The successful conduct of disinfection measures largely depends on the availability of veterinary practice a highly efficient, environmentally safe disinfectants. In this regard, finding new highly efficient disinfectant remains relevant. Studies found that the "Polied" (OOO "Razvitie XXI Vek, Russia) can be attributed to the highly efficient and environmentally friendly means. Solutions "Polied" have a high disinfectant activity against smooth and rough surfaces in the laboratory against gram-positive, gram-negative bacteria, mycobacteria and spores of microorganisms. Studies have established that solutions should be "Polied" obezzarajivatmi E. coli (EA 1257) concentrations of 0.1% on smooth surfaces and Staphylococcus aureus concentration of 0.05% in 1 hour from the calculation of 0.25-0.3 litres/m2. Disinfection of rough test surfaces against Escherichia coli and Staphylococcus aureus occurred after treatment with 0,3% solution of 3-hour exposure, at a rate of 0.5 l/m2. It was also found that 1.0% solution "Polied" fully obezzarazhivatel test the surface of mycobacteria (PCs-5) and at double the 0.6% concentration for 24 hours. Disinfection of rough test surfaces contaminated with spores of B. cereus (PCs 96) was achieved with a 4.0% solution at twice the irrigation rate of 0.5 l/m2 at an exposure of 24 hours. Toxicity solutions of the drug "Polied" refer to "moderate" threat (hazard class 3) and low-hazard substances (4 hazard class) when applied to the skin, mucous membranes of the eyes, and inhalation exposure on the respiratory system.

The article presents the results of a study of the "Bisolbi" drug toxicity (powder of light ash color, poorly soluble in water). When it is mixed with water it forms a suspension of particles that settle rapidly. Values of acute drug toxicity were determined on rats. We studied groups of six animals of the same sex, as well as similar control ones. The "Bisolbi" drug was injected to white rats intragastrically, males weighing 310 ... 320 g in doses of 2500 and 2740 mg / kg. Each dose was used in six animals; distilled water (3 ml) was used for the controls. The LD50 was calculated by the probit analysis method proposed by Litchfield and Wilcoxon modified by Z. Roth. When administered orally, an atraumatic metal probe was immersed in the stomach. Within 14 days monitored the overall health status and behavior of animals, the manifestation or absence of symptoms of intoxication; noted the features of feed and water ingestion, assessed the condition of the coat, physiological functions. Then groups of experimental rats were euthanized and pathomorphologically examined. We studied the effect of "Bisolbi" with repeated introduction and on not purebred dogs. Two groups of 3-4 years of age were completed with an average initial body weight of 13.63 ... 15.11 kg. Before use, the additive was thoroughly mixed with feed. The drug was injected during 31 days at a dose of 0.5 g / kg. Dogs of the control group (three) were fed wheat flour. After 15 and 31 days in laboratory animals in order to characterize the general condition in the blood, the amount of protein, urea, glucose, creatinine, cholesterol were determined. Based on studies it was found that the drug daily application by animals, is low toxic and safe, does not provoke the development of pathological reactions. According to the Hodge and Sterner classification "Bisolbi" can be attributed to the 6th class of toxicity - relatively harmless. Accordingto GOST 12.1.007-76 LD50 of the drug is more than 151 mg / kg, but less than 5000 mg / kg it is the 3rd hazard class (moderately hazardous).

Currently, perfluorooctanoic acid (PFOA) has no hygienic standards in the air of the working area and objects of the human environment in the Russian Federation. By the decision of the Stockholm Convention SC-9/12, PFOA, its salts and derivatives are included in Part I of Annex A of the Stockholm Convention on Persistent Organic Pollutants in 2019 (with exceptions for possible use). The Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade included PFOA, its salts and derivatives in the list of potential candidates for inclusion in Annex III of the Rotterdam Convention at the next meeting COP10 in 2021. The use of this chemical on the territory of the Russian Federation entails water and air pollution. Industrial emissions and waste water from fluoropolymer production, thermal use of materials and products containing polytetrafluoroethylene, biological and atmospheric degradation of fluorotelomer alcohols, waste water from treatment facilities are the sources of the release of PFOA into the environment. Analysis of international databases has showed that PFOA is standardized in the air of the working area in Germany, Japan, and Switzerland. In the countries of the European Union, as well as the USA and Canada, the issue of PFOA standardizing in drinking water is being now actively under discuss. Taking into account the high toxicity and hazard of the substance and the serious concern of the civil society of the Russian Federation, the Federal Service for Supervision of Consumer Rights Protection and Human Wellbeing requested the Russian Register of Potentially Hazardous Chemical and Biological Substances to develop MACs for perfluorooctanoic acid in the air of the working area and water as soon as possible. The MACs for PFOA have been proposed using risk analysis: 0,005 mg/m3, aerosol, hazard class 1 – in the air of the working area and 0,0002 mg/L, the limiting hazard indicator – sanitary-toxicological, hazard class 1 – in the water.
