Abstract
Total mercury content dynamics were evaluated in the hair of adolescent residents of the industrial center of North West Russia. The content of total mercury varied from less than 0.002 to 0.83mg/kg. The content of total mercury in the hair of males was 1.5-2 times lower than that of females. The relationship between the body mass index of females and the content of total mercury in the hair (for the entire observation period rs = 0.28-0.48, at p < 0.05) was observed. Metal's concentration in the hair of the study participants was found to depend on of fish consumption frequency. Total mercury concentration values were found to increase of 70% of the participants, by 0.03mg/kg per year on average, over 3years of study. Indicators of the content of total mercury in the hair of females and males in the city of Cherepovets did not exceed the standard values established in Russia and in the world. At the same time, the recorded values of the annual increase in the content of total mercury in the hair allow us to predict the potentially hazardous levels of metal in the body of the study participants when they reach adulthood.
