Introduction: Todays, the use of biomonitoring to determine air quality is continuously increasing. Heavy metals are of interest among air pollutants due to their detrimental effects on health. The aim of the present study was to biomonitoring5 heavy metals from the ambient air of Ahvaz using lichen for 6 months from June to December 2019.
Materials and Methods: Heavy metals including arsenic, cadmium, chromium, nickel and lead were adsorbed on lichens cultivated at 26 sampling stations with residential, industrial and traffic uses in the desired locations. For each sample, cleaning, drying, extraction and digestion of the samples were performed and then the concentration of heavy metals was determined by inductively coupled plasma optical emission spectrometry (ICP-MS) with three repetitions. After that, the data was analyzed using Excel software and the non-cancer and cancer risk for adults and children from the three exposure routes of ingestion, inhalation and dermal was calculated and evaluated.
Findings: The highest concentrations of heavy metals were recorded in industrial and then traffic uses. The most important heavy metals in the ambient air in industrial use are nickel, chromium, and arsenic with average concentrations of 141, 87.27, and 10.33 mg/kg wd, respectively, and in traffic use, nickel, chromium, and cadmium with average concentrations of 87.35, 41.24, and 2.48 mg/kg wd, respectively.
Conclusion: Heavy metals affected by industrial and then traffic activities showed a potential carcinogenic risk. The potential carcinogenic risk of heavy metals for children from the route of exposure to digestion in industrial and traffic areas of Ahvaz should be considered by the authorities in order to provide management solutions and reduce the concentration of pollutants as well as reduce the exposure of residents in Ahvaz.
