对恒河沿岸沿着35 km的大气沉积物（AD）和水化学的调查表明，尽管AD的N：P化学计量没有变化，但AD-NO3-、AD-NH 4+和AD-PO 43-随时间增加超过1.4-2.0倍。河流溶解态无机氮（DIN）浓度与AD-NO3-和径流DIN呈显著正相关。河流中溶解活性磷（DRP）与AD-PO 43-和径流DRP呈显著正相关。研究表明，AD已成为恒河氮、磷输入的重要来源。
Investigations on atmospheric deposition (AD) and water chemistry along a 35 km stretch of Ganga River indicated that although N:P stoichiometry of AD did not change, there were over 1.4–2.0 fold increase in AD-NO3−, AD-NH4+ and AD-PO43−overtime. Concentration of dissolved inorganic-N (DIN) in river showed significant positive correlations with AD-NO3− and runoff DIN. Similarly, dissolved reactive-P (DRP) in river showed significant positive correlation with AD-PO43− and runoff DRP. The study shows that AD has become an important source of N and P input to Ganga River.
