Abstract

The environment is polluted by chemical elements including heavy metals. Heavy metals accumulate in the human's body and adversely affect the organism, especially child's body. The purpose of this study was to assess the impact of excessive amount of elements on the child's body. Method: The levels of lead (Pb), cadmium (Cd) and strontium (Sr) were determined in urine and hair of 50 children (5-7 years old) by atomic absorption spectrometry in order to study the content of heavy metals in the body. Results: It was found that more than 60 % of the children had higher levels of Cd and Pb in the urine. Cd and Pb median in children's urine in the group with higher content of heavy metals were 0.15 and 1.28 p/l respectively and in the group within normal range of heavy metals - 0.07 and 0.34 p/l, respectively. In order to assess the impact of excessive amounts of heavy metals on the body the analysis of morbidity was done. Consequently, significant correlation has been established between the level of heavy metals in children's organism and incidence of upper respiratory tract infections, gastrointestinal tract disorders, anemia and changes in urine. Conclusion: Environmental pollution is a strong factor affecting human health and disease development. The impact of the environment on the children's body in large industrial cities is of particular interest for the development of preventive services and health care.
