[Cytogenetic status of children in the hygienic assessment of the air pollution by odorous substances].

For the first time the impact of odorous emissions from the enterprise for the production of chewing gum on the cytogenetic status of children, residing in the distance of 0,9 and 6 km, was studied. Specific weak mint and fruity odour in the air in the placement of the enterprise may be related to the presence of menthol, menthone, pinene, limonene, ethyl acetate and other compounds containing in the emissions. There were no differences in cytogenetic status of children in both groups (by frequency of micronuclei, protrusions, binucleated cells, apoptosis).

[Immunological methods for assessing health in exposure to ambient air pollution].

In the article there have been analyzed the materials obtained in the study of human health state on the results of the study of immunological status. It was shown that the In mass hygienic studies the detection of the state of the human immune system has been shown to be the one of the most promising methods for the determination of human health state, as the immune system is the most vulnerable and feels the changes in the environment. At the same time it was pointed out that the non-invasive method for determining the human immunity is the most accessible.

[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 results of the performed research allowed to offer new positions in the classification of production of secondary lead from used batteries (I to IV class), depending on the volume of production (from 20 000 to 160 000 tons per year), the amount of emissions of lead (0.2 to 1, 6 tons per year) and release height (15 to 60 m).

[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.

[Relationship of structural-functional (histological and cytological) parameters with cytogenetic and cytotoxic ones in the evaluation of the influence of environmental factors on the organism].

The paper gives an assessment of the association of structural-functional (histological and cytological), cytogenetic, and cytotoxic changes in the analysis of various exposures of the body during both experiments (oral acrylamide) and population examinations (impact of pulp-and-paper mill waste on the nasal and oral mucosae). The assessment of the association of the study parameters is shown to serve to more completely objectify the pattern of actuating factors.

[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. The immunological parameters of children and adults were further compared with their morbidity as the most important health index. It was found that with the production rates being steadily raised, the average annual morbidity increment was 1.3; children less than 14 years of age in whom the incidence of bronchial asthma and bronchitis with asthmatic components increased 5-fold were most susceptible.

[Evaluation of physical exposures of motor transport during hygienic examination of design materials to establish the size of a sanitary break].

The paper presents the results of assessing the conformity of building, reconstruction, and highway maintenance with the standards, by establishing the size of a sanitary break during examination of design materials in case of the Saint Petersburg ring road, the West high-speed diameter, E-18 Scandinavia, surface high-speed line passenger railway routes in Saint Petersburg, etc.

[Non-invasive assessment used to evaluate the nasal and oral mucosal cytological status in sociohygienic monitoring].

By analyzing their own studies and the results of other studies by other investigators, the authors provide evidence that the noninvasive evaluation of the nasal and oral cytological status is one of techniques for assessing the health status and reflects the organism's state varying with environmental pollution, which enables it to be recommended for sociohygienic monitoring.

[The prospects of application of methods of population immune status evaluation when performing mass hygienic studies].

Non-invasive methods of sampling and a range of immunological assays for mass ecologo-hygienic studies of population were developed and introduced into practice in Sysin Scientific Research Institute of Human Ecology and Environmental Hygiene of Russian Academy of Medical Sciences. The studied materials were saliva, urine, breast milk, the condition of lymph nodes, and anamnesis. The complex of non-invasive methods was shown to be less complicated and, at the same time, informative and cheap, which allows recommending it for sociohygienic monitoring when performing mass hygienic studies.
