ABSTRACT. Neurological disorders are the leading cause of disability and the second leading cause of death worldwide. Was to determine the relationship between the prevalence of neurological diseases of the population of Dagestan and the content of manganese and lead in the soils and waters of the territory.
The content of manganese and lead in soils and waters of 6 administrative districts of the lowland zone of Dagestan was studied. The study was performed by the AAC method on a contrAA 700 c ETA spectrometer in an inert argon medium. The data of the Ministry of Health of Dagestan served as a source of indicators of the prevalence of neurological diseases among the population. In the study, a pattern was revealed: the higher the content of manganese, lead, the greater the neurological morbidity (general incidence of nervous diseases (GIND), peripheral neuropathy (PN), transient ischemic attack (TIA), cerebral ischemia (CI). GIND was positively correlated with the content of manganese in soils and waters (r = 0.52; 0.81), with lead (r = 0.53; 0.85). PN was positively correlated with the content of manganese (r = 0.52) and lead (r = 0.54) in soils. A strong positive relationship was observed with manganese and lead (r = 0.92; r = 0.93) in river and artesian water sources. TIA is associated with an average correlation with manganese (r = 0.71) and lead (r = 0.81) in soils. In water sources, manganese and lead had a value of r = 0.93. CI affected the population living in areas with relatively high lead content (r = 0.64) and manganese (r = 0.57) in soils. In water sources, the correlation coefficient was: for manganese (r = 0.77), lead (r = 0.81). Manganese and lead in the environment can affect the prevalence of disorders of the human nervous system, causing neurological diseases of the population.
