CHANGES IN THE LEVEL OF MERCURY IN THE BLOOD OF WOMEN DURING PREGNANCY INCLUDING A RISK GROUP OF ITS CONTENT IN THE EARLY STAGES OF PREGNANCY

In our study we examined pregnant women in the early stages of pregnancy with the mercury content in blood over or equal to 0.73 mkg/l. The level of mercury in the blood of 129 examined women was equal to 0.95 mkg/l in the first trimester of pregnancy and 3.14 mkg/l in the third trimester (р ˂ 0.05). Thus, there was a noticeable increasing (3.3 times higher) of the mercury content during pregnancy in patients in these examined groups. In 25 cases the level of mercury in blood was equal to 3.77±0.66 mkg/l and the one in urine was equal to 1.65±0.46 mkg/l. We examined the mercury content in the cord blood of 16 infants of the studied women. It was found that the level of mercury in blood of pregnant women was equal to 3.42±0.85 mkg/l and 4.29±0.85 mkg/l in umbilical cord blood. Intramuscular injections of a 5% solution of unithiol in pregnant women of the risk group for mercury content in blood in the early stages of pregnancy improve perinatal indicators.
