[Regional model of integrating occupational control over work condition into social hygienic monitoring system].

Existing practice implementing data obtained by occupational control and special evaluation of work conditions fails to evaluate hazardous effects caused in workers' health state by wide spectrum of risk factors such as social, ecologic, climate, etc. Widening possibilities for deeper health risk analysis can be provided by integration of laboratory and instrumental data on evaluation of hazardous and dangerous occupational factors into present systems of social hygienic monitoring. According to results of joint project within disciplinary program, Leningrad regional division of Federal Agency on sanitary epidemiologic supervision specified and implemented a regional model of integrated data base in informational funds of social hygienic monitoring. Consequently, quality and validity of management decisions in health risk factors control have significantly improved.i.

[Analysis of occupational morbidity and ways of further improving occupational therapy in Leningrad region].

Retrospective clinical and epidemiologic analysis covered occupational diseases in Leningrad region. Findings are that over recent years a tendency to lower number of primarily diagnosed occupational diseases continues. The authors justify necessity to work out the programs on prevention of occupational diseases in the region.

[Medicoecological studies in the assessment of biogeochemical province in the area of a toxic waste ground].

The paper presents the results of complex sanitary-and-epidemiological, toxicological-and-hygienic, and medical diagnostic studies of health and the environment, by taking into account the activity of a toxic industrial waste ground. Toxic waste burning on primitive unfiltered apparatuses was shown to lead to the formation of a biogeochemical province that is characterized by pollution of soil, bottom sediment, subsoil well water and snow with heavy metals, the components of toxic waste. Burning of waste and its storage in the open trenches resulted in ambient air pollution with organic solvents, nitric oxide and sulfur oxide had a negative impact on the health of children living at a distance of 3 km from the ground.

[Epidemiologic approaches to diagnosis of diseases dependent on ecologic factors]. / Epidemiologicheskie podkhody k diagnostike ékologozavisimykh boleznei.

The article deals with peculiarities in diagnosis of diseases caused by environmental hazards. The diagnosis covers population level and includes evaluation of environmental quality. Analysis of health for whole population and for risk groups enables to reveal "indicator" diseases. Social and hygienic monitoring, complex sanitary and ecologic examination recommend disclosure of facts and causes for any "nonspecific" diseases, definition of disorders caused by specific environmental hazards. The authors consider unity of hygienic and epidemiologic analysis for causative relationships in "human-environment" system in evaluation of noninfectious risk factors.

[Use of geographic information systems in the evaluation of medical and ecological situation in a city]. / Ispol'zovanie geograficheskikh informatsionnykh sistem dlia otsenki mediko-ékologicheskoi situatsii v gorode.

Study using geoinformational technology provides integrity and compatibility of diverse information about territories, determines "cause-effect" relationships between environmental pollution parameters and some health state parameters. Intensive technogenic pollution with cadmium, zinc, mercury, copper, chromium, lead, benzpyrene, radionuclides could be assessed through data of ecologic and social hygienic monitoring and results of research works.

[Method of determination of ecologically induced actual risk for human health and the degree of stress in medical and ecological situations]. / Metodika opredeleniia ékologicheski obuslovlennogo real'nogo riska zdorov'iu liudei i stepeni napriazhennosti mediko-ékologicheskoi situatsii.

Lipetsk town area was ranked according to maximal or minimal actual risk for public health (with consideration of medical and ecologic situation if influenced by technogenic hazards. That ranking enables to suggest municipal measures aimed at protection of population of ecologic hazards.
