Urinary mercury level in Japanese school children : influence of dental amalgam fillings and fish eating habits.
The influence of dental amalgam fillings and fish eating frequency on the urinary mercury (Hg) level was evaluated in 1642 children (ages: 3-18) living in Tokyo.
Geometric mean of the urinary Hg level was 1.9 mug Hg/l and 1.9 mug Hg/g creatinine (Cr) for boys and 2.1 mug Hg/l and 2.0 mug Hg/g Cr for girls.
Multiple regression analysis was conducted using:
(1) urinary Cr concentration (only in the case of urinary Hg expressed as mug Hg/l);
(4) number of dental amalgam fillings;
and (5) fish eating frequency as independent variables.
As a result, all the variables examined were significant and the explanatory powers (square of multiple correlation coefficient) of these variables were 17 or 7% for urinary Hg expressed as mug Hg/l or mug Hg/g Cr, respectively.
