Abstract: | We examined how the influence of smoking on blood and urinary cadmium (Cd) concentrations was modified by the level of environmental
Cd. We measured blood and urinary Cd concentrations of 1134 men over 50 yr of age in three areas in Japan that were exposed
to different levels of environmental Cd. Analysis of variance was used to compare Cd concentrations in blood and urine of
smokers with those of nonsmokers living in the three areas. Correlation coefficients between the number of cigarets smoked
per day or smoking indices (the number of cigarets smoked per day multiplied by the number of years smoked) and blood and
urinary Cd concentrations were calculated. No significant difference in Cd concentrations between smokers and nonsmokers was
observed in areas where the average Cd concentration in blood was over approx 2.4 ng/g, 2.0 μg/L in urine, and 2.3 μg/g creatinine
in urine, respectively. Therefore, it was suggested that an influence of smoking on blood and urinary Cd concentrations was
not observed in areas exposed to relatively high levels of environmental Cd. |
