The Air Act was enacted by the parliament in

  1. 1980

  2. 1981

  3. 1891

  4. 1781


Correct Option: B
Explanation:

The Air (Prevention and Control of Pollution) Act was enacted in 1981. This act emphasizes the prevention, control and abatement of air pollution in India. It states that sources of air pollution such as industries, vehicles, etc, are not permitted to release toxic chemicals beyond a prescribed level. Thus the correct answer is option B.

Steps taken by the Government of India to control air pollution includes

  1. Permission to use only pure diesel with a maximum of 500 ppm sulphur as fuel for vehicles.

  2. Use of non-polluting 'Compressed Natural Gas (CNG)' only as fuel by all buses and trucks.

  3. Compulsory PUC (Pollution Under Control) certification of petrol driven vehicles, which tests for carbon monoxide and hydrocarbons.

  4. Both B and C.


Correct Option: D
Explanation:

Supreme Court of India, under its directives, asked the government to take appropriate measures, including switching over the entire fleet of public transport, i.e., buses, from diesel to compressed natural gas (CNG). The Government of India through a new auto fuel policy has laid out a roadmap to cut down vehicular pollution in Indian cities. 

More stringent norms for fuels means steadily reducing the sulphur and aromatic content in petrol and diesel fuels. Euro III norms, stipulate that sulphur be controlled at 350 parts-per-million (ppm) in diesel and 150 ppm in petrol. Aromatic hydrocarbons are to be contained at 42 per cent of the concerned fuel. The goal, according to the roadmap, is to reduce sulphur to 50 ppm in petrol and diesel and bring down the level to 35 per cent. Corresponding to the fuel, vehicle engines will also need to be upgraded. It is mandatory for every vehicle owner to carry a valid 'Pollution Under Control' (PUC) certificate, so as to comply with the prescribed emission norms. 

Which of the following stakeholders of forest causes maximum damage ?

  1. People who live in or around the forest

  2. The industries

  3. The wildlife and native enthusiasts

  4. The forest department of the government

Industries release harmful toxic effluents in the environment thus polluting it and impair healthy plant growth. It also occupies forest land and reduces the green cover.

Abatement do not include

  1. Sewage management

  2. Catalytic convetors

  3. Use of scrubbers

  4. All of the above


Correct Option: D
Explanation:

Pollution abatement is the measure to reduce pollution by controlling the direct elimination of pollutants in the environment. It may include technological methods like catalytic converters on vehicles to reduce air pollution, scrubbers in industries or they may be regulatory, like laws limiting the amount of solid waste a sewage management facility can release into a waterway. Thus, the correct answer is option D.

Which of the following is not considered a method of abatement of pollution?

  1. Planting trees along road sides

  2. Greater use of chemical fertilizeres

  3. Treating industrial effluents before discharging them in water bodies

  4. All of the above


Correct Option: B
Explanation:

Pollution abatement is the measure to reduce pollution by controlling the elimination of pollutants in the environment. It can be technological methods like catalytic converters, scrubber and electrostatic precipitator or they may be regulatory, like laws limiting the amount of solid waste a sewage management facility can release into a waterway. Greater use of compost (organic matter) instead of chemical fertilizers and judicious use of pesticides helps in controlling pollution. Thus, the correct answer is option B.

A general time used for methods that reduce the amount of act near brought in

  1. 1981

  2. 1989

  3. 1974
