1991년 5월 1일부터 약 6개월 동안 남자 1,193명 및 여자 658명을 대상으로 우리나라 도시 거주자들의 혈중 혈색소치, ZPP치 및 연농도를 성별, 연령별로 측정한 결과 아래와 같은 결과를 얻었다. 1. 혈색소의 평균치는 남자 $14.55{pm}1.82g/dl$, 여자 $12.61{pm}1.18g/dl$이었으며. 20세 이상군에서는 남자가 여자보다 유의하게 높았다(p<0.05). 2. 혈중 ZPP치는 $32.54{pm}9.88(32.09{sim}32.99{mu}g/dl,;95%;C.I.){mu}g/dl$ 이었으며 7세 미만 소아의 혈중 ZPP치는 남아 및 여아가 $37.49{pm}13.31{mu}g/dl$ 및 $35.77{pm}11.85{mu}g/dl$로 7세 이상군의 남자 및 여자의 $31.91{pm}8.23{mu}g/dl$ 및 $30.11{pm}9.11{mu}g/dl$보다 유의하게 높았다(p< 0.05). 3. 혈중 연농도는 $23.84{pm}4.58(23.55{sim}24.14{mu}g/dl,;95%;C.I.){mu}g/dl$ 이었으며, 7세 미만 소아의 혈중 연농도는 남아 및 여아가 $25.10{pm}5.21{mu}g/dl$ 및 $24.45{pm}4.18{mu}g/dl$로 7세 이상군의 남자 및 여자의 $24.28{pm}3.00{mu}g/dl$ 및 $21.99{pm}5.05{mu}g/dl$보다 유의하게 높았다(p<0.05). 이상의 결과를 요약하면 우리나라 도시 거주인은 남녀 모두 전연령에 걸쳐 높은 혈중 ZPP치 및 연농도를 나타내었으며 이러한 현상은 학동기전 소아에서 더욱 현저하므로 이들에 대한 관리대책 수립이 필요하다고 사료된다.
Hemoglobin (Hb), zinc protoporphyrin(ZPP) and blood lead (PbB) levels were determined for 1,851 blood samples collected from healthy urban population to establish reliable baselines for Hb, ZPP and PbB levels by age and sex. ZPP values were analyzed with a hematofluorometer and PbB determinations were concurrently carried out using flameless atomic absorption spectrophotometry. The blood sampling period was about 6 months from May, 1991 and the summarized results were as follows ; 1. The mean value of Hb in male and female were $14.55{pm}1.81g/dl$ and $12.61{pm}1.18g/dl$ respectively and there was statistically significant difference(p<0.05). 2. The mean value of ZPP in pre-schoolchildren was $37.49{pm}13.31{mu}g/dl$ for male, $35.77{pm}11.85{mu}g/dl$ for female and that of ZPP in after 7 years groups was $31.91{pm}8.23{mu}g/dl$ for male, $30.11{pm}9.11{mu}g/dl$ for female and there was statistically significant difference(p<0.05). 3. The mean value of PbB in pre-schoolchildren was $25.10{pm}5.21{mu}g/dl$ for male, $24.45{pm}4.18{mu}g/dl$ for female and that of PbB in after 7 years groups was $24.28{pm}3.00{mu}g/dl$ for male, $21.99{pm}5.05{mu}g/dl$ for female and there was statistically significant difference(p<0.05).
