Atmospheric Deposition: An Important Determinant of Nutrients and Heavy Metal Levels in Urban Surface Runoff Reaching to the Ganga River

Environmental Fate and Effects of Road Run-Off

“…Regarding metals, in addition to the known risks related to metals associated with automotive traffic, new information is available on additional routes of transport and the presence of emerging metals of concern being associated with road runoff. Siddiqui and Pandey ( 2022 ) demonstrated that the levels of nutrients and metals in atmospheric deposition and runoff from three cities draining to India’s Ganga River were highly correlated and that most metals were present at concentrations higher than previously reported, particularly during first flush. Lerat-Hardy et al ( 2022 ) conducted high-frequency sampling to determine the concentrations of metals, both trace (e.g., copper, zinc) and rare earth elements (e.g., lanthanum, cesium) in runoff from France’s longest urban highway.…”
