Exercise 15. Discuss the following facts and figures.
Ss. discuss the facts using the vocabulary and facts known from the text of
the Unit developing the ideas: what are the ways of problem solution,
what should be done to prevent the problems.
Exercise 16. Discuss the following problems. Find some additional
information to prove your point of view.
This task should be done with the help of Teacher on Geoecology.

UNIT 5
THE IMPACT OF CHEMICAL ELEMENTS
ON HUMAN ORGANISM
Lead-in. T. elicits information from the Ss related to the theme of the Unit.
Exercise 4. Read the following word-formations, translate into Russian.
Toxicology – toxicity – detoxify – toxic – toxicologically
To act – active – inactive – activity – activation
To produce – product – production
To absorb – absorption – absorptive
To transport – transportation – transportive
To metabolize – metabolite – metabolism
Exercise 5. Give Russian equivalents to the following words and set-
expressions.
To play an essential role – играть значительную роль
To result from – проистекать, вытекать из
To expand the scope – расширять границы
To provide the framework – обеспечить основу
Regardless of smth. – независимо от чего-либо
In response to – в ответ на что-либо

Exercise 8. Match the words with their definitions.
1. E, 2. D, 3. A, 4. C, 5. B.
Exercise 9. State whether each of the following sentences is true or false, if
false, explain why.
1. False - Momentum for its development as an independent discipline
has come from food safety, chemical warfare defence, product safety,
283
radiation biology, pesticide research, environmental medicine, and
immunology.
2. True.
3. True.
4. False – It is supposed that there are two mechanisms developed in
response to selection pressures indicating either of two biological
needs: to detoxify and excrete harmful substances ingested in foods
and to metabolize endogenous chemical compounds.
5. False – It indicates the entry of xenobiotic in the body.
6. False – The most common opportunities for exposure are skin contact
and breathing in the agent.
7. True.
8. True.
Exercise 10. Read the text again and make notes under the following
headings. Find some additional information on each of the topics. Talk
about the process of toxicokinetics.
This task is for the final lesson. The purpose of this task is to summarize
all the knowledge the Ss have got in the course of working at the Unit.
After each report T should stimulate the discussion on the considered
problems.
Exercise 11. Read the text and answer the questions.
1. What is biomagnification? – Biomagnification is the accumulation or
increase in the concentration of a substance in living tissue as it moves
through a food web (also known as bioaccumulation).
2. Give the examples of biomagnification of some elements. – The
examples are given in the text describing cadmium, mercury.
3. What are the main sources of contamination with heavy metals in
the environment? – They are by-products of the mining, refining, and
use of other elements.
4. Find some more information on the impact of some elements.
This task is for self-doing work. It may be checked either at the lesson or

disagreements which Ss have to learn in the course of General English and
after it. T. may write them on the board for visual support of the
dialogues.
Exercise 14.
a). Name the organs involved in each stage of toxicokinetics.
The exercise is a preparation stage for the next task.
Absorption may occur through lungs, mouth, skin, sometimes blood.
Distribution takes place through heart, capillary, blood.
Metabolism takes place in ventricle (stomach), liver, and pancreas.
Excretion occurs in kidneys, bowels (кишечник), lungs (expired air), gall
bladder (желчный пузырь).
b). Describe the processes of toxicokinetics using the picture.
