우리나라 도시와 농촌 지역 주민의 혈중 연 및 혈중 Zinc Protoporphyrin농도 비교 연구 = The Level of Blood Lead and Zinc Protoporphyrin for Healthy Urban and Rural Population in Korea

다국어 초록 (Multilingual Abstract)

The study was carried out on healthy population in urban and rural area, in order to compare the level of blood lead (PbB) and blood zinc protoporphyrin (ZPP) between the population living in each area from July 1 1994 to December 31 1994. We stratificated the results with sex, age and area. The results obtained were as follows;
1. In urban area, overall mean of the PbB level was 7.08±1.61㎍/dl and both men and women had the highest level of PbB, which were 8.15±0.85㎍/dl, 6.90±1.48㎍/dl, in less than 39 years old group. In rural area, overall mean of the PbB level was 6.75±1.61㎍/dl and both men and women had the highest levels of PbB, which were 7.25±2.29㎍/dl, 7.00±2.92㎍/dl in 40∼49 years old group. And there was statistically significant difference between mean of the men's PbB level in urban area and that in rural area (p<0.05).
2. In urban area, overall mean of the ZPP level was 32.08±8.28㎍/dl and men had the highest level of ZPP, which was 29.59±5.13㎍/dl, in 40∼49 years old group, and women had that, which was 36.83±7.95㎍/dl, in less than 39 years old group. In rural area, overall mean of the ZPP level was 34.54±11.31㎍/dl and men had the highest level of ZPP, which was 32.10±5.45㎍/dl, in less than 39 years old group and women had that, which was 40.17±14.02㎍/dl, in 40∼49 years old group. And there was statistically significant difference between mean of the men's ZPP level in urban area and that in rural area (p<0.05).
3. There was statistically significant difference in PbB and ZPP between men and women group in both area (p<0.05) but not significant among age group in both area (p>0.05).
