[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.

[Ambient air pollution with flour dust at the sites of baking and macaroni enterprises].

Ambient air pollution with flour dust (FD) and microorganisms, including microscopic fungi, was studied; the single concentrations of FD under emission plumes were 0.12-0.17 mg/m3; the total content of mould, field, and storage fungi was 700 +/- 30, 671 +/- 19, and 29 +/- 3, respectively.

[Evaluation of cost-efficiency of improved life quality: methodological problems].

The paper deals with theoretical approaches to and practical methods of economic interpretation and measurement of negative changes in human health, quality of life. There is evidence that it is necessary to evaluate the health status as guidelines for estimating the cost effectiveness of hygienic recommendations. The authors propose guidelines for determining the contribution of individual pollution sources.

[Comparative assessment of enteral and inhaled n-butanol in laboratory animals].

Enteral and inhaled n-butanol given to albino rats was tested for toxicity in 2 series of subacute 30-day toxicological experiments. Enteral and inhalant administration caused membrano-, hepato-, adrenotoxic effects, and inhalant administration produced neurotoxic ones. The threshold dose was 0.
