太原市工业区大气中TSP浓度及元素成分分析

Analysis on TSP Concentration and Elemental Constituents in Industrial Area Atmospheric Environment of Taiyuan City

采用校正空白称量法对太原市工业区大气中TSP浓度进行了测定分析,对该区大气TSP浓度随时间变化的规律、超标情况及污染特征进行了研究,同时测定了TSP中Cr、Pb等12种元素的含量。结果表明:该工业区大气中TSP浓度在每月中旬出现最大值,月变化从7月至12月呈上升趋势,且超标情况严重,有65％的样品超标,最高超标倍数达4.12倍。Cr、Pb等12种元素的平均含量都高于对照区,是对照区的2.23-74.2倍,表明该工业区已受到了严重污染,并提出了防治对策。

TSP concentration in atmospheric environment of Taiyuan industrial area has been determined with the method of correct blank weight, and the content of 12 metallic elements in TSP were also determined, and TSP concentration varying with time, TSP exceed standard ratio and pollution characteristics were also studied. The result showed that the maximum value occurred in the middle ten days of every month, and the tendency of TSP concentration went up from July to December, which was 65% of total samples exceeded the standards, the highest value reached 4.12 fold, and the average content of 12 metallic elements always exceeded the controlled area(the campus), being 2.23 to 74.2 fold of controlled area. This indicated the industrial area was polluted seriouly, and the preventive countermea-sures were also proposed.
