Abstract
To acquire the essential basic data to the establishment of control measure for the hazardous health effect that could be caused by harmful metals, the author measured the concentrations of trace metals in whole blood of women of $20{\sim}39$ years old living in urban and rural area using atomic absorption spectrophotometer. The summarized results were as follows; 1. The mean concentration of zinc in whole blood was $10.69{\pm}8.07{\mu}g/ml$ in rural area. The frequency distribution by zinc concentration level was nearly L-type and the cumulative frequency distribution was showed bimodal type in both area. 2. The mean iron concentration in whole blood was $323.09{\pm}87.15{\mu}g/ml$ and $322.07{\pm}104.74{\mu}g/ml$ in urban and rural area, respectively. The frequency distribution was similar to normal distribution type in both area, but the cumulative distribution was unimodal type in urban area and bimodal type in rural area. 3. The mean magnesium concentration was $41.08{\pm}19.58{\mu}g/ml$ and $40.28{\pm}16.82{\mu}g/ml$ in the area, respectively. The frequency distribution type had skewness to the right and the cumulative frequency distribution was unimodal type in both area. 4. The mean copper concentration was $1.417{\pm}0.761{\mu}g/ml$ and $1.375{\pm}0.743{\mu}g/ml$ in the area, respectively. The frequency distribution type had skewness to the right and the cumulative frequency distribution was bimodal type in both area. 5. The mean manganese concentration was $0.079{\pm}0.039{\mu}g/ml$ and $0.07{\pm}0.058{\mu}g/ml$ in the area, respectively. The frequency distribution type had skewness to the right in both area but slight irregular in rural area and the cumulative distribution was unimodal and bimodal type in urban and rural area, respectively. 6. The mean cadmium concentration in whole blood was $0.031{\pm}0.026{\mu}g/ml$ in urban and $0.028{\pm}0.023{\mu}g/ml$ in rural area. The frequency distribution type had skewness to the right and cumulative frequency distribution was bimodal type in both area.
유해금속에 의하여 발생될 수 있는 건강장애를 예방하기 위한 대책수립에 필수적인 기초자료를 얻을 목적으로 도시 및 농촌지역에 거주하는 $20{\sim}39$세 사이의 가임연령여성 140명을 대상으로 하여 혈중미량금속원소들의 함량을 원자흡광광도분석기로 측정하여 얻은 결과를 요약하면 다음과 같다. 1. 혈중 아연의 농도는 도시지역 $10.69{\pm}8.07{\mu}g/ml$, 농촌지역 $9.53{\pm}6.60{\mu}g/ml$였으며 그 농도별 도수분포 양상은 양자 모두 L형에 유사하였고 이들의 누적분포 양상은 2봉성을 나타내었다. 2. 혈중 철의 농도는 도시지역 $323.09{\pm}87.15{\mu}g/ml$, 농촌지역 $322.07{\pm}104.74{\mu}g/ml$였으며 그 농도별 도수분포양상은 양자 모두 정규분포에 가까운 형이었으나 이들의 누적도수분포양상은 도시지역은 1봉성, 농촌지역은 2봉성을 나타내었다. 3. 혈중 마그네슘의 농도는 도시지역 $41.08{\pm}19.58{\mu}g/ml$, 농촌지역 $40.28{\pm}16.82{\mu}g/ml$였으며 그 농도별 도수분포양상은 양자 모두 오른쪽으로 치우쳐진 분포형으로서 이들의 누적도수분포양상은 1봉형을 나타내었다. 4. 혈중 동의 농도는 도시지역 $1.417{\pm}0.761{\mu}g/ml$, 농촌지역 $1.375{\pm}0.743{\mu}g/ml$였으며 그 농도별 도수분포양상은 양자 모두 오른쪽으로 치우쳐진 분포형으로서 이들의 누적도수분포양상은 2봉성을 나타내었다. 5. 혈중 망간의 농도는 도시지역 $0.079{\pm}0.039{\mu}g/ml$, 농촌지역 $0.07{\pm}0.058{\mu}g/ml$였으며 그 농도별 도수분포양상은 양자 모두 오른쪽으로 치우쳐진 분포형이었으나 농촌지역은 다소 불규칙한 양상이었고 이들의 누적도수분포양상은 도시지역은 1봉성, 농촌지역은 2봉성을 나타내었다. 6. 혈중 카드뮴의 농도는 도시지역 $0.031{\pm}0.026{\mu}g/ml$, 농촌지역$0.028{\pm}0.023{\mu}g/ml$였으며 그 농도별 도수분포양상은 양자 모두 오른쪽으로 치우쳐진 분포형으로서 이들의 누적도수분포양상은 2봉성을 나타내었다.
