CWE/38/2017 当前世界环境 0973-4929 2320 - 8031 Enviro Research Publishers CWE--5-00 Himalayan snow chemistry: Chemical composition of fresh snow samples from Kashmir valley 2 , GPO Box 726, Srinagar, 190001, India. 2007-06-30 10.12944/CWE.2.1.03 Volume 2 Volume 2 17日 Abstract

The present paper deals with variability in snow chemistry of various sites spread in six districts of the Kashmir Himalayan valley, experiencing frequent snow fall during winter ( Dec.- Feb). Chemical composition of fresh snow samples shows wide changes in pH (5.8–7.3), dissolved oxygen content (22-26 mg L-1), and total alkalinity (2-3 mg L-1). The levels ( mg L-1) of calcium (13.3– 28 ), magnesium (8-12 ), chloride (15-30), sulphate (2-8), silicate (1-4) and nitrate (1.9-3.9) differed considerably. The study makes a strong plea for in-depth investigations of snow chemistry of little-explored Himalayan region, useful for assessing the impact of environmental pollution.
