Abstract

There are considered ecological-hygienic aspects of the sensitization rate of population in residential environmental. The considerable part of the life of a person passes in conditions of residential environmental, he is exposed to the whole complex of sensitizing factors, with the house dust being the most important among these factors. Results. According to results of our research, the greatest number of allergic reactions was noted under the contact with domestic, pollen and epidermal allergens. In the structure of allergic diseases in the population the most frequent were allergic rhinitis and allergic rhinoconjunctivitis. The overwhelming majority of observed cases was shown to suffer from functional disorders of the autonomic nervous system, gastrointestinal tract, and there was also observed the presence of chronic foci of inflammation. As a result of the executed comprehensive hygienic evaluation of the quality of residential environment there was established that in conditions of residential and public buildings the array of chemicals also had allergical effect on population. Discussion. The complex chemical pollutants of the residential environment in isolation was shown to fail to exert anaphylactogenic activity, whereas in complex with house dust allergen there are revealed the decline in immunological indices of the nonspecific resistance and inhibition of functional activity of T-suppressors, and amplification of immediate hypersensitivity in condition of impact of allergical complex of domestic dust. The existence of disorders of different functional systems of organism also provokes the development of the state of the hypersensitivity of population. Conclusions. The sensitization of the population was shown to be directly affected by the combined effect on human sensitization with allergenic components of house dust and chemical pollutants. Factors contributing to the development and occurrence of allergic pathologies among the population include: the level of chemical contamination of residential environment, various functional disorders of the body systems, which give rise in increased sensitization of the population.
