鞍山大气中有机氯农药的污染特征研究

The Present Pollution Study of Organochlorine Pesticides in Air in Anshan

布设鞍钢工业区6个点位,周边2个点位,居民区2个点位和千山对照点等11个点位,分别在采暖期和非采暖期测定大气中有机氯农药的含量,掌握了鞍山市大气中有机氯农药空间和时间变化趋势。全年有机氯农药各组分和ΣOPC浓度最高的功能区均为工业区周边,最低的功能区是千山对照点,六六六、滴滴涕和ΣOPC浓度变化趋势为工业区周边>工业区>居住区>千山对照点,全市各功能区采暖期有机氯农药各组分和ΣOPC总浓度均高于非采暖期。

For monitoring effectively the content of organochlorine pesticides in atmosphere during heating and non-heating period,six spots were emplaced in Anshan Iron and Steel Industrial Area,two spots around it,two spots in residential area and Qianshan control spot were also emplaced,there were 11 spots totally,mastered the space and time trend of organochlorine pesticides in the Atmosphere of Anshan city.The organochlorine pesticides component and the concentration of ΣOPC in atmosphere around Industrial Area was the maximum functional area,and Qianshan control spot was the minimum functional area,the change trends of HCH,DDT and ΣOPC component concentration are around area industrial zone residential area the control spot.The organochlorine pesticides component and the concentration of ΣOPC in heating period were higher than the non-heating period.
