Chemistry of rain in central India

摘要: The south-western Arabian summer monsoon loaded with local and distant pollutants causes heavy rainfalls in the central region of Indian continent. chemistry rain water country (lies between 17° 24°N latitudes, 80°17' 84° 11'E longitudes at altitude >300 m) during hydrological years 1995 to 1997 is described A total 800 events twelve sites, i.e., Raipur (during 1995-1997), Korba, Bilaspur, Kanker, Janjgir, Raigarh, Chirmiri, Bhatapara, Pithora, Gariyaband, Dallirajhara Ambikapur India 1995) were occurred, from which 477 collected a polyethylene bucket kept over roof houses. chemical composition for ions, H + , Na K Ca 2+ Mg NH 4 SO 2- NO 2 3 - Cl F I ionic balance, pH conductivity samples determined. concentration, flux, deposition patterns trends ions their sources are described. sulphate predominating ion primary source acid India. Most storms occur on its areas. these mostly acid, especially season, probably due blown less amount soil dust higher humidity.
