<fluoride \(F\)>Hg, within Pb accounting for 44.77%, fluo-ride \(F\) accounting for 34.30% and Hg accounting for 20.92%. The average individual carcinogenesis annual risk of Cr\(VI\) is the greatest, achieving 8.9110-4/a. The ranking of risk value due to chemical carcinogen by rural drinking water of Yaan is Cr6+>As>Cd, within Cr6+ accounting for 91.12%, As accounting for 5.89% and Cd accounting for 3.00%. Based on this, the strategy and measures of the health risk management are put forward. This study has worked efficiently in practice. Compared with the same kind of methods which have been found, the paper has the outstanding results for the health risk assessment of the rural drinking water safety.)/SourceModified(D:20090819111838)/Author(Fuquan NI, Guodong LIU, Huazhun REN, Shangchuan YANG, Jian YE, Xiuyuan LU, Min YANG)/CreationDate(D:20090819191858+08'00')>>
