“…An assessment of gender differences in the content of Cu, Zn, Co, Fe, Cr, Mn, Cd, As, Pb, Ni, P, Ca, K, and Mg in the hair of residents from Central Kazakhstan determined that the level of these microelements in the hair of men is higher compared to women. This result is consistent with the data of Tamburo et al [ 9 ], Sal'nikova et al [ 20 ], and Mussabekova et al [ 5 ]. The levels of Cd and Pb in male and female hair do not always have statistically significant differences [ 21 , 22 ].…”

“…For many, the manufacturing sector is a potential source of exposure to Cu, Zn, Co, Fe, Mn, Ni, As, Cd, and Pb [ 30 ]. Professions such as miners, foundry workers, welders, mechanics etc, are at especially high risk of contact with Cd and Pb [ 20 , 27 ]. Buononato et al [ 26 ] and Cabral Pinto et al [ 31 ] note an increase in the average concentrations of Pb in the hair samples of men employed in the metallurgical industry.…”

“…There is evidence in the literature that the content of certain microelements (Zn, Cr, Cd, Mn, As, Ni, Cu, Pb) in hair increases with age [ 34 , 35 ]. However, according to the results of other scientists, there is no clear correlation between age and accumulation of, for example, Cd and Pb [ 20 ]. Our experiments helped to determine that the process of chemical elements deposition in human hair with aging depends on gender.…”

If an individual cannot be identified, it is necessary to conduct a forensic medical examination. In this case, all possible group indexes are investigated. In this study, the content of elements in hair was investigated to identify individuals by territory, age, profession, or gender. The level of 14 micro- and macroelements (Cu, Zn, Co, Fe, Cr, Mn, Cd, As, Pb, Ni, P, Ca, K and Mg) was determined in hair samples of men and women from five age categories (21 to >60) using inductively coupled plasma atomic emission spectroscopy. The samples were analyzed taking into account the health condition, gender, place of residence, occupation, work experience, and age. A correlation between the content of elements in people's hair and their place of residence was observed. The difference in the content of elements in the hair of urban and rural residents was substantial and statistically significant (p<0.05). Moreover, there were significant differences related to age (p<0.0051) and gender (p<0.05). The current research detected significant differences in the content of the chemical elements in the hair of the groups tested, which can be used as personal identification indicators depending on occupation, work experience, and environmental factors.

Today road transport has acquired a leading role in forming of environmental components` quality. The number of cars in the last years 3-5 years in many cities has doubled and somewhere even tripled. Orenburg region isn’t exception. If we consider the dynamics of the formation of the car park in Orenburg for the past few years, then it doubled, and there is a priority growth in the number of passenger cars. So, the trends in the quantity and quality of vehicles in Orenburg make it possible to predict an increase in the further adverse impact on the quality of the environment associated with the operation of vehicles. Cadmium enters the natural environment as a result of tire wear and abrasion of asphalt concrete. Nickel and chromium are wear products of body coatings, iron is a product of engine cylinder abrasion. Lead and cadmium are traditionally considered the most dangerous pollutants of the natural environment among heavy metals. It has been established that 75% of the lead contained in the fuel of an internal combustion engine is released into the air as part of aerosols in combination with chlorine and bromine ions and is scattered. The purpose of the study is to assess the ecological situation of the roadside territories of Orenburg streets. The most polluted objects in terms of the biogeochemical indicator are the crossroads of streets in the historical part of Orenburg, the roadside area of Sovetskaya Street is less polluted.
