16. Which major industries are responsible for water pollution?
OR
How are industries responsible for polluting freshwater? Suggest any three measures to reduce the water pollution. [CBSE (F) 2017]

Answer: Water pollution is caused by organic and inorganic industrial wastes and effluents discharged into rivers.

The main culprits are paper, pulp, chemical, textile and dyeing, petroleum refineries, tanneries and electroplating industries that let out dyes, detergents, acids, salts and heavy metals like lead and mercury, pesticides, fertilizers, synthetic chemicals with carbon, plastics and rubber, etc., into the water bodies.

Fly ash, phospo-gypsum and iron and steel slags are the major solid wastes in India.

Steps to minimize water pollution:

(i) Minimising use of water for processing by reusing and recycling it in two or more successive stages. Harvesting of rainwater to meet water requirements.

(ii) Treating hot water and effluents before releasing them in rivers and ponds. Treatment of industrial effluents can be done in three phases
(a) Primary treatment by mechanical means. This involves screening, grinding, flocculation and sedimentation.
(b) Secondary treatment by biological process
(c) Tertiary treatment by biological, chemical and physical processes. This involves recycling of wastewater.
(d) Overdrawing of groundwater needs to be regulated legally.

Many industries tend to come together to make use of the advantages offered by the urban centres known as ‘agglomeration economies. Gradually a large industrial agglomeration takes place. So, it is basically coordination of various industries’ in a city for the development of manufacturing industries.

20. Classify industries on the basis of capital investment.

Answer: Following is the classification of industries on the basis of capital investment:

(i) Small-scale Industries: A small-scale industry is defined with reference to the maximum investment allowed on the assets of a unit. This limit has changed over a period of time. At present, the maximum investment allowed is ₹1 crore.

Our traditional industries suffered a setback during the colonial period because they could not compete with the mill-made cloth from England.

23. How many cotton mills do we have in India?

Answer: Today, there are nearly 1,600 cotton and human made fibre textile mills in the country. About 80 per cent of these are in the private sector and the rest are in the public and cooperative sectors. Apart from these, there are several thousand small factories with four to ten looms.

24. What is the status of spinning and weaving in India?

Answer: While spinning continues to be centralised in Maharashtra, Gujarat and Tamil Nadu, weaving is highly decentralised to provide scope for incorporating traditional skills and designs of weaving in cotton, silk, jari, embroidery, etc. India has world-class production in spinning, but weaving supplies low quality of fabric as it cannot use much of the high quality yarn produced in the country. Weaving is done by handloom, power loom in mills.

25. To which countries are cotton goods exported?

Answer: India exports yarn to Japan. Other importers of cotton goods from India are USA, UK, Russia, France, East European countries, Nepal, Singapore, Sri Lanka and African countries. We have a large share in the world trade of cotton yarn accounting for one-fourth of the total trade.

26. How is jute industry associated with people?

27. Why is the iron and steel industry called a heavy industry?

Answer: Iron and steel industry is called a heavy industry because all the raw material as well as finished goods are heavy and bulky entailing heavy transportation costs. Iron ore, coking coal and limestone are required in the ratio of 4:2:1 approximately. Some quantity of manganese is also required to harden the steel.

28. Compare India’s steel production with that of China.

29. “Though India is an important iron and steel producing country in the world, yet we are not able to perform to our full potential.” Why? [CBSE (AI) 2017]

Answer: It is largely due to high costs and limited availability of coking coal. There is low productivity of labour. Moreover, there is irregularity of supply of energy and of course, the poor infrastructure.

30. What efforts should be made to improve steel production?

Answer: (i) Liberalisation and Foreign Direct Investment have given a boost to the industry with the efforts of private entrepreneurs.

For example, sulphuric acid is used to manufacture synthetic fibres and plastics or petrochemicals are used for producing synthetic fibres and synthetic rubber, etc.

33. Which ingredients are needed for the fertiliser production?

Answer: The fertiliser industry is centered around the production of nitrogenous fertilisers (mainly urea), phosphatic fertilisers, and ammonium phosphate and complex fertilisers, which have a combination of nitrogen, phosphate and potash. The potash is entirely imported as the country does not have any reserves of commercially usable potash or potassium compounds in any form. India is the third largest producer of nitrogenous fertilisers.

Answer: Major drawbacks:

• India has a large share in the world trade of cotton yarn but its trade in readymade garments is only 4 per cent of the world’s total.
• India’s spinning mills are competitive at the global level and capable of using all the fibres produced.
• But the weaving, knitting and processing units cannot use much of the high quality yarn that is produced in the country.
• There are some large and modern factories in these segments, but most of the productions are in fragmented small units, which cater to the local market.
• This mismatch is a major drawback for the industry. As a result, many Indian spinners export cotton yarn while garment manufacturers have to import fabric.
