Situational task N 28

At research of microclimate it is set in a operating hall of hospital, that time of cooling of katatermometer is| 600 sec., factor of katatermometer| - 60. Effective temperature – 16,5 ⁰ EТ|.

Give estimation|appraisal| to the microclimate. How to improve a microclimate in a room?

Situational task N 29

In the town C. for|after| the last 3 years it is exposed the growth|height| of morbidity of population by illnesses of liver|kidneys| and CNS|.

With the purpose of search of reasons|causes| of this phenomenon city|urban| SES| explored the levels of contamination of objects of environment. It is set that in water of storage pool, supplying a city|town|, content of organic substances makes 0,9 MPC|, salts of mercury – 0,8 MPC|. At the combined action on organism these substances give more, than additive effect (coefficient of potentiation -5).

Give the hygienic estimation|appraisal| of contamination of water. Is here intercommunication|relationship| of contamination of reservoir and growth|height| of this pathology among the population? What other factors of risk could stipulate multiplying these diseases? What hygienic measures|steps| is it necessary to conduct in the town?

Situational task N 30

In the town A. for|after| the last 3 years it is marked the growth|height| of morbidity of population by a sharp and chronic bronchitis |noted|, by bronchial asthma as compared to middle indexes on a region|area,domain|.

With the purpose of finding out of reasons|causes| of this phenomenon city SES|urban| |conducted researches of atmospheric air. In the atmosphere air of the city found out substance A|but|. at the level of 0,6 MPC|, substance B. in the concentration 0,5 MPC|. At the joint affecting on organism these substances possess less, than additive effect (antagonism|).

Give the hygienic estimation|appraisal| of degree of contamination of air in town. Is here intercommunication|relationship| of contamination of air and growth|height| of pathology at the population? What other factors can influence on growth|height| of morbidity of population? What are main sources of air contamination in the town and what|steps| is needed on the guard|guarding| of atmosphere from contamination?

Situational task N 31

In connection with an unfavorable|adverse| epidemiological situation in a district center A. (a few|a little| cases|accidents| of sharp intestinal infections are exposed) the analysis of water from a well is conducted.

Information|data| of analysis: a smell and taste of water - 1 ball|number|; the colour - 10 degrees; turbidity - 0,5 mg/l; coli-index| - 300; coli-titr| - 3.

Give a hygienic estimation|appraisal| to water. What index of water is it necessary additionally to explore? Could quality of water to provoke growth|height| of this pathology at the population? What antyepidemical measures|steps| are needed in this settlement?
