[INFLUENCE OF ENVIRONMENT FACTORS ON THE MORBIDITY RATE WITH TEMPORARY DISABILITY OF WORKING IN OIL REFINERY WORKERS].

There was performed a comprehensive assessment of working conditions of refinery workers on the results of the carrying out of certification of workplaces on working conditions. An analysis of the sample materials laboratory control over the content of harmful substances in the working area of industrial premises refinery. The prolonged exposure to harmful factors on the health ofworkers of the main production throughout the length of service was established to be a major riskfactor for the development of somatic and malignant diseases, to the gain in the morbidity rate and can become a cause of the emergency of malignancies.

[Factors of work environment and employment of workers in production of fuels and solvents at the oil refinery].

THEME: Factors of the industrial environment and labor activity of workers of manufacture propellants and solvents at the oil refining enterprise. OBJECT OF RESEARCH: Working conditions of workers at all installations of manufacture No 1 JSC "Naftan" of Novopolotsk of Byelorussia (production of fuels and solvents). THE AIM: Hygienic evaluation of working conditions of persons working in the production of fuels and solvents at the oil refinery. METHODS: Sanitary description of the production with hygienic analysis of project design and technological documentation, qualitative and quantitative characteristics of conventional methods in the work environment and working process of employees in the workplace for the main modes of operation of the equipment. THEORETICAL AND EXPERIMENTAL RESULTS: The working environment of refineries is influenced by a number of simultaneously acting factors, which have different material nature and characteristics of the action on the human body, the workers in production of fuels and solvents at the refinery, are exposed to a variety of hazardous and dangerous factors of production, a chemical factor is prevalent, of course.

[Assessment of risk for occupationally induced diseases in purification plant workers at a petroleum refinery].

The risk for occupationally induced diseases was assessed in purification plant workers at a petroleum refinery. The auxiliary process (purification and prepurification plants, biochemical purification) of the refinery OAO "Naftan" was the study object. Epidemiological, sanitary-and-hygienic studies were conducted to examine the negative influence of dangerous and harmful production factors on the workers' health status. The harmful and dangerous production factors recorded at this enterprise have been found to have a negative influence on the workers' health workers, which leads to the development of occupationally induced diseases in them.

[Preclinical health changes upon exposure to hydrocarbons of petroleum genesis].

A full-scale toxicological experiment established a complex of biochemical, clinical, and immunological parameters for the diagnosis of preconditions upon exposure to hydrocarbons, which was tested on children from two towns differing in the degree of ambient air pollution owing to hydrocarbons.

[Characteristics of demographic processes in the town of Novopolotsk]. / Kharakteristika demograficheskikh protsessov v gorode Novopolotske.

The study of demographic parameters in the town of Novopolotsk in 1970-1999 suggests that the most important causes of death among the town's population during this period are cardiovascular diseases (their proportion was 33.4-51.1%), malignant neoplasms (16.5-19.9%), and injuries (5.6-10.5%). In addition, there is an increase in mortality rates due to endocrine, respiratory, digestive, urogenital diseases, suicides, and injuries. In Novopolotsk residents, the main causes of death from cardiovascular diseases are atherosclerosis, coronary heart disease, and hypertensive disease.

[Hygienic aspects of the use of liquid wastes from oil-refining and chemical plants]. / Gigienicheskie aspekty utilizatsii zhidkikh otkhodov nefte- pererabatyvaiushchei i khimicheskoi promyshlennosti.

It is established that utilization of pond's acid tar and n-butyl-acrylate vat residue for the binding roadway covering composition and its further application are associated with the release of a significant amount of noxious substances into the air of the work zone and inhabited areas. A set of activities, directed at the reduction of negative influence of the given technology on the sanitary state of the workplace and community air has been developed.

[Medico-biological criteria of the evaluation of air quality at the site of microbiological synthesis plants]. / Mediko-biologicheskie kriterii otsenki atmosfernogo vozdukha v raione raspolozheniia predpriiatii mikrobiologicheskogo sinteza.

The efficacy of environmental protection in the areas of location of protein synthesis microbiologic plants was analyzed. It was established that under the conditions of observance of a technological regime and the stability of the gas cleaning systems for industrial affluents the operation of the plants caused no air pollution of residential districts by fungi producers and protein dust of the finished product. The study revealed the absence of detrimental health effect of microbiologic products. The proposed set of biomedical indicators can be recommended for monitoring air quality in the area of location of microbiologic plants.
