摘要 | A total of 30 precipitation samples were collected at a remote site of Qinghai Lake in the northeastern Tibetan Plateau, China, from June to August 2010. All samples were analyzed for major cations (NH4+, Na+, K+, Ca2+, and Mg2+) and anions (F-, Cl-, NO3-, and SO42-), electric conductivity (EC), pH, dissolved organic carbon (DOC), and oxygen isotopic composition (delta O-18). The volume-weighted mean (VWM) values of pH and EC in the precipitation samples were 7.2 and 19.0 mu s cm(-1). Ca2+ was the dominant cation in precipitation with a VWM of 116.9 mu eq L-1 (1.6-662.9 mu eq L-1), accounting for 45.7% of total ions in precipitation. SO42- was the predominant anion with a VWM of 32.7 mu eq L-1, accounting for 47.1% of the total anions. The average precipitation DOC was 1.4 mg L-1, and it shows a roughly negative power function with the precipitation amount. The values of delta O-18 in the rainwater in Qinghai Lake varied from -13.5 parts per thousand to -3.9 parts per thousand with an average of -8.1 parts per thousand. The enrichment factor analysis indicates that crustal materials from continental dust were the major sources for Ca2+ in the precipitation samples. The high concentration of Ca2+ in the atmosphere played an important role in neutralizing the acidity of rainwater in Qinghai Lake area. Cluster analysis of air-mass trajectories indicates that the air masses associated with northeast and east had high values of NH4+, SO42-, and NO3-, whereas large Ca2+ loading was related to the air mass from west. |
