某污泥倾倒农田污染事件环境损害鉴定评估研究
Study on Identification and Assessment of Farmland Pollution Environmental Damage by Dumping Sludge

本文以某污泥非法倾倒至农田污染事件为例，根据相关环境损害鉴定评估技术规范和流程，以现场踏勘、人员访谈、土壤及地下水污染状况调查等为基础，开展环境损害确认、环境损害实物量化以及环境损害恢复方案筛选。结果表明，此次污泥倾倒农田污染事件导致评估区内0~0.5 m表层土壤和0.5~1.0 m深层土壤受到环境损害，1.0~1.5 m深层土壤和地下水未受到环境损害。受损害土壤的重金属和矿物油检测结果高于环境基线水平，但低于相关标准限值，无环境污染风险，生态环境损害数额合计42.98万元。
Taking an instance of illegal sludge dumping onto farmland as an example, following the relevant technical specifications and processes for environmental damage identification and assessment, it conducts environmental damage confirmation, quantification of environmental damage, and selection of environmental damage recovery plans based on on-site inspections, interviews with personnel, and investigations into soil and groundwater pollution. The results indicate that the sludge dumping incident caused environmental damage to the surface soil (0~0.5 m) and subsurface soil (0.5~1.0 m) within the assessed area, while the deeper soil (1.0~1.5 m) and groundwater were not affected. The detection results of heavy metals and mineral oil in the damaged soil were higher than the environmental baseline levels but below the relevant standard limits, indicating no risk of environmental pollution. The total amount of ecological and environmental damage was estimated at 429,800 RMB.
