Total and inorganic mercury in breast milk and blood in relation to fish consumption and amalgan fillings in lactating women.
Total mercury concentrations (mean ± standard deviation) in breast milk, blood, and hair samples collected 6 wk after delivery from 30 women who lived in the north of Sweden were 0.6 ± 0.4 ng/g (3.0 ± 2.0 nmol/kg), 2.3 ± 1.0 ng/g (11.5 ± 5.0 nmol/kg), and 0.28 ± 0.16 pg/g (1.40 ± 0.80 mumol/kg), respectively.
In milk, an average of 51% of total mercury was in the form of inorganic mercury, whereas in blood an average of only 26% was present in the inorganic form.
Total and inorganic mercury levels in blood (r=55, p=003 ; and r=46, p=016 ; respectively) and milk (r=47, p=01 ; and r=45, p=018 ; respectively) were correlated with the number of amalgam fillings.
The concentrations of total mercury and organic mercury (calculated by subtraction of inorganic mercury from total mercury) in blood (r=59, p=0006 ; and r=56, p=001 ; respectively) and total mercury in hair (r=52, p=006) were correlated with the estimated recent exposure to methylmercury via intake of fish.
There was no significant between the milk levels of mercury in any chemical form and the estimated methylmercury intake.
A significant correlation was found between levels of total mercury in blood and in milk (r=66, p=0001), with milk levels being an average of 27% of the blood levels.
There was an association between inorganic mercury in blood and milk (r=96, p<. 0001) ; the average level of inorganic mercury in milk was 55% of the level of inorganic mercury in blood. (...)
