Inhalation Health Risk Assessment of Some of Heavy Metals for Kerosene Samples in Iraq Market

In this study, five heavy metals (Zn, Fe, Pb, Cu, and Cd) concentrations were measured in samples of kerosene (locally only) that collected from different of warehouses oils in Iraq. The measurements have been done using Atomic Absorption Spectrophotometer. Non-cancer risks such as the chronic daily inhalation intake (CDIinh), a Hazard Quotient (HQ), and Hazard Index (HI) as well as Cancer Risks (CR) due to inhalation of heavy metals in the kerosene samples were calculated. The results show that, the average values of concentrations in unit ppm (mg/kg) belonging to Zn, Fe, Pb, Cu, and Cd in kerosene samples were 8.14±1.74, 0.127±0.025, 0.017±0.007, 0.15±0.064, and 0.360±0.022, respectively. While, the average value of Hazard Index (HI) due to all heave metals in the present work was 0.721± 0.16. Also, the average value of Total Cancer Risk (TCR) due to Cd and Pb were 1.12E-03±4.4E-04. When comparing the results of inhalation health risk, the present work with Worldwide average, we found that the most samples of kerosene samples are safe for using.
