资兴市柑桔生产基地大气质量现状及评价

Status and Evaluation of Air Quality of the Base of Mandarin Orange of Zixing City

根据柑桔生产基地的地理位置和气象条件，在基地内设置3个具有代表性的采样点，进行大气采样分析及评价。结果表明，各点位二氧化硫（SO2）、氮氧化合物（NOx)、总悬浮物（TSP）、氟化物（F^-)单项污染指数均小于1．0，综合污染指数均小于0．6。大气环境质量达1级清洁水平，适宜发展绿色食品。

According to the geographical position and the weather conditions of the mandarin orange base, three representative sample-collecting spots are set up to analyze and evaluate the atmosphere. The results show as follows:the individual contamination index of SO 2, NO x, TSP and F - at the three spots is below 1 0 and the synthesize pollution index is below 0.6 separately. So the air environmental quality reaches the first clean level and it is fit to develop organic food.
