目前国内建设用地调查、风险评估、修复及效果评估主要针对人体健康,未考虑地块土壤异味的环境风险影响.本研究以某废弃农药厂为例,开展土壤异味调查评估、治理修复及效果评估工作.地块土壤主要异味物质包括乙苯、苯酚、间二甲苯、对二甲苯、苯乙烯、甲苯、邻二甲苯.基于暴露模型计算土壤异味控制值,结合土壤样品仪器分析结果,初步确定异味控制范围 5635.88 m2;结合土壤样品嗅觉分析结果,综合确定土壤异味控制范围 6885.80 m2.修复后土壤仪器分析和嗅觉分析结果均符合控制目标,判定土壤异味修复效果评估合格.本研究形成了建设用地土壤异味调查评估、修复及效果评估方法流程,可为其他地块开展相关工作提供参考.
The investigation,assessment,remediation,and verification of remediation of soil odor in a pesticide-contaminated site
Current investigation,risk assessment,remediation and verification of remediation on soil contamination of land for construction in China primarily focus on human health,neglecting the environmental risks posed by soil odor.This study,a defunct organophosphorus pesticide factory was selected as a case,conducts an investigation,assessment,remediation,and verification of remediation of soil odor.The main odoriferous substances in the soil of the site include ethylbenzene,phenol,m-xylene,p-xylene,styrene,toluene,and o-xylene.Based on exposure modeling,the soil odor control value is calculated,and combined with the results of instrumental analysis of soil samples,an initial odor control area of 5635.88 m2 is determined.By integrating the results of olfactory analysis of soil samples,the comprehensive odor control area is determined to be 6885.80 m2.After remediation,both instrumental and olfactory analysis results of the soil meet the control targets,indicating that the odor remediation of the soil is deemed effective.This study establishes a methodological process for the investigation,assessment,remediation and effectiveness evaluation of soil odor in construction land,which can serve as a reference for similar work on other sites.
