    Abstract:
    OBJECTIVE: To analyze the level of metal/metalloid elements and assess the health risk in drinking water in Dongcheng District of Beijing. METHODS: From 2018 to 2020, 10 kinds of metal/metalloid elements(Fe, Mn, Cu, Zn, Al, Pb, Cd, Ni, As and Se)in drinking water were detected by inductively coupled plasma-mass spectrometry(ICP-MS). The concentration of these metals were compared with the hygiene standards of drinking water. The health risk assessment model was applied from the USEPA. RESULTS: The concentration of 10 kinds of elements met the hygiene standards in all of the drinking water samples except that the zinc concentration of one sample exceeded the limit. The concentration of Al, Fe and Zn in drinking water was tens of μg/L. The concentration of Cu, Mn, Ni and Se was 1-2 μg/L or even lower. The concentration of As, Cd and Pb was basically less than 1 μg/L. The monthly average concentration of Al in drinking water showed a trend of increasing, and then decreasing in a year. The concentration of Zn decreased year by year. The 10 kinds of elements had not shown significant difference in the two water supply modes of municipal pipe network terminal water and secondary water(P>0.05). The total carcinogenic risk of elements through drinking exposure was 3.53×10~(-5). The carcinogenic risk of As was higher than that of Cd. The total non-carcinogenic risk was 9.75×10~(-8). The order of non-carcinogenic risk was: As>Se>Ni>Zn>Al>Pb>Fe>Cu>Mn>Cd. The total health risk was 3.54×10~(-5). CONCLUSION: The 10 kinds of metal/metalloid parameters of drinking water in Dongcheng District of Beijing met the hygiene standards. According to USEPA evaluation standard, the health risk assessment of elements in drinking water was acceptable.
