A mean pH value of 5.53 was gained, and the samples' conductivity showed no linear correlation with its acidity, which did not agree to the similar work results on the Qinghai Tibet Plateau. Cl - and Na + were found to originate mainly with seasalt. The concentrations of SO 2- 4 varied from event to event. But the exSO 2- 4 concentrations remained small, which indicated less anthropogenic effect on the environment at the site.展开更多
