Pollution assessment and health risks evaluation of (metalloid) heavy metals in urban street dust of 58 cities in China

Pollution status and human health risk assessment of potentially toxic elements and polycyclic aromatic hydrocarbons in urban street dust of Tyumen city, Russia

“…For example, V showed the highest mean value for soils, while street dust and puddle sediments were found to be similar. When comparing the mean values of metals in street dust from Tyumen with data for street dust from 58 Chinese cities (Zhaoyong et al 2019), it may be concluded that the contents of Cu, Cd, Pb, Zn, Mn, and As were lower and the contents of Cr, Ni, and Co were higher. Higher levels of these metals in street dust from Tyumen are probably related to the industrial sources, namely, machinery and metalworking.…”

“…The pollution levels of individual PTEs and PAHs in the dust samples were evaluated using the geoaccumulation index (I geo ), introduced by Müller (1986). This method is widely used to assess not only soil and sediment pollution, but also street dust (Shi et al 2010;Trujillo-González et al 2016;Lu et al 2017;Amjadian et al 2018;Men et al 2018;Zhaoyong et al 2019). Lu et al (2017) proposed using the Nemerow pollution index (NPI) for a comprehensive assessment of street dust pollution.…”

“…At the same time, street dust particles are a source of pollutants in roadside soils (Prokof'eva et al 2017;Ró _ zański et al 2017;Pariente et al 2019), which can re-enter the atmosphere through resuspension (Jordanova et al 2014) or migrate with surface runoff and stormwater (Calvillo et al 2015;Liu et al 2016). Numerous studies are devoted to the status of various pollutants, primarily PTEs and PAHs, in street dust in some of the world's largest megacities, industrial production centres (Liu et al 2007;Saeedi et al 2012;Acosta et al 2014;Yu et al 2014;Soltani et al 2015;Bandowe and Nkansah 2016;Tang et al 2017;Men et al 2018;Cappelletti et al 2019), cities, and towns (Majumdar et al 2017;Ghanavati et al 2019;Zhaoyong et al 2019). The results of these studies have shown that accumulation of pollutants in street dust and near road environments is influenced by a wide range of factors, including population density, traffic, degree of soil sealing, age and type of automobiles, climate, and geological conditions of a particular territory (Charlesworth et al 2003;Shi et al 2010;Wei et al 2010;Zhang et al 2015;De Silva et al 2016;Trujillo-González et al 2016;Yan et al 2018).…”

Investigation of the 2018 Shiraz dust event: Potential sources of metals, rare earth elements, and radionuclides; health assessment

“…As mentioned, PTE concentrations in the settled dust samples showed high variations and the coefficient of variation was more than 0.4. Many investigations pointed out that these PTEs could have originated from industrial and traffic emissions (Abbasi et al, 2020;Zhaoyong et al, 2019;Jadoon et al, 2018;Keshavarzi et al, 2018). In general, Cu, Zn, Pb, and Cd have been observed in high traffic areas (Bem et al, 2003;Sternbeck et al, 2002;Abbasi et al, 2018;Kabata-Pendias and Mukherjee 2007).…”

Evaluating heavy metals contamination in campus dust in Wuhan, the university cluster in Central China: distribution and potential human health risk analysis

“…Moreover, surface dust mainly enters the human body through skin contact, respiration, and hand-mouth direct intake (USEPA, 2009). The average daily dose (ADD) was calculated for the three exposure pathway: ingestion, inhalation, and dermal absorption using the following formulas (USEPA, 2009;Zhang et al, 2019)…”
