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.
对恒河 35 公里河段的大气沉降（AD）和水化学的调查表明，尽管 AD 的 N:P 化学计量比没有变化，但随着时间的推移，AD-NO₃⁻、AD-NH₄⁺和 AD-PO₄³⁻的浓度增加了 1.4-2.0 倍。河水中溶解无机氮（DIN）的浓度与 AD-NO₃⁻和径流水 DIN 呈显著正相关。同样，河水中的可溶解性反应磷（DRP）与 AD-PO₄³⁻和径流水 DRP 呈显著正相关。研究表明，AD 已成为恒河 N 和 P 输入的重要来源。
