HYGIENE :

TSN "insight into the activities of

department" Ecology "

The purpose of the activity:•Ma

ster with the methodology of ecological zoning according to the degree of danger to human health

•Familiarize students with the criteria of hygienic assessment of the degree of contamination of environmental factors.

•Familiarize students with the evaluation criteria indicators of population health

•Teach to develop preventive measures for environmental protection

The student should know:The meaning and legal rules governing the

relationship of man to man, society and the environment.

Apply the basic provisions of each document in its significance

Features of the organization and conduct of sanitary and epidemiological measures

to mitigate the adverse effects of risk factors on health and the environment

The student

should be able to:

To carry on TSN controlled

municipal facilities.

Conduct sanitary inspection supervision and make the

appropriate accounting and reporting documentation.

Justify their actions to solve the problem;

TEST QUESTIONS

Which method is the study of public health in the evaluation of the pollution source

List the activities of sanitary protection of the environment

List the areas of environmental situation How many areas of observation must be

for ecological and hygienic assessment That such a favorable ecological

conditions

Lesson Content

Allocated 5 main gradations in levels of environmental pollution: a valid (number 1), moderate (number 2),

strong (number 3), very strong (number 4) and extremely strong (number 5). Accordingly, in these

territories severity of the observed pollution is estimated as allowable,

causing fear dangerous, very dangerous and extremely dangerous.

CONTINUED

Depending on the set of ecological and hygienic situation into 5 zones: the permissible situation tense situation, pre-critical situations, emergency and catastrophic situations (ecological disaster zone).The principle of hygienic assessment of the degree of air pollution based on the danger of pollution on public health; a comprehensive assessment of the aggregate of chemical and biological air pollution settlements, taking into account a number of physical parameters (temperature and municipal levels of noise).

To assess the extent of the total chemical air pollution is recommended to use the following indicators: a comprehensive integrated indicator of "P" or the air pollution index (API), which is estimated between 5 and 25 points, and the potential of air pollution - SHA (OT 3 to 15 points).Next figure - a potential risk of contamination of the atmosphere (SHA) is determined on the basis of the analysis of recurrence combinations of meteorological characteristics, causing dispersion, dilution and absorption of impurities (dirt) in the air basin: inversions, calm, fog, rain, wind speeds. Data on the value of SHA is available at all meteorological stations of the regions, in the Annual Bulletin Goskomgidromet.

CONTINUED

Most important is hygienic 10th indicator which indicates the degree of exceeding the

TLV for harmful substances in the water reservoirs. Of particular importance is the figure for the chemicals, normalized by the sanitary and toxicological limiting health hazard indicator. You can define it on the list of MAC of hazardous substances in water reservoirs sanitary and domestic

water use. Therefore, this figure is a high degree of relevance - 5 to 25 points.

Integrated hygienic assessment of areas in order to further their hygienic zoning

is impossible without the use of indicators characterizing the state of

health of the population; and the health of the population is considered as a

complex concept that includes conventional indicators such as the overall incidence of adult and child

population, diseases with temporary disability, disability, general and infant

mortality.

Assessment is based on the dynamics of indicators over the last 3 years. Demographic and other indicators analyzed in all localities rayoniruemoy territory and calculated per 1000 population. Coefficients "natural" movement are:

coefficient of total mortality, ie the ratio of the number of deaths for the year to the total population;

infant mortality rate, ie, the ratio of the annual number of deaths in children under 1 year old, to the number of births per year.

The criteria for evaluation of the indicators are approximate levels of these demographics.

TEST QUESTIONS Specify the range of health and demographic

indicators assessing the ecological status of the territories.

List gradation zone of ecological situation What groups of people conducted environmental

studies What is air pollution index How many zones are marked depending on the set of

ecological and hygienic situation What indicators are used to assess the extent of the

total chemical air pollution Materials of any LPU collects ecologist CSSES to

assess the incidence of urban What is the incidence How many districts must have for environmental and

hygienic evaluation.
