Analysis on Chemical Compositions of Rainwater in Summer, Lijiang City, China
|
Abstract:
Rainwater samples were colleted from Lijiang City,China,in 23 May-2 July,2006.Rainwater chemical compositions and sources were studied,using HYSPLIT model,ions tracer techniques,correlation and trend analysis.Total ionic concentration was dominated by SO 2-_4 and Ca 2+,which account for 65.5% and 15.6% respectively.Sort order of ions concentration is SO 2-_4>Ca 2+>Cl->NO-_3>Na+>K+>Mg 2+.Total anions concentration is higher than total cations concentration in 13 rainwater events.The ratio of SO 2-_4 to NO-_3...
