[Prevalence of thyroid diseases in the Primorye Territory: ecological and hygienic aspects].

The paper presents the results of an ecological and hygienic assessment of the prevalence of thyroid diseases in the Primorye Territory. The analysis has indicated that the morbidity rates from different nosological entities depend on the bioclimatic zone, environmental and geochemical situation. Varying correlations were established between the soil concentrations of chemical elements (nickel, zinc, arsenic, silver, cobalt, and lead) and the degree of thyroid abnormalities in adults, adolescents, and children.

[Hygienic assessment of the impact of environmental factors of the Primorye Territory on the incidence of thyroid diseases].

The paper gives the ecological and hygienic characteristics of the Primorye Territory. It describes bioclimatic zones and ecological tension areas. The results of studies of the prevalence of thyroid diseases (diffuse endemic goiter, multinodular endemic goiter, subclinical hypothyroidism) associated with iodine deficiency in relation to the bioclimatic zone and the ecological situation are shown.
