The study of the content of Pb, Cd, Ni, Zn, Mn, Cr, and Cu in biological media (the hair) of children living in the zones of the city of Kazan with different pollution levels was carried out. The identification of the zones in the city of Kazan was performed on the basis of the snow cover and soils pollution with heavy metals, which are natural accumulators of chemical substances and heavy metals (HM). Statistically significant differences (р < 0.01) in the content of certain metals in the hair, lead and cadmium in particular, were revealed in children living in the technologically polluted zone (Teplocontrol). Microelement composition of the hair in children with respiratory diseases (RD) varied widely in the content of lead (р < 0.05), and a statistically significantly lower level of zinc (р < 0.01) and copper (р < 0.05) compared with all the rest groups of children was determined in genitourinary diseases (GUD). However, relatively high values of toxic elements in the control zone show that the ecological status of the city and region is instable, and implies additional measures of the environmental monitoring and activities on chemical safety in certain city zones.
研究了生活在污染水平不同的喀山市区域的儿童的生物介质（头发）中 Pb、Cd、Ni、Zn、Mn、Cr 和 Cu 的含量。喀山市的区域识别是基于积雪和土壤中重金属的污染，这些重金属是化学物质和重金属（HM）的天然蓄积器。在技术污染区（Teplocontrol）生活的儿童的头发中某些金属（尤其是铅和镉）的含量存在统计学上的显著差异（р<0.01）。患有呼吸道疾病（RD）的儿童的头发微量元素组成中铅的含量差异很大（р<0.05），与所有其他儿童群体相比，锌（р<0.01）和铜（р<0.05）的含量明显较低。然而，控制区中相对较高的有毒元素值表明城市和地区的生态状况不稳定，需要在某些城市区域进行环境监测和化学安全活动的额外措施。
