北非某地区环境因素监测分析

摘要

The main pollutants in air, ground water, soil, and the main meteorological factors such as solar radiation, air temperature, and relative humidity in North Africa area were monitored and analyzed according to Chinese national standard and monitoring and collection procedure of natural environmental factors of the natural environmental test station network of national defense science and technology. The results showed that chloride was the main atmospheric pollutants with contents of 0.412 mg/m3 (calculated in HCl) and 0.157 mg/(100 cm2· d) (calculated in Cl-); chloride and sulfate were the main pollutants in ground water,with chloride content of 25 700 mg/m3 (calculated in Cl-) and sulfate content of 42 000 mg/m3(calculated in SO42-); the total salt content in the soil was 0.3％～0.4％, which belonged to salty soil or alkali soil.%采用国家标准和国防科技工业自然环境试验网站<自然环境因素采集及监测规程>规定的方法,对北非某地区的环境状况(如大气、地下水、土壤等的主要污染物含量)及太阳辐射、温湿度等主要气象参数进行了短期综合监测.监测结果表明,氯化物是当地大气的主要污染物,监测期间瞬时法测得氯化氢质量浓度平均为0.412 mg/m3(以HCl计)、连续法测得海盐粒子累积质量浓度平均为0.157 mg/(100 cm2·d)(以Cl-计);氯化物和硫酸盐是当地水质的主要污染物,氯化物质量浓度为25 700 mg/m3(以Cl计)、硫酸盐质量浓度为42 000 mg/m3(以SO42-计);该地区土壤总含盐量为0.3%～0.4%(质量分数),属盐渍土或盐碱地.
