英文摘要	A systematic investigation and greater understanding of the precipitation chemistry with respect to the altitude gradient in mountainous areas is necessary to promulgate the detrimental consequences of pollution on various ecosystems. Studies on the chemical compositions of wet precipitation were performed on the northern slopes of Mt. Taibai, Qinling Mountains, one of the highest mountains in East China, from different lateral monitoring stations (i.e., with elevations between 610 and 3511 m) over the period from 2011 to 2014. All samples were analyzed for major ions (SO42-, NO3- Cl-, F-, NH4+, Ca2+, Mg2+, Na+, and K+). The results revealed that the total ion concentration and average measured ions concentrations in precipitation decreased with the increase of altitude in the Mt. Taibai. The concentrations of precipitation ions are always higher during non-monsoon period compared to the monsoon period, except for the altitude above 3000 m a.s.l. A negative gradient of approximately -6.58 and -34.04 mu eq.L-1/100 m of the total ion concentrations was obtained during the monsoon and the non-monsoon period, respectively. NHS' was the most promising species for completely neutralize the acidity at the altitude of 500-1000 and 3000-3500 m a.s.L, while Ca2+ was the potential species for completely neutralize the acidity at the altitude of 1000-3000 m a.s.l. The crustal-derived species (Ca2+, Mg2+, Na+, K+ and Cl-) exhibit statistically significant correlations with each other at the altitude from 500 to 2500 m a.s.l. (r = 0.31-0.91). The contributions of sea salt source and terrestrial source to SO42- and NO3- are small, which is mainly contributed by human activities. For Na+, Mg2+, and K+, there was both the contribution of the terrestrial and human activities. The inorganic pollutants (major ions such as the SO42-, NO3-, Cl-, F-, NH4+, Ca2+, Mg2+, Na+, and K+) in the Mt. Taibai appear to be derived from the regional crustal dusts, anthropogenic emissions, and the long-range transported from the sea.
