本文调查分析了锦州市、县、乡镇和普通村庄空气中苯并(a)芘的污染水平,并用相关系数说明空气中苯并(a)芘的浓度与二氧化硫的浓度呈正相关。同时,我们调查了流经市区的小凌河水中苯并(a)芘的污染水平,发现河水流经市区后,苯并(a)芘的浓度显著升高;对农家院里的井水调查,发现4.2%的井水中苯并(a)芘浓度超过饮用水标准(10ng/L)。
In this paper, the pollution levels of benzo (a) pyrene in the air of Jinzhou City, counties, townships and villages were surveyed and analyzed. The correlation coefficients indicated that the concentration of benzo (a) pyrene in the air was positively correlated with the concentration of sulfur dioxide. At the same time, we investigated the pollution level of benzo (a) pyrene in the Xiaoling River water flowing through urban areas and found that the concentration of benzo (a) pyrene increased significantly after the water flowed through the urban area; Water survey found that 4.2% of well water benzo (a) pyrene concentration exceeded the drinking water standard (10ng / L).
