[Rationale for the permissible level of carbon dioxide in indoor air in residential and public buildings with the permanent human presence].

On the base of the analysis of domestic and foreign data on the issue of rating of carbon dioxide in the indoor air of residential and public buildings and results of own research there is justified an permissible level of carbon dioxide in the indoor air of residential and public buildings with a permanent human presence. The concentration of carbon dioxide in the air space, not higher 1000 ppm (0.1%) was established to have no negative impact on the human health and performance, with this content of carbon dioxide there is no accumulation of toxic chemicals and registered by devices reducing of the oxygen content in the air of spaces, it meets the regulatory requirements for content dioxide carbon in the indoor air, applicable in most of foreign countries.

[On the question of occurrence and the problem of hygiene rating of fungal air pollution of the environment of residential and public buildings].

Comprehensive sanitary examinations of fungal pollution of the environment of residential and public buildings were performed. There is established the occurrence of sensitization of the population associated with the fungal contamination of the wallings of buildings and presence of viable mold spores in the indoor air environment. Major factors determining the degree of fungal contamination of indoor environments: increasing humidity of indoor air due to leaks and bays, the area of enclosure structures and the temperature factor have been identified.

[Fungal contamination of dwelling and public buildings: hygienic aspects].

Dwelling and public buildings underwent comprehensive hygienic studies for fungal contamination. Human allergization associated with fungal contamination within the building envelopes and with the viable fungal spores in the air of enclosed spaces was found to be prevalent. The leading factors determining the extent to which the internal environment of premises was exposed to fungal contamination: their increased air humidity due to leakages and inlets, the affected area of building envelopes, and a temperature factor were revealed. The criteria showing it necessary to undertake specific measures to optimize the living conditions of the population were defined.

[The effects of fungous semination of dwelling environment on the cytological status of human mucosal membranes].

High level of fungous semination of dwelling environment is shown to have a destructive effect on mucosal membranes, which is manifested by their inflammation and allergic condition. The study of the cytological status of the nasal and oral mucosa proved its high sensitivity and significance when studying the influence of fungous semination of dwelling environment on the human organism.

[Hygienic evaluation of genotoxic effects during artificial air ionization].

The study examined the potential genotoxic activity and the impact of artificial air ionization on lifespan. Experiments on Drosophila melanogaster demonstrated that exposure of the lung to negative (5 x 10(4), 5 x 10(5), and 10(6) ion/cm3) and slight positive (5 x 10(4), 5 x 10(5), and 10(6) ion/cm3) airoions generated on the electrodes at direct-current voltage failed to increase the frequency of dominant lethal mutations in the gametes and to affect the life-span of male flies. Exposure of the flies to deionized air increased the rate of early embryonic lethal mutations.

[Hygienic aspects of human sensitization under the influence of biological factors of the dwelling environment].

The paper deals with the risk of occurrence and development of allergic diseases under the influence of biological housing factors, such as molds, staphylococci, ticks, and insects. It shows that biological domestic allergens are of high importance in human sensitization. There is evidence that supports the allergic hazard of the above factors to children and adults.

[The human residential ecology: problems and future prospects]. / Ekologiia zhiloi sredy: problemy i perspektivy.

The article deals with the scientific as well as ecological-and-hygienic foundations of shaping the dwelling environment; it focuses on the real, total loads of the chemical, physical and biological factors experienced by the man under the conditions of the urban residential environment in Moscow. The risk factors, which are present in the residential environment, are investigated alongside with positive factors. A concept of the social-and-hygienic monitoring, which is to be a scientific basis for working out a comprehensive program of the optimization of the population habitation conditions and of ensuring the healthy life mode, is offered. This makes it possible to promote the preventive and current sanitary supervision over the structure and maintenance of living quarters and to ensure a new qualitative level for such supervision involving a quantitative assessment of the whole range of both positive and negative factors of the habitant environment; it is important for determining the housing quality and its safety for the population health.
