Thyroid hormone levels in men and women of southern Yakutia depending on the type of water consumed

In order to compare the level of thyroid hormones and antibodies depending on the use of filtered or untreated water, a survey of residents of the Aldan district of South Yakutia was conducted. As a result of the study, more pronounced changes in the level of thyroid hormones were revealed in women of Aldan. The frequency of violations of low levels of T3free, T3total, T4free is noted in people who use filtered water, which requires additional comparative study of the chemical composition of purified and untreated water consumed by the population.
