Abstract

The authors regret 2.11.2. Estimation target hazard quotient (THQ) The health risk in the vegetable and herb consumers was calculated based on THQ. According to study of Asgari et al. (2009) (assumptions, the mean weights for urban age groups was 15–24, 25–34, 35–44, 45–54, 55–64 and 15–64 was 64, 71, 74, 74, 72, and 69 kg and rural age groups: 60, 66, 69, 68, 67 and 65 kg, respectively) (Asgari et al., 2009). THQ was calculated by equation (2) (Chien et al., 2002):[Formula presented] In this equation, EF is the frequency of exposure (365 days in year); ED, the exposure period (70 years); FIR, per capita onion consumption (g/person/day); C, concentrations of Pb and Hg in vegetables or/and herbs (μg/kg); RFD, oral reference dose (mg/kg/day); WAB, mean body weight; TA, mean exposure time (70 years). RFD for Pb and Hg is 0.0004 and 0.0003 and mg/kg-day, respectively (USEPA, 2000). Vegetable consumption per capita of Iran was estimated as 250 kg/n-year (684 g/n-d) (FAO, 2015). While THQ <1 value there is no considerable non-carcinogenic risk when THQ ≥1 value consumers are possible adverse effects (Lei et al., 2015). 2.11.3. Hazard index (HI) HI is defined as the sum of THQ of heavy metals (Fakhri et al., 2018; Fakhri et al., 2017), as it was demonstrated in Equation (3): [Formula presented] When HI < 1 value, risk is not significant, but if HI ≥ 1 value noncarcinogenic risk is possible. As well as while HI ≥ 10 value, vegetables consumers are exposed to considerable noncarcinogenic risk (Lei et al., 2015). With 2.11.2. Estimation target hazard quotient (THQ) The health risk in the vegetable and herb consumers was calculated based on THQ. According to the study of Asgari et al. (2009) based on the assumptions, the mean weights for urban age groups was 15–24, 25–34, 35–44, 45–54, 55–64 and 15–64 was 64, 71, 74, 74, 72, and 69 kg and rural age groups: 60, 66, 69, 68, 67 and 65 kg, respectively) (Asgari et al., 2009). Estimated daily intake (EDI) was calculated by equation (2) (Chien et al., 2002): [Formula presented] In this equation, C, concentrations of Pb and Hg in vegetables or/and herbs (μg/kg); EF is the frequency of exposure (350 days/year); ED, the exposure period (years); IR, ingestion rate of vegetable (g/person/day); RfD, oral reference dose (mg/kg/day); BW, body weight (kg); TAn (EF × ED), average exposure time (days). RfD for Pb and Hg is 0.0004 and 0.0003 and mg/kg-day, respectively (USEPA, 2000). Target hazard quotient (THQ) was calculated by equation (3) (Chien et al., 2002): [Formula presented] In this equation, EDI is an estimated daily intake (mg/kg-day) and RfD, oral reference dose (mg/kg-day). 2.11.3. Hazard index (HI) HI is defined as the sum of THQ of heavy metals (Fakhri et al., 2018; Fakhri et al., 2017), as it was demonstrated in Equation (4): [Formula presented] When HI ≤ 1.0, it is not likely there will be the obvious health risk, but if HI > 1.0 shows probability health risk. Also, if HI > 10, the health risk is considerable (Lei et al., 2015). The authors would like to apologise for any inconvenience caused. © 2018
