“…These affectations attack the systems of the human body and each of the organs in general, showing cases of neuropsychiatric affectation among children from 0 to 4 years old and a decrease in the total weighted IQ [43]. In addition, deterioration is observed in the functions of the central nervous system with neuromotor impairment and the appearance of symptoms similar to Parkinson's, the endocrine system with symptoms of renal and hepatic insufficiency and genetic alterations, mutagenic, teratogenic, and carcinogenic effects [40,44,45]. Finally, Ungureanu, E.L., and Mustatea, G., mention that contact with heavy metals can increase the incidence of antisocial behavior in children, making an alarming call for attention to organizations, given that the young population can absorb 4 to 5 times more lead and heavy metals than an adult, and thus increase the damage in the systems and organs exposed to the high concentration and bioaccumulation rates [40].…”

This article describes the validation of analytical methods for the determination of Manganese (Mn) and lead (Pb) by graphite furnace atomic absorption spectrometry (GFAAS) in human hair and nail samples. Method validation parameters such as linearity, repeatability, reproducibility, and precision were determined. In addition, the limit of detection (LOD), the limit of quantification (LOQ), and measurement uncertainty were calculated. The developed method was linear in the concentration ranges of 0.001–0.015 and 0.002–0.020 µg·L−1 of Mn and Pb, respectively. The determination coefficients obtained were greater than 0.995. The recoveries obtained after the addition of the standard concentration for the metals ranged from 84.80–107.98%, with a precision not exceeding 12.97% relative standard deviation. The calculated LOD and LOQ for Mn and Pb are within the ranges established by Commission Regulation (EU) No. 836/2011. The expanded uncertainty was estimated to be less than 9.93–6.59% for Mn and Pb. Matrix effects were also studied, finding a smooth effect in both matrices. The analysis of 30 samples of each type revealed the presence of Mn in 30 and Pb in 13 samples. Overall, the proposed validation method was considered optimal for the determination of Mn and Pb.

“…Researchers in many countries have carried out studies to assess metal exposure levels in different target populations. These studies have formed the basis for further metal exposure assessments in humans and other toxicology studies [ 19 , 21 , 22 ]. In the field of environmental health, human biomonitoring is now an important tool that is used to assess the internal exposure levels of individuals—and general populations—to environmental pollutants [ 23 , 24 , 25 ].…”

Metal pollution may lead to a variety of diseases; for this reason, it has become a matter of public concern worldwide. However, it is necessary to use biomonitoring approaches to assess the risks posed to human health by metals. In this study, the concentrations of 14 metal elements in 181 urine samples obtained from the general population of Gansu Province, China, were analyzed using inductively coupled plasma mass spectrometry. Eleven out of fourteen target elements had detection frequencies above 85%, namely, Cr, Ni, As, Se, Cd, Al, Fe, Cu and Rb. The concentrations of most metal elements in the urine of our subjects corresponded to the medium levels of subjects in other regional studies. Gender exerted a significant influence (p < 0.05) on the concentrations of Tl, Rb and Zn. The concentrations of Ni, As, Pb, Sr, Tl, Zn, Cu and Se showed significant differences among different age groups and the age-related concentration trends varied among these elements. There were significant differences in the urine concentrations of Zn and Sr between those subjects in the group who were frequently exposed to soil (exposed soil >20 min/day) and those in the group who were not, indicating that people in regular contact with soil may be more exposed to metals. This study provides useful information for evaluating the levels of metal exposure among general populations.

The study hypothesis is determined by the statement that the identification of a set of issues covering all stages of introducing technogenic deposits into economic turnover will allow focusing on solving a set of complex problems associated with technogenic mineral accumulations (mining waste). The aim of the study was to identify problems requiring priority resolution, which, in turn, accelerated the transition to a circular economy (implementation of the concept of closed supply chains) in the context of handling technogenic mineral accumulations. In the course of the study, issues of legal nature were identified (caused by the absence of the legal status of technogenic deposits and the regulation of their use regime in the Federal Law of the Russian Federation “On Subsoil”). A number of aspects are due to the complexity and cost of development of technogenic deposits, which are rightfully classified as unconventional types of raw materials, and in most cases require state support (for involving in commercial exploitation) in the form of a system of economic incentives, the feasibility of which should be confirmed by newly-elaborated regulatory legal acts. State should use the tools of public-private partnership in solving waste problems, in particular, referring to the positively proven experience of implementing regional target programs for processing of technogenic mineral accumulations. Viability of transition to circular economy in the sphere of handling technogenic mineral accumulations depends on the timeliness of the identified problems solution.
