ABSTRACT. The work is devoted to the investigation of the effect of several trace elements (Zn, Co, Cu, Mn, Pb) in soil and drinking water of Dagestan (Kizilyurtovsky, Khasavyurtovsky, Babayurtovsky, Kizlyar, Tarumovsky and Nogay administrative districts of the republic), on human health (the prevalence of goiter endemia). Determination of elements content (Zn, Co, Cu, Mn, Pb) in soils and water was carried out by spectroscopic method on a spectrometer with the Zeeman effect AAS ETA Hitachi 170-70 with electrothermal atomization in argon of high purity, in a tubular graphite cuvette 170-5100.D. Indices of the prevalence of endemic goiter were identified by the indicators of the analytical center of the Dagestan Ministry of Health. The data on the prevalence of endemic goiter, the frequency of goiter and iodine deficiency, are analyzed in connection with the importance of these indicators of the endemic goiter in the population. It was established that soils of the plain zone are low-endowed with Co and Cu. At the level of the lower bound of the average supply was Zn, and for Mn and Pb the soils were at the level of high security. In our studies, it was found that for Mn the indices were 0.451.29 MPC, for Pb  0.50.67 MPC. The content of Zn, Co, Cu, Mn in natural waters is an order of magnitude lower than the MPC of these elements, while the Pb content was 0.561.68 MPC. The concentration of Zn, Co, Cu, Mn, Pb in the soils and natural water of the lowland zone of Dagestan with the prevalence of endemic goiter among the population was found to be related. At the same time, there was an increase in the parameters of pathology when the concentration of Mn, Pb was exceeded and Zn, Co, Cu were reduced in soils and natural water.

KEYWORDS: zinc, cobalt, copper, manganese, lead, soils, natural waters, public health.
