Comparative Indicators of Iron and Manganese Content in the Hair of Women Living in the Northern Region With Different Treatment of Drinking Water

Abstract

Aim: to study the concentration of Fe and Mn in the hair of women living in the cities of Khanty-Mansiysk Autonomous Region (KHMAO) with different treatment of drinking water. Methods. The ultimate composition of hair of 106 women (average age 38,9+11,3 g) - residents of the Northern region, not employed in the manufacturing sector was studied. 50 of them lived in the cities of Nefteyugansk and Nyagan and 56 - in the cities of Surgut and Khanty-Mansiysk. In the cities of Surgut and Khanty-Mansiysk underground water undergoes non chemical treatment, iron removal by the method of deep aeration and decontamination on UV irradiation installations. In the cities of Nefteyugansk and Nyagan water from artesian wells is decontaminated only by baclor. Results. The women living in the cities of Nefteyugansk and Nyagan had significantly higher (p < 0,001) and higher than reference values of Fe (82,3 + 11,4 mkg/g - the norm 7-40) and Mn (11,3 + 1,9 mkg/g - the norm 0,15-2,0) concentrations in the hair compared to women living in cities with high-quality purification of drinking water: Fe (23,6 + 2,2 mkg/g) и Mn (3,1 + 0,2 mkg/g). Iron, getting in to the organism with other pollutants (dietary Fe excess is not negative) also shows the properties of the immunosuppressant. Manganese is considered to be vital and at the same time a toxic element with mutagenic activity and tendency for accumulation. We can assume the best resistance to the adverse effects of oxidative stress in women-residents of KHMAO cities with optimal treatment of drinking water. Conclusions: To correct the microelement status of the Northern region population it is necessary to carry out more research of the environmental objects (in particular water) on the content of heavy metals, pay special attention to quality control of drinking water, and to use the method of microelement status determination of the hair chemical composition as an additional method of assessment of the internal body environment.

The effect of manganese ions (II) on representatives of aquatic biota

“…For algae, the average concentrations of manganese in biomass are 130-735 mg/kg, for shellfish -3-660 mg/kg, freshwater fish -0.2-19 mg/kg. Manganese in a living organism has mutagenic and cumulative properties [5].…”
