Environmental health risk assessment is a new study field of environmental sciences.This study established a model for assessment of water environmental health risk.The model was applied to assess the quality of seven water supply sources in Shenzhen city.Results indicate that(1) the health risk caused by gene toxic substances ranges from 10~(-5) to 10~(-4) and caused by non-gene toxic substances ranges from 10~(-11) to 10~(-10),therefore,gene toxic substances are the pollutants of highest control priority;(2) for gene toxic substances,Cr is the highest priority pollutant in the seven water supply sources;(3) for non-gene toxic substances,ammonia is the highest priority pollutant in the seven water supply sources;(4) the total health risk caused by all pollutants for the seven water supply sources is lower than the value recommended by ICRP,but higher than the standards recommended by the Sweden Bureau of Environment Protection and the Holland Ministry of Building and Environment Protection.At present,an environmental health risk assessment is not required in environmental assessments in China.However,this paper suggests that environmental health risk assessments should be included in environmental assessments.
