Abstract

By measuring the content of phthalate esters in different environmental media, this study analyzes the pollution situation in the region and provides scientific basis for putting forward targeted supervision and management countermeasures. 39 water samples and 36 soil samples from Jianhua district, Longsha and Tiefeng districts of Qiqihar City were taken as the research objects. The contents of six PAEs metabolites DEP, DBP, DEHP, DNOP, DMP and BBP were determined by gas chromatography. The results were expressed in median and quartile, and were statistically analyzed by Wilcoxon rank sum test. The test level was α=0.05. The results showed that three compounds DEP, DEHP and DBP were detected in clean area and four compounds DEP, DEHP, DBP and DMP were detected in polluted area. The detection content of PAEs in polluted area is different from that in clean area, and the pollution area is higher than that in clean area, with statistical significance (P < 0.05). Among the six PAEs to be detected in soil, five compounds DEP, DEHP, DBP, DMP and BBP were detected in polluted area and clean area. The detection content of PAEs in soil in polluted area is different from that in clean area, and the pollution area is higher than that in clean area, with statistical significance (P<0.05). The difference of phthalate esters in different environmental media shows that it is urgent to further strengthen the supervision and management of environmental pollutants and effectively reduce the emission and use of phthalate esters to maintain environmental quality and public health.
