Correction to: Health risk assessment on human exposed to heavy metals in the ambient air PM10 in Ahvaz, southwest Iran
Heavy metals (HM) are one of the main components of urban air pollution. Today, megacities and industrial regions in
southwest of Iran are frequently suffering from severe haze episodes, which essentially caused by PM10-bound heavy
metals. The purpose of this study was to evaluate the health risk assessment on human exposed to heavy metals
and Zn) in the ambient air PM10 in Ahvaz, southwest Iran. In this study, we estimated healthy people from the following
scenarios: (S3) residential site; (S2) high-traffic site; (S1) industrial site in Ahvaz metropolitan during autumn and winter.
In the current study, high-volume air samplers equipped with quartz fiber filters were used to sampling and measurements
of heavy metal concentration. Inductively coupled plasma optical emission spectroscopy (ICP-OES) was utilized for
detection of heavy metal concentration (ng m−3
). Also, an estimate of the amount of health risk assessment (hazard index)
of Cr, Ni, Pb, and Zn of heavy metal exposure to participants was used. Result of this study showed that the residential and
industrial areas had the lowest and the highest level of heavy metal. Based on the result of this study, average levels of
heavy metal in industrial, high-traffic, and residential areas in autumn and winter were 31.48, 30.89, and 23.21 μg m−3 and
42.60, 37.70, and 40.07 μg m−3
, respectively. Based on the result of this study, the highest and the lowest concentration of
heavy metal had in the industrial and residential areas. Zn and Pb were the most abundant elements among the studied
PM10-bound heavy metals, followed by Cr and Ni. The carcinogenic risks of Cr, Pb, and the integral HQ of metals in PM10
for children and adults via inhalation and dermal exposures exceeded 1 × 10−4 in three areas. Also, based on the result of
this study, the values of hazard index (HI) of HM exposure in different areas were significantly higher than standard. The
health risks attributed to HM should be further investigated from the perspective of the public health in metropolitans. The
result of this study showed increasing exposure concentrations to heavy metal in the studied scenarios have a significant
potential for generating different health endpoints, while environmental health management in ambient air can cause
disorders in citizenship and causing more spiritual and material costs
