ABSTRACT. Objective – to
investigate specific patterns of trace element status of adult inhabitants of
Materials and Methods. A total of 178 occupationally unexposed adults aged from 20 to 80 years (99 men and 79 women) living in Yaroslavl were examined. In addition, examination of 113 adults (49 men and 64 women) living in a city with minor heavy industrial activities as a control group was performed. Assessment of hair trace element content was performed using inductively-coupled plasma mass spectrometry.
Results. When compared to the Russian reference values
the examined subjects were characterized by increased incidence of toxic metal
accumulation higher than 10% for cadmium, nickel, lead, tin, and especially
(> 20%). In turn, high incidence of low hair cobalt, copper, vanadium, and zinc content was observed. Further analysis demonstrated that hair aluminium, cadmium, nickel, and tin levels in Yaroslavl residents were 30%, 63%, 34%, and 28% higher as compared to the control location. Selenium and zinc content in subjects from Yaroslavl was 32% and 9% lower than the respective values in the control group, whereas hair V content was more than 2-fold lower. At the same time, adults living in Yaroslavl were characterized by 31% higher hair iron level.
Conclusions. Therefore, adults living in Yaroslavl city are characterized by increased accumulation of aluminium, cadmium, lead, tin and iron, in parallel with higher risk of zinc and vanadium deficiency. The revealed alterations of trace element status may at least partially contribute to development of environmental diseases of the population.
