If compared to the WHO reference, levels of metals in whole blood demonstrated no excess in cobalt and cadmium, nearly absent - in arsenic, increased percentage of excess (but insignificant values) in copper and zincum, extremely high percentage of excess (and significant values) in manganese and nickel. Maximal manganese concentrations in blood reach 300 micrograms/l, those of nickel - 100 micrograms/l. Average blood concentrations of mercury in the examinees do not reach the most severe «level of concern for all ages» (5 micrograms/l), and shares of men and women with blood concentrations of mercury over this limit are relatively small. Average blood concentrations of lead in the examinees do not reach lower allowable level (50 micrograms/l).
