Health Risk Assessment for Heavy Metals in Natural Cold-Bicarbonated Mineral Water, Wudalianchi

Natural cold-bicarbonate mineral water is rich in varies of trace elements in Wudalianchi, northern China. In this paper, heavy metals’ (HMs) concentrations were measured. Furthermore, the health risk assessment of risk index (RI) and hazard quotient (HQ) was calculated. According to the dates, the average risk order were Ni>Fe>Mn>Ba>Cu>Hg>Zn for South Spring and Ni>Fe>Mn>Hg>Ba>Cu>Zn for North Spring. The risk level was lower than the maximum acceptable value recommended by International Commission on Radiological Protection (ICRP) 5.0×10-5a-1. The HQ values of Ba, Cu, Hg and Zn were <1, but the HQ values of Ni, Mn and Fe were >1. The results indicated that cold-carbonated mineral water wasn’t potable water for daily drinking.
