Sanitary-hygienic study

Sanitary-hygienic study — A set of techniques that are used in hygiene in order to study the composition of air, water, food, soil, and other objects environment. With these studies also examine the impact of environmental factors on the human body. Sanitary-hygienic studies allow the development of preventive measures aimed at protecting the health and living conditions of the population, and to establish hygienic standards.
The simplest method of hygienic sanitary research is descriptive. However, he does not give a complete picture of the object being studied. Chemical, radiochemical and radiometric methods make it possible to identify any harmful to humans in various environmental objects. To establish such important health parameters, such as temperature, humidity, motion, and pressure of the air, noise, vibration, ultraviolet radiation, the integrated flux of radiant energy, air ionization, thermal conductivity of different materials, surface illumination, calorie food products, etc., are widely used physical Methods.
In assessing the food and drinking water are important organoleptic methods (see Wine).
Great importance in sanitary bacteriological research has study (Cm) of drinking water and food, as well as soil, household items, clothing and equipment in alimentary industry. Bacteriological studies are widely used in the staff survey companies alimentary industry and public catering network carrier of pathogenic bacteria. Samples for bacteriological analysis shall be taken in compliance with the rules regarding sterility (see Sanitary sample).
Helminthological methods (see) used in the sanitary-hygienic study of water, soil, vegetables, and meat in the control trichinellosis and measles. When the sanitary control of catering is important to check on personal health books, if not detected among workers suffering from worm infections, and if detected, conducted a treatment, care of an audit trail after treatment.
Of biological methods in the sanitary-hygienic study uses   method   bioassays to determine the toxicity of contaminants, the presence of toxins and other harmful substances.
Statistical methods are used in hygiene studies to study the influence of environmental factors on health.
To determine the influence of various factors environment the function and physiological responses of humans and animals are commonly used physiological and biochemical methods. These methods are also used to justify the maximum permissible concentrations of harmful substances in the air, water, water, air, plant facilities, food. In addition, biochemical methods are used when determining the biological value of foods and ready meals.
