[PRIORITY TECHNOLOGIES OF THE MEDICAL WASTE DISPOSAL SYSTEM].

The annual production of waste in health care institutions (HCI) tends to increase because of the growth of health care provision for population. Among the many criteria for selecting the optimal treatment technologies HCI is important to provide epidemiological and chemical safety of the final products. Environmentally friendly method of thermal disinfection of medical waste may be sterilizators of medical wastes intended for hospitals, medical centers, laboratories and other health care facilities that have small and medium volume of processing of all types of waste Class B and C. The most optimal method of centralized disposal of medical waste is a thermal processing method of the collected material.

[Approaches of European and Russian legislation in the field of management of medical waste].

A comparative analysis of Russian and European legislation concerning to the waste management has been performed. There were revealed principal differences in Russian and European legislation in methodology of the waste classification. In Europe, there is no methodology for breaking up waste into hazard classes, and for the denomination of the danger there are used hazard lists which fail to give information about the extent of their danger. Medical waste in the European legislation are not selected into the separate category as being included in terms of articles and lists in the annexes to the directives or other legal acts. There are considered requirements of the Russian and European legislation in the area of the landfill waste burial. In the frameworks of the proposals for the implementation of international experience in the waste management there was drafted the project of Sanitary rules on hygiene requirements to the arrangement and the contents of landfills for residential solid waste, which includes requirements concerning not only residential solid waste, but also medical waste.

[The influence of the oil and gas industry on environmental safety and population health in the Khanty-Mansiiskii Region - Iugra].

Production activities of oil and gas industry plants are related to technogenic impact on the environment, which has a high environmental risk. This is associated with low levels of environmental orientation of sheer technological processes of exploration and exploitation of hydrocarbons and also used in this technical means, materials and chemical reagents. The main pollutants that deteriorate the toxic characteristics of drilling waste, are the most likely drilling fluids, mud flush agents and chemicals, which enter into their composition. Existing methods of disposal of drilling wastes are not effective, the technology of their use is often violated. Dumping drilling waste into water bodies and burying toxic waste in water protection areas under the guise of processed waste has been observed. In the region there are significantly exceeded the national average values rate of morbidity of allergic, cardiovascular, pulmonary and cancer diseases, mediated by environmental factors and new monofactorial and multifactorial diseases appear.

[Hygienic assessment of waste of soda production].

The object of investigations was soda industry waste. Slimes are formed at slimes storage which occupy considerable areas and are considered to be the source of permanent impact on the hydrosphere objects. Slimes storage placement within settlement boundaries and water protection zone of large watercourses leads to the deterioration of sanitary, hygienic and environmental situation and to the rising of risks to health of communities. Waste processing with getting new materials on the base of soda industry waste with wide application is seems to be one of the way for problem solving. It is essential to take into account sanitary and hygienic characteristics of slimes within justifying possible directions of its use. Thus, researches concerning assessment of physical, chemical and toxicological waste characteristics are considered to be actual. The aim of researches is to examine physical, chemical and toxicological characteristics of soda production slimes for justifying directions of its use including delivery of new materials respondent to the all regulatory sanitary and hygienic requirements. Experimental investigations of assessment physical, chemical and toxicological characteristics of slimes were carried out according to standard methods. Within assessment of toxicological slimes characteristics the following test-objects were used: Ceriodaphnia affinis, Paramecium caudatum. As a result of investigations watered slime samples were determined to be referred to the 4th hazard level (low-hazard) waste; samples with preliminary mechanical dehydration are referred to the 5th hazard level (practically nonhazardous) waste for environment. These are correspond to the 3rd and 4th hazard level according to sanitary regulations, respectively.

[Safety during the thermal disposal of medical waste containing PVC].

In the article the issues of environmental, sanitary and hygienic safety of medical waste management are considered. Recently, for the treatment of certain types of medical waste thermal methods using small plants not equipped with a proper flue gas cleaning system are widely used. In this article the potential danger of supertoxicants generation when applying thermal methods of neutralization of medical waste that contains polyvinyl chloride (PVC) is justified by thermogravimetric and mass spectrometric studies. This research shows the necessity of introducing technologies of separate collection of PVC medical waste and its' thermal recycling in compliance with special requirements.

[Researches of the structure of solid household waste and assessment of their sanitary and epidemiologic danger].

Compliance with hygiene requirements for the municipal solid waste (MSW) handling includes their composition control. The main methodological approaches to the MSW morphological composition study to assess their epidemiological risk are given. The main results of experimental waste composition analysis for a number of settlements are presented. These data were used for epidemiological risks estimation, measures for their minimization are suggested.

[Ultrasound in prevention of postoperative immunodeficiency].

Phonoprophylaxis of postoperative immunodeficiency was developed and tested in 34 patients. From the first day of hospitalization to the day of elective surgery the patients were daily exposed to ultrasound on the area of the manubrium sterni according to the labile technique through petrolatum or glycerol medium (0.05 W/cm2, 120-150 s, each other day, 4-6 procedures per course). Immune status studies after surgery prove a prophylactic effect of the above ultrasonic procedures.

[An experimental rationale for the use of sulfide sludge in adjuvant arthritis]. / Eksperimental'noe obosnovanie primeneniia ilovoi sul'fidnoi griazi pri ad''iuvantnom artrite.

The experiments on 176 Wistar rats were performed for the first time to clarify mechanisms underlying anti-inflammatory action of the Deshembinskoe Lake mud in experimental arthritis. The new data obtained gave evidence supporting application of Deshembinskoe Lake mud in inflammatory diseases of the joints.

[Experience in using sapropel mud in combination with a magnetic field in treating cervical osteochondrosis]. / Opyt primeneniia sapropelevoi griazi v sochetanii s magnitnym polem pri lechenii sheinogo osteokhondroza.

Patients with cervical osteochondrosis were successfully treated with Deshembinskoe Lake [correction of Deshembinskaya] sapropel mud in combination with exposure to magnetic field. The details of this treatment regimen are described. Combination of pelotherapy with effects of the magnetic field proved beneficial for patients with cervical osteochondrosis.
