Mercury content and the ratio of stable nitrogen isotopes in the hair of residents from industrial city and specially protected natural area of Russia.

The mercury content in the hair of residents in the industrial city of Cherepovets (0.297 mg/kg) is three times lower than that of residents in the specially protected natural area of Kirillovsky district (0.877 mg/kg), which is approximately 110 km away from Cherepovets.

Dynamics of the total mercury content in the hair of adolescent residents of the industrial center of Northwest Russia (Cherepovets City).

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.

Hair Mercury Levels in Pregnant Women: Fish Consumption as a Determinant of Exposure.

The consumption of fish in food may contain mercury, a harmful element and dangerous chemical detrimental to human health. The purpose of this study was to determine the mercury level in the hair of pregnant women with different fish intakes in their diets. The concentration of total mercury in hair was determined using an atomic absorption spectrometer.

Effects of lipid extraction on stable isotope ratios of carbon and nitrogen in muscles of freshwater fish.

The extraction of lipids by the Folch method from the muscles of all the fish studied led to statistically significant differences in the values of N. At the same time, lipid extraction led to a statistically significant increase in C in pike and roach, and to a statistically insignificant decrease in C in perch and bream. Thus, lipid extraction cannot serve as a universal method of sample preparation for the analysis of the isotopic composition of carbon (C/C) and nitrogen (N/N) in fish muscles.

High variability of mercury content in the hair of Russia Northwest population: the role of the environment and social factors.

Purpose: The purpose of this work is to study mercury levels in the hair of different social and demographic groups of the population of the Vologda region in Northwest Russia. This region is selected due to a heterogeneous distribution of rivers and lakes-a resource base for fishing.

Methods: The mercury content was determined in the hair from the root with a length of about 2 cm.

Factors affecting the mercury concentration in the hair of young residents of the Vologda region, Russia.

The main aim of this study was to assess the level of mercury accumulation in the hair of students studying in the Vologda Region, Russia. Particular attention is devoted to clarifying the relationship between the metal concentration in the hair and the amount of fish in the diet. It was found that the mercury content in the hair of Vologda Region residents aged 17-21 is in the range from less than 0.

Long-term dynamics of total mercury in surficial bottom sediments of the Volga River's reservoir in central Russia.

The long-term dynamics of mercury in bottom sediments of Uglich Reservoir were examined. Samples of the 0-5-cm surface layer of bottom sediment collected during research expeditions in 1958, 1977, 1991, and 2012 were analyzed. An increase in the average mercury concentration from 1958 to 1977 (0.
