Analysis of metal content in soils near abandoned mines of Bashkir Trans-Urals and in the hair of children living in this territory

Biomonitoring of Trace Elements in Hair of Schoolchildren Living Near a Hazardous Waste Incinerator—A 20 Years Follow-Up

“…In contrast, Hg concentrations in children from Tarragona County were lower than those found in other Spanish studies focused on assessing urban and industrial/mining areas [26,46]. The current Mn values were lower than elsewhere, differing notably from those found in Sardinia (Italy) and Russia [34,35,37]. In contrast, higher Ni levels were found when our data are compared with those of other studies, excepting those reported by Xie et al [30] in Shaoguan Guangdong (China) and Evrenoglou et al [14] in Athens (Greece).…”

“…In contrast, higher Ni levels were found when our data are compared with those of other studies, excepting those reported by Xie et al [30] in Shaoguan Guangdong (China) and Evrenoglou et al [14] in Athens (Greece). In turn, Pb levels were higher than those found in hair of children living in some mining, volcanic, sub-urban and urban areas [14,26,34,36,47] but lower than values from children living near certain mining zones, as well as near to toxic waste disposal sites and cement plants [11,30,34,35,37]. The individual characteristics of the geographic areas where the children live would probably be the responsible of the observed variability in Ni and Pb levels among studies.…”

“…This kind of correlations has been previously reported in the scientific literature. In Russia, Semenova et al [34] also found a positive correlation between Pb and Mn in hair of children living in the vicinity of abandoned mines in the South Urals, while Drobyshev et al [35] reported positive correlations of Al, Cu, Fe, Ni and V, when analysing the concentrations of trace elements in children (aged 7-9) of St. Petersburg.…”

“…The concentrations of trace elements in hair of schoolchildren were compared with those of recent studies found in the scientific literature ( Table 5). Most of these investigations are focused on areas with important industrial or mining activities or even in urban zones [11,14,26,30,[34][35][36][37]46,47]. The different results might be attributed to the differences among the respective geographical areas.…”
