Special Issue Information

Dear Colleagues,

As is well known, exposure assessment generally includes information on the source and identity of chemical agents, the concentration of each toxicant in various media, and the toxicity of identified toxicants as defined in experimental studies. Thus, environmental exposure epidemiological methods examine the association between the effects of environmental agents on human health. Environmental epidemiology, on the other hand, is more often used to conduct hypothesis-based research that seeks to examine vulnerable populations or communities to clarify the relationship between adverse health effects and physical, biological, and chemical factors. Environmental exposures for the purposes of epidemiological research may broadly focus on exposure assessment for site remediation, mitigation, control, human health risk assessment, etc. Environmental exposures and epidemiological studies are needed to examine exposure to toxics and health effects and improve the availability of evidence for driving environmental policies to mitigation and prevention of environmental toxics in various media (air, water, food, and objects) presenting risks to human health. Thus, this Special Issue aims to share new information on monitoring, modeling, assigning exposure, and assessing associations with adverse health effects. Innovative articles responding to this issue should report original findings, reviews, and methods relevant to environmental exposures and epidemiology studies.

Most of the country’s oil and gas fields are situated in West Kazakhstan, mainly on the Caspian Sea coast, causing significant damage to the local environment and contributing to an imbalance in the trace element composition of the human body. The study is aimed to evaluate the relationship between the concentration of essential trace elements in scalp hair of the western Kazakhstan adult population and the remoteness of their residence from oil and gas fields. The concentration of essential trace elements (Co, Cu, Fe, I, Mn, Se, Zn) in the hair of 850 individuals aged 18–60 years was determined by inductively coupled plasma mass spectrometry. In residents of settlements located at a distance of >110 km from oil and gas fields, the concentration of Cu and I in hair was significantly higher than in those closer to 110 km (p < 0.001). The content of Cu and I were associated with the distance to oil and gas fields (0.072 (95% CI: 0.050; 0.094)) and (0.121 (95% CI: 0.058; 0.185)), respectively. We detected a significant imbalance in the distribution of some essential trace elements in residents’ scalp hair from the Caspian region of western Kazakhstan, living near oil and gas fields. The concentrations of Cu and I were significantly interrelated with the distance to oil and gas fields. The level of copper in the hair of both inhabitants of the area most remote from oil and gas facilities and the entire population of western Kazakhstan as a whole remains significantly low. The data obtained provide evidence of the possible impact of pollutants generated by the oil and gas facilities on a shortage of essential trace elements and associated subsequent health risks.
