Abstract: The paper presents an overview of the main methodological approaches in experimental standardization of odorants (or mixtures of odorants) in the ambient air according to «obsessive» odor inadmissibility as a limiting criterion for justification of Maximum allowable concentration (MAC maximum one time dose) . It is shown that the developed procedure of establishing a permissible content of those substances is based on estimating the relationship «concentration – odor sensation probability of different intensit… Show more

With the growth of urbanization in large cities, the number of complaints from the population on unpleasant odors emitted by sewerage system facilities increases. In most cases, instrumental measurements on the content of individual malodorous substances in the zone of influence of sewerage facilities do not confirm the exceeding of the atmospheric air quality standards, even in terms of unpleasant odor. The lack of a clear system for standardizing odor in the atmospheric air and of established odor standards in Russia determined the relevance of this study. The aim of the study is to substantiate the permissible value of the odor emitted by sewerage system facilities. The article describes the research methodology. The results of field studies on the content of pollutants in the atmospheric air and the concentration of odor at the border of the sanitary protection zone of sewerage facilities are presented. The criteria for odor evaluation are proposed. The permissible value of odor for sewerage facilities is substantiated.

Environmental quality management requires the compliance with a number of conditions, such as the use of criteria for the reliable assessment of the health effects of harmful environmental factors (eg., hygienic standards, risk indices) and the optimization of factors of the laboratory control, including chemicals. The A.N. Sysin Research Institute of Human Ecology and Environmental Health (now part of the Federal State Budgetary Institution “Centre for Strategic Planning and Management of Biomedical Health Risks”) of the Ministry of Health of the Russian Federation has corrected domestic hygienic standards of chemicals in the water of water bodies in accordance with international recommendations, and standards of substances in ambient air - according to time characteristics and MPC values. Unified standards in water for substances belonging to the same structural class and not differing in the mechanism of action are justified, hygienic standards for a mixture of substances in atmospheric air have been established according to the criterion “obsession of the smell”. The developing methods of predicting the toxicity of substances make it possible to improve the planning of experiments in selecting doses and indices of the state of the organism. On more than 50 territories of the Russian Federation, a health risk assessment under the influence of chemical environmental factors was implemented. At the same time, an adequate assessment and control of environmental pollution are hindered by a number of circumstances, first of all, the lack of an optimal monitoring system and imperfection of its organization. Studies have shown the number of control indices from a few units to several tens, while hundreds of components that are not provided with regulations are identified. This is due to the lack of modern equipment and analytical methods. The solution to the problem lies in the systematic application of the methodology for selecting priority indices for monitoring. At the same time, an attempt to replace the assessment of the hazard of substances’ harmful effects on the body using generalized indices, for example, a unified “interagency index”, is untenable. The developed recommendations are aimed at improving the organization and methodology of environmental quality management.

The work of a number of enterprises is known to be accompanied with emissions into the air of complex multicomponent mixtures with a specific smell, the obsessive effect of which can cause complaints of the population, including various health problems. As a rule, abroad in these cases, only the level of psychological stress (“annoyance”) is evaluated without an objective analysis of the health status, which necessitates the development of a methodology for such analysis. Therefore, the work uses a wide range of health assessment of children: the cytological status of the cheek mucosa on 13 indices, the distribution of children according to three stages of adaptation and medical examinations of specialists to determine the health groups of children in control preschool institutions and preschool institutions located near the enterprise for the production of chewing gum. According to the research of cytological status using the non-invasive method, most of the indices did not differ significantly within the compared groups. The assessment of the health status according to the data of in-depth medical examination by specialists and the distribution by stages of adaptation allowed establishing certain differences in the studied indices in the children’s population, but these differences were assessed as preliminary. Earlier analytical studies have shown that many components forming specific odor emissions of the enterprise have an irritant effect on the mucous membranes of the eyes and upper respiratory tract. Meanwhile, all of them are in concentrations not exceeding their hygienic standards, which may cause the absence of the influence of a weak, barely noticeable odor (no more than 2 points) on the cytological status of children. The need to develop a comprehensive approach to the study of the mechanisms of the development of pathological conditions associated with odor, using multiparameter studies, including the analysis of psycho-emotional status, was shown.
