This article presents an application of assessing human health risk in typical city of North China plain. Combined with water quality and multi-element analysis, Pb, Cd, Cr6+, Mn, NO3 /sup>, F/sup>, and As in groundwater samples were chosen to be used for human health risk assessment of drinking water pathway and dermal contact pathway, and results show a good effect. Results indicate that (1) poor water quality is caused by salinity and hardness overstandard; (2) in noncarcinogenic risk, samples that do not pose noncarcinogenic risk only account for 28.46%; in carcinogenic risk, samples that do not pose carcinogenic risk account for 73.08%; (3) the noncarcinogenic risk in the study area decreased in the following order: NO3 /sup>>Mn>As>F/sup>>Cr6+>Cd>Pb and the carcinogenic risk of the study area decreased in the following order: As>Cd=NO3 /sup>=Mn=F/sup>=Cr6+=Cd=Pb=0, because the slop factors were not available for the other pollutants, except for As; and (4) in terms of whole study area, the main contribute order of drinking water pathway and dermal contact pathway in human body is drinking water pathway>dermal contact pathway.
