Abstract:Based on the EPACMTP model and health risk assessment model developed by US EPA, a new method was set up to assesse the health risk of groundwater in hazardous waste landfill disposal, and the effectiveness of this method was studied in hazardous waste landfill site and non hazardous waste landfill site that accepted the electroplating sludge. The new developed method was effective and less parameter was needed. The non-cancer effect risk produced by target contaminants (Ni, Mn, Cr6+) was 10.20×10-4 when the electroplating sludge was put into the hazardous waste landfill site, and the risk was 0.81×10-1 when the electroplating sludge was put into the non hazardous waste landfill site. However, the non-cancer effects risk (hazard index, HI) were largely below the value accepted from the US EPA. In terms of health risk on sensitive points, this electroplating sludge could be put into the non hazardous waste landfill site.
