Due to these products can be a potential source of toxic and carcinogenic elements, this study was carried out for analysis and health risk assessment of Zn and Cd in some commercial fruit juices marketed in Hamedan City in 2015.
After purchase and prepare of 16 samples of fruit juices, the concentrations of elements were determined using ICP-OES and health index was obtained. All statistical analyses (Shapiro-Wilk test and One-Sample t-test) were performed using the SPSS v.20 statistical package.
The maximum mean concentrations of Zn and Cd in fruit juice samples were 0.30±0.12 and 0.40±0.10 mg/l, respectively. Also the mean concentration of Cd in samples was upper than WHO and EPA maximum permissible limits (MPL). The results of HI showed that the HI for children and adult were 0.0011 and 0.00023, respectively for Zn, and for Cd were 0.36 and 0.077, respectively for children and adult and less than 1 for both analyzed elements.
