[Rationale for differentiated sanitary protection zones for battery recycling enterprises in modern conditions].

In the paper there is presented the rationale for differentiated sanitary protective zones in the present conditions both of the increase of volumes of production and introduction of various technological solutions on the example of battery recycling enterprise. It is established that the in acting regulations the classification of enterprises recycling of non-ferrous metals, fails to take into account such the hazard risks criteria of the enterprise, as volume of emissions of priority substances, the height of their arrival in the atmosphere, etc., and also does not take into account increased significantly in the current time processing volumes.

[The development of hygienic basis of odour regulation and control in ambient air and ways of harmonization in this field].

The work provides an overview of the major stages in the development of hygienic basis of regulation and control odour in our country and abroad. It indicates that the current methodology for the evaluation of odour due to its "obsessions" is consistent with the system of odour management in ambient air abroad based on the results of epidemiological studies. The methodology, based on the examination of the probability of perception not only the "indeterminate" smell, but smell with different intensity (odorimetriâ), aimed at preventing the appearance of "obsessive" smell among population, but without the time-consuming and expensive epidemiological studies has been proposed.

[Local immunity and methods for its assessment upon exposure to ambient air-polluting biologicals].

The investigators studied the impact of biological air contamination by the dusts resulting from protein feedstuff manufacture and grain on local immunity of the mucosae in children and adults living in the areas that were differently distant from industrial objects, the sources of contamination, as well as in workers of the shops contaminated by dust containing various amounts of protein. The studies showed that the workers of a biochemical plant exhibited a considerable change in the majority of immunological parameters (lysozyme activity, heterophile antibody titers, salivary and skin bactericidity, salivary total and R-protein, and immunoglobulins A, M, G, and E). There was a significant decrease in salivary IgA activity.

[Development of hygienic bases for air protection in the areas of industrial enterprises: results and prospects].

The paper presents the results of developments of the scientific principles in ambient air protection in Russia and outlines the prospects of their further development. The problems associated with ambient air hygiene can be solved when public and privately owned enterprises take an active part and financially support.

[Hygienic standards for ambient air pollutants: the-state-of-the-art and ways of harmonization].

The paper presents data on the harmonization of hygienic standards for ambient air pollutants and perspective lines for further development of these studies.
