Besides that, the previous studies find that the hazard quotient (HQ) maximum values at Pb/Zn smelting locations in Guangdong, Sichuan, Guizhou, Guangxi, Jiangsu, Hunan, Liaoning, and Zhejiang were greater than 10, while the mean and median HQs in Sichuan, Fujian, Guangxi, and Zhejiang were...
The HI was calculated as the sum of HQs from the different pathways. HI was calculated using Equation (15). The reference dose (RfD) for non-carcinogenic metals is shown in Table 3. HQois = OISERnc × Csur R f Do × SAF (12) Int. J. Environ. Res. Public Health 2016, 13, 832...
