The study covered the children living in Miasteczko Slaskie, near the largest Zn plant in Poland. This is one of the areas highly contaminated with heavy metals. The subjects were 158 children aged from 8 to 15 (98 boys and 60 girls). The average Pb and Cd levels in the hair of the entire children population was 8.21 +/- 5.59 microg/g, and 0.91 +/- 0.61 microg/g, and the average Pb and Cd levels in their blood were 14.32 +/- 3.98 and 0.52 +/- 0.24 microg/dL(-1), respectively. The children population under investigation was divided according to their sex. The hair of the girls contained, on the average, 5.06 +/- 2.81 microg/g of Pb and 0.74 +/- 0.48 microg/g of Cd and the hair of the boys 10.14 +/- 6.0 microg/g of Pb and 1.01 +/- 0.65 microg/g of Cd. The blood of the girls contained, on the average, 13.23 +/- 4.23 microg/dL of Pb and 0.48 +/- 0.21 microg/dL of Cd, and the blood of the boys 14.99 +/- 3.68 microg/dL of Pb and 0.55 +/- 0.24 microg/dL of Cd. Thus, both the hair and blood of the boys accumulated more Pb and Cd than those of the girls. A correlation between the concentrations of these metals was confirmed.
该研究涵盖了居住在波兰最大锌厂附近的米亚斯特茨科-斯拉斯基的儿童。这是重金属污染严重的地区之一。研究对象为158名8至15岁的儿童（98名男孩和60名女孩）。全体儿童头发中铅和镉的平均含量分别为8.21±5.59微克/克和0.91±0.61微克/克，血液中铅和镉的平均含量分别为14.32±3.98微克/分升和0.52±0.24微克/分升。被调查的儿童群体按性别划分。女孩头发中铅的平均含量为5.06±2.81微克/克，镉为0.74±0.48微克/克；男孩头发中铅为10.14±6.0微克/克，镉为1.01±0.65微克/克。女孩血液中铅的平均含量为13.23±4.23微克/分升，镉为0.48±0.21微克/分升；男孩血液中铅为14.99±3.68微克/分升，镉为0.55±0.24微克/分升。因此，男孩头发和血液中积累的铅和镉均多于女孩。这些金属浓度之间的相关性得到了证实。
