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.展开更多
