- OBJECTIVES
To evaluate the blood and urinary cadmium concentration levels of around abandoned metal mines in comparison with a control group.
METHODS
Blood and urinary cadmium concentration levels were analyzed through investigations of the dietary habits and dietary water of subjects living near abandoned metal mines (exposure group) (n=190) in comparison with those living in designated control areas (control group) (n=256).
RESULTS
The blood cadmium (1.93 microgram/l) and urinary cadmium (2.41 microgram/g cr) concentrations of the exposure group were significantly higher than those of the control group (blood cadmium: 1.19 microgram/l, urinary cadmium: 1.94 microgram/g cr). Both concentrations were significantly higher in vegetarians in both groups.
CONCLUSIONS
The exposure group had higher blood and urinary cadmium concentrations than the control group. We attributed the elevated blood and urine cadmium levels in the abandoned mine residents to the influence of the abandoned mine sites.

- OBJECTIVES
To evaluate the level of maternal and prenatal mercury exposure and to analyze the related factors.
METHODS
Fifty-nine pregnant women were recruited into this study after obtaining informed consent. Samples were collected at delivery from normal pregnant women who were living in the city of Busan, Korea. Mercury concentrations in maternal and umbilical cord blood samples were measured using a gold-amalgam collection method. The total and methyl mercury levels of 36 of the 59 pregnant women were analyzed after randomization, and the results were compared.
RESULTS
The mean total mercury concentration was 3.16+/-1.21 ppb and 5.43+/-2.22 ppb in maternal and cord blood, respectively. The average, maternal blood mercury level was lower than the prescribed toxic limit for human (WHO, 5 ppb), whereas the cord blood mercury was higher. The mercury exposure level exceeded the WHO recommendation in 5 (8.47%) cases of maternal blood and 29 of (49.15%) cord blood. There was a significant correlation between maternal and cord blood mercury concentrations. Total mercury and methyl mercury concentrations of the 36 random pregnant women were 3.06+/-1.17 ppb, and 2.60+/-1.11 ppb in maternal blood, and 5.20+/-2.36 ppb, and 4.70+/-1.97 ppb in cord blood, respectively. Methyl mercury accounted for 85.0% of the total mercury in maternal blood and 90.4% in cord blood. There was a significant correlation between total and methyl mercury concentrations.
CONCLUSIONS
The study results suggest that mercury concentrations of cord blood may be regarded as indicative of high prenatal mercury exposure. Therefore, further studies are necessary to explain the cause of high mercury concentrations in cord blood, and to examine its relationship with various health indices.
