[Chemical characteristic of water-soluble ions in total suspended particles (TSP) at Lijiang winter time].

25 total suspended particles (TSP) samples were collected at Lijiang city from Dec 2008 to Jan 2009. Analyzed results indicated that the concentration of CU-, NO3-, SO4(2-), Na+ , NH+, K+, Mg2+ and Ca2+ were 16.00, 14.

[Effect of developing tourism on chemical characteristic of precipitation: taking Lijiang for example].

1090 precipitation samples were collected from 1989 to 2006 at Lijiang City. The analyzed results indicate that the average pH value is 6.08 at study period, which is higher than the average pH value (5.

[Analysis on chemical compositions of rainwater in summer, Lijiang City, China].

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 SO4(2-) and Ca2+, which account for 65.
