摘要
为了解山西省大气降水水质状况、主要污染物及区域分布规律,山西省水文部门于1984年开始对大气降水进行监测。在全省9个地市布设测点,分别为:太原市、大同市、长治市、榆次市、临汾市以及吕梁、忻州、阳泉、运城地区。监测项目为H+、电导率、Ca2+、Mg2+、K+、Na+、NH4+、SO42-、NO3-、Cl-、CO32-、HCO3-、F-。结果表明,除吕梁、忻州地区外,山西省各地市均有酸雨发生,但酸雨发生的频率不高,全省年平均为3.3%;酸雨的酸性程度也不高,对生态可造成明显影响的降水次数不多;山西省酸雨为典型的硫酸型,酸雨中硫酸与硝酸的质量浓度比值远高于全国平均值。
To explore the water quality of atmospheric precipitation, main pollutants and their regional distribution law, atmospheric precipitation was monitoring from 1984 by hydrology management department in Shanxi. Monitoring sites were located in nine cities, they were Taiyuan, Datong, Changzhi, Yuci, Linfen, Luliang, Yizhou, Yangquan and Yuncheng. Monitoring items were H+, conductivity, Ca2+, Mg2+, K+ , Na+, NH4+, SO42-, NO3-, Cl-, CO32-, HCO3- and F-. Result indicated that each cities have acid rain except Luliang and Yizhou, but the frequency was low, was average 3.3%. The acid degree was also low. Acid rain was typical sulfuric acid type, the ratio of sulfuric acid and nitric acid was high than the national average.
