摘要
通过现场采样分析,对潮州市四个主要工业区冬季大气中的二氧化硫和二氧化氮的含量及时间分布进行了研究.结果表明,潮州市四个工业区冬季大气中二氧化硫的浓度范围在0.08-0.46 mg/m3之间,平均为0.28 mg/m3;二氧化氮浓度范围在0.02-0.16 mg/m3之间,平均为0.08 mg/m3.工业区二氧化硫和二氧化氮最高浓度范围主要集中在每天12∶00-15∶00.以《环境空气质量标准》(GB3095—1996)作为评价标准,计算出各工业区大气的单因子和综合污染指数.结果显示,各工业区大气均已受到不同程度的污染.工业区大气二氧化硫和二氧化氮的主要来源是企业燃料废气的排放和汽车尾气的污染.
The temporal and spatial variations of atmospheric SO2 and NO2 in winter in four main industrial areas of Chaozhou City were studied. The result showed that the concentrations of SO2 in industrial areas were in the range of 0.08 -0.46 mg/m3 and the NO2 was 0.02-0.16 mg/m3 In addition, the highest concentra- tions of SO2 and NO2 was appeared during 12：00 to 15：00. According to the atmospheric environmental quality standards （GB3095--1996）, the status of atmospheric pollution by SO2 and NO2 was evaluated by using single factor pollution index and integrated pollution index. The results revealed that the atmosphere of industrial areas was polluted by SO2 and NO2 to a certain extent. The main sources of SO2 and NO2 in atmosphere of industrial districts were industrial pollutant discharge and vehicle emission.
