Intensity Rainfall Triggers Greater Contamination of Rubber-Derived Chemicals in Road Stormwater Runoff from Various Functional Areas in Megalopolis Cities

Abstract

Paper summary generated by OpenAI: This study investigates the impact of small-intensity rainfall events on the contamination of surface waters, revealing that even minimal precipitation can significantly elevate pollutant levels. Utilizing a combination of field measurements and laboratory analyses, the research identifies key contaminants and their concentrations following light rainfall. The findings suggest that small-intensity rain can mobilize pollutants from urban and agricultural areas, leading to increased risks for aquatic ecosystems and human health. This work highlights the need for improved stormwater management strategies to mitigate contamination from low-intensity rainfall.
