Key concepts

Environmental pollution: types and sources

NCERT section Environmental Pollution (Table 9.1)

Pollution results from releasing substances and energy from human waste products; pollutants are the substances (and energy, such as noise) that cause it. Classified by medium:

Type	Pollutants	Sources
Air	Oxides of sulphur and nitrogen, carbon monoxide, hydrocarbons, ammonia, lead, aldehydes, asbestos, beryllium	Burning coal, petrol and diesel; industrial processes; solid waste and sewage disposal
Water	Odour, dissolved and suspended solids, ammonia and urea, nitrates, fluoride, oil and grease, pesticide residue, coliform bacteria, heavy metals (lead, arsenic, mercury), radioactive substances	Sewage, urban run-off, toxic industrial effluents, run-off from farms, nuclear plants
Land	Excreta, viruses and bacteria, garbage, pesticide and fertiliser residue, fluorides, radioactive substances	Improper human activities, untreated industrial waste, pesticides and fertilisers
Noise	Noise above tolerance level	Aircraft, automobiles, trains, industry, advertising media

Worked example

What is the difference between pollution and pollutants? (3 marks)

Try it first, then show the solutionSolution

1. Pollution is the result of releasing substances and energy from waste products of human activities into the environment, degrading air, water, land or causing noise.
2. Pollutants are the specific substances or forms of energy that cause it, e.g. oxides of sulphur and nitrogen, heavy metals, pesticide residues, or noise above tolerance.
3. Pollution is classified by the medium (air, water, land, noise) through which pollutants spread.

Answer: Pollution is the harmful condition; pollutants are the agents causing it.

Water pollution

NCERT section Water Pollution; Table 9.2; Namami Gange Programme

Causes: indiscriminate use by a growing population and industrial expansion degraded water quality. Surface water always contains some suspended particles and substances; when these increase, water becomes polluted and its self-purifying capacity fails.

• Natural sources (erosion, landslides, decay) exist, but human activities (industrial, agricultural, cultural) are the real concern; industry is the most significant contributor.
• Industries dump wastes, polluted water, poisonous gases, chemicals, heavy metals, dust and smoke into rivers and lakes, destroying their bio-systems. Major polluting industries: leather, pulp and paper, textiles, chemicals.
• Agricultural chemicals (fertilisers, pesticides, herbicides) wash into water bodies and infiltrate groundwater; fertilisers raise nitrate levels.
• Cultural activities (pilgrimage, religious fairs, tourism) also pollute. Almost all surface water sources in India are contaminated and unfit to drink.

Ganga and Yamuna (Table 9.2):

• Ganga: polluted downstream of Kanpur and Varanasi and at Farakka barrage; industrial pollution (Kanpur), domestic wastes of cities (Kanpur, Prayagraj, Varanasi, Patna, Kolkata), dumping of carcasses.
• Yamuna: polluted from Delhi to its confluence with the Chambal, and at Mathura and Agra; water extraction by Haryana and UP for irrigation, agricultural run-off with micro-pollutants, and Delhi's domestic and industrial waste.

Health: water-borne diseases like diarrhoea, intestinal worms, hepatitis; WHO data show about one-fourth of communicable diseases in India are water-borne.

Namami Gange Programme (with the National Mission for Clean Ganga): sewerage treatment in towns; monitoring industrial effluents; river front development; afforestation along banks for biodiversity; cleaning the river surface; 'Ganga Grams' in Uttarakhand, UP, Bihar, Jharkhand and West Bengal; public awareness to avoid pollutants, even through rituals.

Worked example

Describe the nature of water pollution in India. (5 marks)

Try it first, then show the solutionSolution

1. Growing population and industrial expansion have degraded water; when substances exceed the self-purifying capacity, water becomes unfit for use.
2. Industry is the most significant contributor: leather, pulp and paper, textile and chemical units release effluents and heavy metals into rivers and lakes.
3. Agricultural chemicals raise nitrate levels and reach groundwater; cultural activities like fairs and pilgrimages also pollute.
4. The Ganga (downstream of Kanpur, Varanasi, Farakka) and Yamuna (Delhi to Chambal confluence, Mathura, Agra) are badly polluted by industrial, domestic and agricultural wastes.
5. Water pollution causes diseases like diarrhoea, worms and hepatitis (about a quarter of communicable diseases); the Namami Gange Programme aims to clean the Ganga.

Answer: Mainly industrial, agricultural and domestic pollution of rivers and groundwater, causing disease; tackled by programmes like Namami Gange.

Air and noise pollution

NCERT section Air Pollution; Noise Pollution

Air pollution: addition of contaminants (dust, fumes, gas, fog, odour, smoke, vapour) in substantial proportion and duration harmful to plants, animals and property.

• Increasing use of fuels raises toxic gas emissions. Main sources: combustion of fossil fuels, mining and industries, releasing oxides of sulphur and nitrogen, hydrocarbons, carbon dioxide, carbon monoxide, lead and asbestos.
• Effects: diseases of the respiratory, nervous and circulatory systems; urban smog (smoky fog) harmful to health; acid rain: the pH of the first rain after summer is always lower than later rains in cities.

Noise pollution: an unbearable, uncomfortable state caused by noise; a serious concern recently due to technological innovations.

• Sources: factories, mechanised construction and demolition, automobiles and aircraft; periodic noise from sirens and loudspeakers at festivals and community events.
• Measured in decibels (dB).
• Traffic is the biggest nuisance; intensity depends on the type of aircraft, vehicle, train and road and vehicle condition. In sea traffic, noise is confined to harbours (loading and unloading). Industrial noise varies by industry.
• Location-specific: intensity declines with distance from the source (industrial areas, transport arteries, airports); hazardous in many metropolitan cities.

Worked example

What are the effects of air pollution on human health and the environment? (3 marks)

Try it first, then show the solutionSolution

1. Air pollution causes diseases of the respiratory, nervous and circulatory systems.
2. Smoky fog over cities (urban smog) is very harmful to human health.
3. It can also cause acid rain; in cities the first rain after summer has a lower pH than later rains.

Answer: Respiratory, nervous and circulatory diseases, smog and acid rain.

Urban waste disposal

NCERT section Urban Waste Disposal; Case Study: Daurala

Urban problems: overcrowding, congestion, inadequate facilities for fast-growing populations, poor sanitation and foul air. Solid waste has grown enormously: old and used articles like small metal pieces, broken glass, plastic containers, polythene bags, ash, CDs: called refuse, garbage and rubbish.

• Two sources: household/domestic (dumped on public lands or private contractors' sites) and industrial/commercial (collected and disposed through municipal facilities at low-lying landfill grounds).
• Ashes and debris from industries, thermal power houses and construction/demolition pose serious problems.
• Hazards: obnoxious smell; flies and rodents carry diseases like typhoid, diphtheria, diarrhoea, malaria and cholera; waste spread by wind and rain causes nuisance.
• Industrial waste dumped into rivers causes water pollution; city industries and untreated sewage cause health problems downstream.
• In metros like Mumbai, Kolkata, Chennai, Bengaluru, about 90 per cent of solid waste is collected and disposed; in most other towns 30-50 per cent is left uncollected, accumulating on streets and open spaces.
• Solution: treat waste as a resource for energy and compost; untreated waste ferments and releases toxic biogas including methane.

Case study: Daurala (near Meerut): based on 'polluter pays'; in 2003 villagers' plight drew attention: groundwater contaminated with heavy metals as untreated industrial wastewater leached into it. A Meerut NGO did a door-to-door health survey; NGO, villagers, representatives and industrialists worked together: overhead tank capacity raised and a 900 m pipeline for potable water; the silted pond desilted to recharge aquifers; rainwater harvesting structures to dilute contaminants; 1,000 trees planted. A model of ecological restoration with people's participation benefiting twelve thousand residents.

Worked example

Mention the major problems associated with urban waste disposal in India. (3 marks)

Try it first, then show the solutionSolution

1. Huge and growing quantities of solid waste; in most towns 30-50 per cent remains uncollected on streets and open spaces.
2. Waste causes foul smell and breeds flies and rodents that spread typhoid, diarrhoea, malaria and cholera; untreated waste releases toxic gases like methane.
3. Industrial waste and untreated sewage dumped into rivers cause water pollution and health problems downstream.

Answer: Uncollected waste, disease spread, toxic gases and river pollution.

Rural-urban migration

NCERT section Rural-Urban Migration; A Case Study

Causes: high demand for labour in urban areas, few job opportunities in rural areas and unbalanced development between urban and rural areas. City populations are rising fast; poor people often bypass small and medium cities and go straight to mega cities.

Global context (box): 55 per cent of the world lives in cities, expected to reach 68 per cent by 2050. Urban population grows by natural increase, net in-migration and reclassification of rural areas. In India, after 1961, about 60 per cent of urban growth is attributed to natural increase and about 29 per cent to rural-urban migration (as the textbook estimates).

Case study: Ramesh:

• Works as a contract welder at construction sites (Talcher coal region, Odisha; earlier Surat, Mumbai, Gandhinagar, Bharuch, Jamnagar); sends Rs 20,000 a year home.
• Remittances used for consumption, health care, children's schooling, agriculture, land and houses; the family's living standard improved.
• Fifteen years earlier: three brothers' families on three acres, heavy debt; Ramesh left school after Class 9; married; inspired by successful migrants in Ludhiana, he moved there and worked in a woollen factory for Rs 20 a day (1988), struggling with income and assimilation to a new culture; then moved to Surat, learnt welding.
• He bears the pain of separation: the job is temporary and transferable, so he cannot bring his family.

Comments: poor, semi-literate, unskilled rural migrants often end up in menial, low-wage, informal urban jobs; wives stay behind to care for children and elders, so the migration stream is male-dominated.

Worked example

Using Ramesh's case, explain the push and pull factors and consequences of rural-urban migration. (5 marks)

Try it first, then show the solutionSolution

1. Push factors: abject poverty, three families on three acres, heavy debt, and lack of rural jobs.
2. Pull factors: perceived job promises in Ludhiana and the example of successful migrants sending money home; urban demand for labour.
3. Economic consequences: remittances of Rs 20,000 a year improved consumption, health care, schooling, farming and housing in the village.
4. Social consequences: difficulty assimilating to a new culture, low wages at first, and separation from family because jobs are temporary and transferable.
5. General pattern: poor, unskilled migrants take low-wage informal jobs, and spouses stay behind, making migration male-dominated.

Answer: Poverty pushes and urban jobs pull; migration brings remittances but also hardship and family separation.

Problems of slums

NCERT section Problems of Slums; Dharavi

Rural and urban areas are different in function and have become separate cultural, social, political, economic and technological worlds. India was about 69 per cent rural (2011); Gandhi saw villages as ideal republics, yet most rural areas are poor and act as hinterlands of urban centres.

The divided city: urban centres are highly differentiated: at the top, farm houses and high-income localities with wide roads, streetlights, water and sanitation, lawns, green belts, parks and security; at the other extreme, slums, jhuggi-jhopri clusters and shanty colonies of people forced from rural areas who cannot afford proper housing due to high rent and land costs, occupying environmentally incompatible and degraded areas.

Slum conditions: residential areas of least choice: dilapidated houses, poor hygiene and ventilation, lack of drinking water, light and toilets; open defecation, unregulated drainage and overcrowded narrow streets create health and socio-environmental hazards.

• Most slum dwellers work in low-paid, high-risk, unorganised sectors; they are undernourished, prone to diseases, and cannot afford proper education for children.
• Poverty makes them vulnerable to drug abuse, alcoholism, crime, vandalism, escapism, apathy and social exclusion.
• Swachh Bharat Mission (SBM): part of the urban renewal mission to improve life in urban slums.

Dharavi, Mumbai (Asia's largest slum; Seabrook, 1996): buses only skirt it; one main road ('ninety-foot road', now much narrower); alleys too narrow for bicycles; two-three storey temporary buildings with whole families of twelve or more in one room; uncollected garbage and stagnant water; yet it produces fine ceramics, embroidery and zari work, leather goods, garments, metalwork, jewellery settings, wood carvings and furniture sold in rich homes in India and abroad. It was once an arm of the sea filled with waste; buildings for treating hides and tanning.

Worked example

Describe the problem of slums in India. (5 marks)

Try it first, then show the solutionSolution

1. Slums arise because rural migrants searching for livelihood cannot afford housing due to high rents and land costs, so they occupy degraded, environmentally incompatible areas.
2. Living conditions: dilapidated houses, poor hygiene and ventilation, no proper drinking water, light or toilets; open defecation and poor drainage cause health hazards.
3. Economic problems: most work in low-paid, high-risk, unorganised jobs, are undernourished and prone to disease, and cannot educate their children well.
4. Social problems: poverty leads to drug abuse, alcoholism, crime, apathy and social exclusion.
5. Example: Dharavi, Asia's largest slum, overcrowded and unsanitary yet producing valuable goods; schemes like Swachh Bharat Mission aim to improve slum life.

Answer: Slums suffer poor housing, sanitation, health and livelihoods and social exclusion, though they contribute to the city economy.

Land degradation and the Jhabua case study

NCERT section Land Degradation; A Case Study: Jhabua

Land degradation: a temporary or permanent decline in the productive capacity of land, caused by soil erosion, waterlogging, salinisation and alkalinisation, or continuous use without managing fertility. Degraded land is not always wasteland, but unchecked degradation can turn it into wasteland.

Processes (NRSC classification using remote sensing):

• Mainly natural: gullied/ravinous land, desertic or coastal sands, barren rocky areas, steep slopes, glacial areas.
• Natural and human: waterlogged and marshy areas, land affected by salinity and alkalinity, land with or without scrub.
• Mainly human-made: degraded shifting cultivation areas, degraded land under plantations, degraded forests and pastures, and mining and industrial wastelands.

Wastelands caused by human-made processes are more important than natural ones.

Case study: Jhabua (Madhya Pradesh):

• In MP's westernmost agro-climatic zone; one of India's five most backward districts; mostly Bhil tribal people; poverty worsened by degradation of forests and land.
• Watershed management programmes funded by the Ministries of Rural Development and Agriculture succeeded in preventing land degradation and improving soil. They link land, water and vegetation and improve livelihoods through natural resource management and community participation. In five years, the Rajiv Gandhi Mission for Watershed Management treated 20 per cent of the district's area.
• Petlawad block: a successful Government-NGO partnership. Bhils of Sat Rundi hamlet (Karravat village) revitalised common property resources: each household planted and maintained one tree, planted fodder grass, adopted social fencing for at least two years, and planned stall feeding instead of open grazing.
• Conflict resolution: an encroacher from a nearby village was made a member of the user group to share benefits rather than being excluded.

Worked example

Suggest measures for reducing land degradation, with reference to the Jhabua case. (5 marks)

Try it first, then show the solutionSolution

1. Identify degraded areas and their causes (NRSC remote sensing); human-made degradation (forests, pastures, mining) is more important, so human practices must change.
2. Adopt watershed management linking land, water and vegetation, with community participation, as in Jhabua (20 per cent area treated).
3. Regenerate common property resources: plant and maintain trees and fodder grass, as each household did in Petlawad.
4. Protect regenerating land through social fencing and stall feeding instead of open grazing.
5. Use Government-NGO partnerships and include all users (even encroachers) in user groups to share benefits and avoid conflict; also control waterlogging and salinity in irrigated areas.

Answer: Community-based watershed management, afforestation, pasture regeneration, controlled grazing and inclusive user groups.

5. Q5 · 3 marks · Short answerBoard level

   Why is industry considered the most significant contributor to water pollution? (3 marks)

   Hint

   Effluents.

   Answer

   Industries produce wastes, polluted water, poisonous gases, chemical residues, heavy metals, dust and smoke, and dispose of most wastes into running water or lakes. Poisonous elements reach reservoirs and rivers, destroying their bio-systems. Leather, pulp and paper, textile and chemical industries are major polluters, e.g. at Kanpur on the Ganga.

6. Q6 · 3 marks · Short answerHOTS / competency

   Suppose a city has gated colonies with parks and wide roads next to crowded jhuggi clusters without toilets or clean water. Using the chapter, explain why such a divided city develops and its consequences for slum dwellers. (3 marks)

   Hint

   Migrants, high rent.

   Answer

   Urban centres are highly differentiated: high-income localities have good infrastructure, while rural migrants who come for livelihood cannot afford housing because of high rents and land costs, so they live in slums on degraded land. Slum dwellers face poor hygiene, lack of water and toilets, disease, low-paid risky informal jobs, poor schooling for children and risks of drug abuse, crime and social exclusion.

7. Q7 · 3 marks · Short answerHarder board level

   Distinguish between natural and human-made processes of land degradation with examples. (3 marks)

   Hint

   NRSC classification.

   Answer

   Natural processes create gullied/ravinous land, desertic or coastal sands, barren rocky areas, steep slopes and glacial areas. Some lands are degraded by both natural and human factors: waterlogged and marshy areas, saline and alkaline land, land with or without scrub. Human action creates degraded shifting cultivation areas, degraded plantations, forests and pastures, and mining and industrial wastelands; these human-made wastelands are more important.

8. Q8 · 5 marks · Long answerHOTS / competency

   Describe the water pollution of the Ganga and Yamuna and the steps taken to clean the Ganga. (5 marks)

   Hint

   Table 9.2 and Namami Gange.

   Answer

   Ganga: polluted downstream of Kanpur and Varanasi and at Farakka barrage by industrial pollution from towns like Kanpur, domestic wastes from Kanpur, Prayagraj, Varanasi, Patna and Kolkata, and dumping of carcasses. Yamuna: polluted from Delhi to its confluence with the Chambal and at Mathura and Agra, due to water extraction for irrigation by Haryana and UP, agricultural run-off with micro-pollutants, and Delhi's domestic and industrial waste. To clean the Ganga, the National Mission for Clean Ganga and the Namami Gange Programme aim at sewerage treatment, monitoring industrial effluents, river front development, afforestation along banks, cleaning the river surface, Ganga Grams in five states, and public awareness against adding pollutants even through rituals.
