  1. Urinary mercury level in Japanese school children : influence of dental amalgam fillings and fish eating habits.

    Article - En anglais

    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);

    • (2) age;

    • (3) gender;

    • (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.
