“…The total HQ of studied vapour in studied land uses account for more than 80% of the HI value. In the case of children, inhalation of mercury vapour is the major path of exposure in all of the exposure pathways, which was compatible with Fang et al (2011) and Sun et al (2013). It can be observed that children are more likely to be exposed through hand-to-mouth transfer.…”

“…It is apparent that the increase of contact rate and inhalation and subsequently vapour exposure can result in the non-carcinogenic harmful special impacts to the tissues of children. Exposure to street dust in large amounts/dose by children may also cause non-carcinogenic results, as reported for other investigations (Ferreira-Baptista and De Miguel 2005;Sun et al 2013;Zhang et al 2014). Analyses indicated that the HI value for Hg in each sample type for children and adults, showed that daily vapour inhalation and ingestion of street dust were 0.55 and 0.21, therefore, lower than the safe level (=1).…”

“…The mean value of RS was greater than the other types of land-use as shown in (Table 2). It is obvious that fuel combustion is one of the main important Hg sources (Sun et al 2013;Tian et al 2010), which accounts for about 20% of the total anthropogenic Hg emission in the studied city (Statistic Bureau of Wuhan, 1990Wuhan, -2011. Hg concentration in Ahvaz street dust is high in comparison to many other cities in the world (Fig .4).…”

“…Mercury in dust collected from the streets can easily enter the human body and bloodstream during inhalation, dermal contact, and ingestion (Wei et al 2015). High levels of Hg cause adverse effects on brain, nervous system, gingivitis tremors, liver, and heart muscle (Farzin et al 2008;Sun et al 2013). The main origins of Hg in the environment are natural and anthropogenic sources (Chen et al 2010;Solgi et al 2014).…”

Mercury as a toxic element and its associated health hazard has been an important topic of research for urban pollution for many years. In this paper, the spatial distribution, pollution assessment, and health risk associated with Hg in roadside dust 96 street dust samples, representing differing land uses have been investigated. Land uses included residential areas (RA), industrial areas (IA), public gardens (PG), roadside areas (RS) and suburban areas (SA) in the city of Ahvaz, Iran were investigated. Compared with other cities, the concentration of Hg in Ahvaz was considerably higher with a mean value of 2.53 mg.kg . Residential areas exhibited higher Hg in street dust than other areas, as demonstrated by spatial mapping illustrating hot-spots associated with old urban areas with high residential density, high volume traffic of roadside areas, and industrial districts: including oil-drilling activities, steel smelting related industries, and small industrial towns around Ahvaz. However, Hg concentrations in street dust near to the public gardens (PG) and suburban areas (SA) were not at elevated levels compared other land uses investigated in this study. A health risk assessment model of non-carcinogenic effects was evaluated for both children and adults. The HQ values also revealed that the main exposures route for children and adults decreased as follows: vapour>ingestion> dermal contact> inhalation. The Hazard Index (HI) in each area is less than the safe level (HI≤1) for children and adults, but higher for children. The HI value decrease as the following order: RS>IA>RA>SA>PG, which indicates potentially serious health hazards for children in the study areas.

Urban dust has been contaminated with toxic heavy metals from various diffused sources. On August 28, 2019, the compact fluorescence lamp (CFL) factory that generates light for Rang Dong Light Source and Vacuum Flask in Hanoi City in Vietnam was accidentally fired. The assessment for Hg contamination and its human health impact 2 months after the incident was conducted in autumn 2019. The heavy Hg pollution is still found near CFL. Additionally, localized Hg pollution by air and wind direction was identified at sites in the northeast direction from CFL. Namely, in the area located downstream of the southwest monsoon wind, Hg had a trend higher than other directions. The hazard quotient (HQ) and the hazard index (HI) were evaluated by four routes of Hg exposure pathways. The HI values for children and adults in the most polluted site (Site 15) were 0.968 and 0.468, respectively. This meant that children who lived around this site and commuted to schools were the most at risk regarding the potential adverse health effects of Hg in street dust around the polluted areas. This study also showed that Hg levels were affected by wind direction and that the higher Hg levels in the most polluted sites resulted from the wind flow to the sites. This study revealed that street dust may be a useful tool for the assessment of human and environmental health.

The two primary sources of street dust are deposition of previously suspended particles (atmospheric aerosol) and displaced urban soil. This street dust can carry pollutants, including harmful heavy metals such as cadmium (Cd), mercury (Hg), lead (Pb), zinc (Zn), and other metals (Hwang et al., 2016) and affect both the urban environmental quality and human health. Several studies showed that these heavy metals were found in urban street dust at different levels (Aguilera Othman & Latif, 2020;Zhang et al., 2014). The street dust can pose potential health effects of metals upon exposure through inhalation, ingestion, and dermal contact. Residents easily come into contact with street dusts, and children are the most affected due to the hand-to-mouth activities (Zheng et al., 2010).Meanwhile, Hg is a ubiquitous environmental toxicant that can cause various adverse health effects in humans, especially children (Meza-Figueroa et al., 2007).
