Background and Objective: During the last few decades, heavy metal pollution in indoor dust has been widely studied; While, the quality of the environment inside the cars has not been considered enough. Therefore, the specific objectives of this study generally include investigating the levels of selected heavy metals in the dust of private cars collected from Ahvaz city, as well as evaluating the health risk of carcinogenesis and exposure to the dust inside these cars through ingestion, inhalation, and skin absorption.
Materials and Methods: 10 cars were selected for this study. The condition of choosing the cars was not to wash the car for a week. Then, samples were collected and coded from the dust of the air conditioner filter and the cabin of each car. To determine the composition of heavy metals, spectroscopic analysis (ICP) was performed on the samples.
Results: The study of non-carcinogenic risk index (HI) in the present study indicates that the values of more than 1 and the health risk is high. The sequence of HI index values for heavy metals was obtained as Pb>Cu>Cr> Fe> Zn> Cd> Ni. Evaluated risks from different pathways in children was HQing < HQinhder while in adults follows HQingder< HQinh process. Additionally, the values of enrichment factor of the studied samples showed the maximum and minimum values for Cu (4.3) and Ni (8.3), the maximum and minimum geoaccumulation index for Fe (12.75) and Ni (1.9) and the amount of integrated pollution and pollution index were estimated to be 1.34+E27 and 2.07+E9, respectively, indicating the average range for the studied heavy metals.
Conclusion: According to this study, the risk of non-carcinogenic risk of heavy metals (except Fe and Cu) for children is estimated to be higher than that of adults. Furthermore, the investigation of the CR index for the three carcinogenic heavy metals (cadmium, chromium, and arsenic) has exceeded the safe level, which indicates ingestion and inhale as the target pathways for the worst adverse effects of heavy metals in children andadults, respectively. In the present study, the amount of heavy metals studied is more than the set standards. The results of the current study showedthe more enrichment of heavy metals in the car filter as compared with the cabin.
