Abstract

The present study reports the pH and chemical composition of rain water atfour urban sites of Delhi and one rural site away from Delhi. The collected samples were analysed for major cations (Ca, K, Mg, Na and NH3) and anions (SO4, NO3 and Cl). Data showed very high pH and Ca concentration at ruralsite which indicated the direct influence of crustal sources on rain water. It was estimated that a significant fraction of SO4 in rain water is contributed by crustal sources in this region. The association of high pH and high crustal SO4 suggested that crustal SO4 is not responsible for acidity or lowering the pH of rain water in India. Ion balance and conductivity balance for data qualify assessment was observed to be within USEPA recommendedlimits. (C) 2000 Elsevier Science Ltd. All rights reserved.
