“…Particles released by tire wear are widely considered to be important pollutants providing a source of Zn, especially in urban environments (Adachi and Tainosho 2004;Apeagyei et al 2011;Skorbilowicz et al 2020). The Cr, Ni, Cu, As, Cd, Sb, and Pb concentrations in domestic tire samples were lower than those in the finest road dust in metropolitan city of Korea (Jeong and Ra 2021a). However, the mean Zn concentration was up to 4.4 times higher in the tires of this study than in road dust (3007 mg/kg; Jeong and Ra 2021a), indicating that the Zn contamination in road dust has a greater effect from tire wear than other nonexhaust emission sources such as brake pad and asphalt wear.…”

“…In May 2014, background soil (6 samples) was collected in Busan, South Korea. Information about the road dust samples was described in Jeong and Ra (2021a).

“…Tires are made from natural rubber, synthetic rubber, metals, carbon black, and other compounds (Sommer et al 2018;Halle et al 2020). Wear particles from tires are released by traffic-related non-exhaust emissions during vehicle transportations and are one of the important sources of not only microplastic pollution (Wagner et al 2018;Järlskog et al 2020) but also heavy metal pollution in the terrestrial environments (Adachi and Tainosho 2004;Adamiec et al 2016;Jeong and Ra 2021a).…”

Background Particles from non-exhaust emissions derived from traffic activities are a dominant cause of toxic metal pollution in urban environments. Recently, studies applying multiple isotope values using the Iso-source and positive matrix factorization (PMF) models have begun to be used as useful tools to evaluate the contribution of each pollution source in urban environments. However, data on the metal concentrations and isotopic compositions of each potential source are lacking. Therefore, this study presents data on toxic metals and Cu, Zn, and Pb isotopic compositions in tires, which are one of the important non-exhaust emission sources. Findings Among the toxic metals, Zn had the highest concentration in all tire samples, and the mean concentrations were in the order of Zn > Cu > Pb > Sn > Sb > Ni > Cr > As > Cd. Ni, Zn, Sn, and Sb had higher concentrations in domestic tires (South Korea), and the Cu, Cd, and Pb concentrations were relatively higher in imported tires. The mean values of δ65CuAE647, δ66ZnIRMM3702, and 206Pb/207Pb ranged from − 1.04 to − 0.22‰, − 0.09 to − 0.03‰, and 1.1242 to 1.1747, respectively. The concentrations and isotopic compositions of Cu and Pb in the tires showed large differences depending on the product and manufacturer. However, the differences in Zn concentration and δ66ZnIRMM3702 values were very small compared with those of Cu and Pb. The relationships of the Zn concentration and isotopic composition showed that domestic tires are clearly distinguishable from imported tires. Bi-plots of Cu, Zn, and Pb isotopic compositions indicated that tires can be clearly discriminated from natural-origin and other non-exhaust traffic emission sources. Conclusions The multi-isotope signatures of Cu, Zn, and Pb exhibited different isotopic values for other non-exhaust traffic emission sources than for tires, and application of the multi-isotope technique may be a powerful method for distinguishing and managing non-exhaust sources of metal contamination in urban environments.

“…The high concentration of metals influenced the daily intake and hazard index values in humans. Children and infants are a vulnerable population and have a greater risk of experiencing health problems due to PTE exposure from the atmosphere than adults [6,55]. This is because the amount of air inhalation and other intake by children is twice that of adults (considering the intake per weight unit), and the fact that their lung function and immune systems are not yet fully developed [56].…”

Air quality deterioration is a major environmental problem in Indonesia. This study evaluated the levels and health risks of potentially toxic elements (PTEs) in Maros Regency, Indonesia. Total suspended particulate matter was collected from industrial areas for PTE (Al, Pb, Cr, Cu, Ni, As and Zn) analysis using inductively coupled plasma optical emission spectrometry (ICP-OES). Samples were collected from six critical areas in the Bantimurung region as that is where marble, cement and limestone industries are located. A calculation of the non-carcinogenic and cancer risks was performed to determine the potential health exposures in adults and children. A Monte Carlo simulation with 10,000 iterations and a sensitivity analysis was carried out to identify the risk probability and the most sensitive variable contributing to cancer risk from PTE exposure in humans. The results showed that the concentration of PTEs decreased in the order of Zn > Al > Cr > Pb > Cu > Ni > As in the wet season, and Zn > Al > Pb > As > Cr > Cu > Ni in the dry season. The hazard index (HI) value for children was 2.12, indicating a high non-carcinogenic risk for children. The total cancer risk (TCR) values in adults and children were 3.11 × 10−5 and 1.32 × 10−4, respectively, implying that both are at risk for developing cancer. The variables with the most contribution to cancer risk from As, Cr and Pb exposure in adults and children were As concentration (33.9% and 41.0%); exposure duration (ED) (34.3%) and SA (40.7%); and SA (98.7 % and 45.4%), respectively. These findings could be used as the scientific basis for public health intervention and to raise awareness of the harmful health effects of particulate bound PTEs
