[Hygienic standardization of some biological pollutants in the water]. / Gigienicheskoe normirovanie riada biologicheskikh zagriaznitelei v vode vodoëmov.

Paper is devoted to problem of sanitary protection of water reservoirs from pollution by bioinsecticides and biosynthesis biologic waste. Experimental data on influence of biological pollutants on organoleptic water properties, water sanitary and toxicologic status are presented. Standards for open water bodies are recommended: dendrobacillin--6 x 10(4) org/l, trichodermin--2 x 10(4) org/l, grain moth pollen--0.05 mg/l, fodder yeast--0.08 mg/l, turingin--0.048 mg/l.

[Hygienic standardization of trichodermin in the air]. / Gigienicheskoe normirovanie trikhodermina v atmosfernom vozdukhe.

The article presents data on environmental pollution by trichodermin in the area of agricultural use of the chemical, as well as brief information on the toxicological assessment of the chemical with an indication of specific allergic effects. To prevent unfavourable effects of trichodermin on the population and to develop prophylactic measures it is necessary that hygienic standards be set for the chemical in ambient air. Therefore, the article presents results of the study of sensitizing properties of trichodermin obtained in experiments on animals under the conditions of long-term inhalational exposure to the chemical. 1 X 10(3) of microbic bodies per 1 m3 is recommended as trichodermin MAC according to the limiting allergic indicator.
