摘要: Abstract The present study reports the pH and chemical composition of rain water at four urban sites Delhi one rural site away from Delhi. collected samples were analysed for major cations (Ca, K, Mg , Na NH4) anions (SO4, NO3 Cl). Data showed very high Ca concentration which indicated direct influence crustal sources on water. It was estimated that a significant fraction SO4 in is contributed by this region. association suggested not responsible acidity or lowering India. Ion balance conductivity data quality assessment observed to be within USEPA recommended limits.
