摘要
造纸行业是中国支柱产业之一,其造成的污染也非常可观,尤其是邻苯二甲酸二异丁酯污染。邻苯二甲酸二异丁酯不但会破坏土壤环境的生态平衡,也会威胁人体的健康水平,故提出造纸厂土壤中邻苯二甲酸二异丁酯的污染特征及风险评估方法研究。深入分析邻苯二甲酸二异丁酯的组成特征,以此为基础,以多种检测设备为工具,获取邻苯二甲酸二异丁酯污染水平、垂直特征,即随着检测位置与造纸厂距离、土壤垂直深度的增加,邻苯二甲酸二异丁酯浓度呈现逐渐下降的趋势。利用熵值法评估邻苯二甲酸二异丁酯的生态风险,制定生态风险等级判定规则,构造邻苯二甲酸二异丁酯人体健康风险评估公式,并制定人体健康风险等级判定规则,从而实现了邻苯二甲酸二异丁酯的污染特征分析及风险评估。实验结果显示:应用提出方法获得的邻苯二甲酸二异丁酯污染水平、垂直特征与实际结果保持一致,邻苯二甲酸二异丁酯生态风险、人体健康风险评估结果与实际结果相同,充分证实了提出方法应用效果较佳。
The paper industry is one of the pillar industries in China,and its pollution is also very considerable,especially diisobutyl phthalate pollution.Diisobutyl phthalate not only destroys the ecological balance of the soil environment,but also threatens the health level of human body.Therefore,the pollution characteristics and risk assessment methods of diisobutyl phthalate in paper mill soil were studied.Based on the in-depth analysis of the composition characteristics of diisobutyl phthalate,the horizontal and vertical characteristics of diisobutyl phthalate pollution were obtained by using a variety of detection equipment as a tool.That is,with the increase of the distance between the detection location and the paper mill and the vertical depth of the soil,the concentration of diisobutyl phthalate showed a gradual decline trend.The entropy method was used to evaluate the ecological risk of diisobutyl phthalate,the ecological risk level decision rules were formulated,the human health risk assessment formula of diisobutyl phthalate was constructed,and the human health risk level decision rules were formulated,so as to realize the pollution characteristics analysis and risk assessment of diisobutyl phthalate.The experimental results show that the contamination level and vertical characteristics of diisobutyl phthalate obtained by the proposed method are consistent with the actual results,and the ecological risk and human health risk assessment results of diisobutyl phthalate are the same as the actual results,which fully confirms the better application effect of the proposed method.
