Topic 1.

Methodological and methodical basis of studying the influence of the complex

environmental factors on population’s health

1. The emissions of metallurgical enterprises penetrate into the athmospheric air of industrial center.They are : oxides of.sulphur, nitrogen, metals, carbon, affecting the population’s health . The effect of these dangerous factors is characterized as:

A * Combined

B Complex

C connecting

D adjacent

E Mixed

2. An increased general population’s morbidity has been noticed in the area of location of the industrial enterprise, where the atmospheric air is intensively polluted by sulphuric gas. What effect does the polluted air cause on the human organism?

A * Chronic nonspecific

B critical specific

C critical nonspecific

D Chronic specific

E Selective

3. An increased level of manganese has been noticed in the atmospheric air, drinking water and food of agricultural origin in the territory of the town. What is the effect of mentioned factors on the population’s health?

* A. Complex

B. Combined

C. linked

C. Synergic

D. Separate

4. The most active layer of living substance, which contains the bulk of organisms (including human population) and where the most active interaction between all the environmental components take place is called:

* A. Biostrome;

B. Biosphere;

C. Noosphere;

D. Neobiosphere;

E. Paleobiosphere

5. Insufficiently purified waste products of an industrial enterprise are dumped into the river, water from which is used for economic – drinking water-supply. This causes some micro-organisms’ death, disorder of self-purification processes of water and degradation of its quality that can have negative effect upon the state of human health. Such influence of environmental factors is called:

A * indirect

B Direct

C linked

D Complex

E Combined

6. In agriculture tillage is mainly realised by means of tractors, that are widely used in harvesting works on the whole. The main factors that have effect upon machine operators in the cabin of the tractor are unfavourable climate, vibration, noise, air polluted by dust, exhaled gases, pesticides, mineral fertilizers, etc. Besides we can observe physical overload, nervous and emotional overstrain. How do we call that kind of effect of the factors of industrial environment upon a person?

*A. linked

B. Complex

C. Isolated

D. Combined

E. Synergic

7. During the examination of the project of drainage of water it was noticed that the project provides discharge of insufficiently purified sewage of an industrial enterprise into the river, water from which is used for economic – drinking water-supply. It causes disorder of self-purification processes of water and worsening its quality that can have negative effect upon human health. That kind of influence of environmental factors is called:

A * indirect

B Direct

C linked

D Complex

E combined

8. Workers are under the influence of many harmful factors of industrial environment during the underground mining of ore deposits. They are: unfavourable microclimate, dustiness of air, high concentrations of toxic explosive gases, intensive noises and vibration. How is such influence of factors of industrial environment on a person called?

A.* linked

V. Combined

C. Isolated

D. Complex

E. Synergic

9. Complex of cyclic processes of metabolism and energy between separate components of the biosphere which are caused by vital activity of organisms is called:

* A. Circulation of components

B. Biogeochemical province;

C. Biogeocynosys

D. Ecological system;

E. Biogeochemical cycle;

10. High levels of noise and air polluted by sulphur anhydride are registered in a working area. What kind of harmful effect upon human organism can these factors cause under such conditions.

* A. Combined

B Separated

C. linked

D. Complex

E. Specific

11. Fused metal is poured in multiple forms for different casts in the foundry. Forms of metal or refractory materials are used. As a result of using such forms products of destruction and aerosols of condensation come into industrial environment ( beryllium, manganese, lead, chromium, carbon oxide, phenol, formaldehyde, ammonia and other chemicals are getting into the environment. How do we call such effect of factors of industrial environment on a person?

A. *Combined

V. Complex

C. Isolated

D. linked

E. Synergic

12. An increased level of manganese is registered in the atmospheric air, drinking water and food of plant origin in a residential area, located non far from an enterprise of ferrous metallurgy. What kind of effect of this factor does it cause upon population ‘s health?

A.* Complex
