PASSAGE - I

The problem of water pollution by pesticides can be understood only in context, as part of the whole to which it belongs – the pollution of the total environment of mankind. The pollution entering our waterways comes from many sources, radioactive wastes from factories, laboratories, and hospitals; fallout from nuclear explosions; domestic wastes from cities and towns, chemical wastes from factories. To these is added a new kind of fallout-the chemical sprays applied to crop lands and gardens, forests and fields. Many of the chemical agents in this alarming mélange initiate and augment the harmful effects of radiation, and within the groups of chemicals themselves there are sinister and little-understood interactions, transformations and summations of effect. Ever since the chemists began to manufacture substances that nature never invented, the problem of water purification has become complex and the danger to users of water has increased. As we have seen, the production of these synthetic chemical in large volume began in the 1940's. It has now reached such proportion that an appalling deluge of chemical pollution is daily poured into the nation's waterways. When inextricably mixed with domestic and other wastes discharged into the same water, these chemicals sometimes defy detection by the methods in ordinary use by purification plants. Most of them are so complex that they cannot be identified. In rivers, a really incredible variety of pollutants combine to produce deposits that sanitary engineers can only despairingly refer to as "gunk".

1. All the following words mean 'chemicals' except

3. The word 'gunk' in the last line refers

(a) to the waste produets deposited by sanitary engineers

(b) to the debris found in rivers

(c) to unidentifiable chemicals found in water

(d) to the domestie water supplies

4. Water pollution can only be understood

(n) in relation to world contaminntion

(b) by the whole human race

(c) in context

(d) in relation to the numberof pesticides that exist

5. Water contamination has become serious

(a) since water pollution was difficult to assess

(b) since nature has taken a hand in pollution

(e) since chemicals began to use new substances

(d) since businessman authorised the use of chemicals
