#1. Which of the following statements about ozone is correct?

Stratospheric ozone protects us from UV radiations

Tropospheric ozone protects us from UV radiations

Stratospheric ozone is ‘bad’

Tropospheric ozone is ‘good’

Ozone, in our atmosphere is found in two layers 1. Stratosphere – good ozone, protects us from UV radiations 2. Troposphere – bad ozone, considered as a pollutant.

#2. Which of the following is an innovative remedy for plastic waste?

Electrostatic precipitator

Burning in the absence of oxygen

Burying 500 m deep below soil surface

Polyblend

Polyblend is fine powder of recycled plastic waste that after mixing with bitumen, used to lay roads.

#3. If an agricultural field is liberally irrigated for a prolonged period of time, it is likely to face a problem of

Salinity

Metal toxicity

Alkalinity

Acidity

#4. Which of the following pairs of gases is mainly responsible for green house effect?

Ozone and Ammonia

Oxygen and Nitrogen

Nitrogen and Sulphur dioxide

Carbon dioxide and Methane

#5. Which of the following protocols did aim for reducing emission of chlorofluorocarbons into the atmosphere?

Montreal Protocol

Kyoto Protocol

Gothenburg Protocol

Geneva Protocol

To control the deleterious effect of the stratospheric ozone depletion an international treaty was signed at Montreal, Canada in 1987.

#6. Polyblend, a fine powder of recycled modified plastic, has proved to be a good material for

Making plastic sacks

Use as a fertilizer

Construction of roads

Making tubes and pipes

#7. Which of these following methods is the most suitable for disposal of nuclear waste?

Shoot the waste into space

Bury the waste under Antarctic ice-cover

Dump the waste within rocks under deep ocean

Bury the waste within rocks deep below the Earth's surface

Storage of nuclear waste should be done in suitably shielded containers and buried within rocks deep below the earth’s surface (500 m deep)

#8. In stratosphere, which of the following elements acts as a catalyst in degradation of ozone and release of molecular oxygen?

Carbon

Oxygen

UV rays act on CFCs, releasing Cl atoms, chlorine reacts with ozone in sequential method converting into oxygen

Carbon, oxygen and Fe are not related to ozone layer depletion

#9. Which of the following is a secondary pollutant?

CO₂

SO₂

O₃

O3 (ozone) is a secondary pollutant. These are formed by the reaction of primary pollutant.

CO – Quantitative pollutant

CO2 – Primary pollutant

SO2 – Primary pollutant

#10. World Ozone Day is celebrated on

5th June

21st April

21st September

16th September

#11. A lake which is rich in organic waste may result in

Increased population of aquatic organisms due to minerals

Drying of the lake due to algal bloom

Increased population of fish due to lots of nutrients

Mortality of fish due to lack of oxygen

Micro-organisms involved in biodegradation of organic matter consume oxygen as a result there is a sharp decline in oxygen causing mortality of fish and other aquatic creatures.

#12. The highest DDT concentration in aquatic food chain shall occur in

Phytoplankton

Seagull

Crab

Eel

Maximum DDT concentration occurs in fish eating birds like Seagull due to biomagnification. This happens because a toxic substance accumulated by an organism cannot be metabolised or excreted, thus passed to higher trophic level.

#13. A river with an inflow of domestic sewage rich in organic waste may result in

Death of fish due to lack of oxygen

Drying of the river very soon due to algal bloom

Increased population of aquatic food web organisms

An increased production of fish due to biodegradable nutrients

A river with an inflow of domestic sewage rich in organic waste will reduce the dissolved oxygen (DO) and may result in death of fish due to lack of oxygen.

#14. Joint Forest Management Concept was introduced in India during

1980

1970

1979

1967

Joint Forest Management Concept was introduced in India during 1980s by the Government of India to work closely with the local communities for protecting and managing forests.

#15. Eutrophication of water bodies leading to killing of fishes is mainly due to non-availability of

Oxygen

Food

Light

Essential minerals

BOD level increases due to rapid growth of microbes.

#16. Acid rain is caused by increase in the atmospheric concentration of :

O₃ and dust

SO₂ and NO₂

SO₃ and CO

CO₂ and CO

#17. Increase in concentration of the toxicant at successive trophic levels is known as:

Biogeochemical cycling

Biomagnification

Biotransformation

Biodeterioration

#18. The UN conference of Parties on climate change in the year 2012 was held at

Warsaw

Durban

Doha

Lima

#19. High value of BOD (Biochemical Oxygen Demand) indicates that

Consumption of organic matter in the water is higher by the microbes

Water is pure

Water is highly polluted

Water is less polluted

indirect measure of the organic matter present in the water.

#20. Rachel Carson's famous book "Silent Spring" is related to

Ecosystem management

Pesticide pollution

Noise pollution

Population explosion

#21. A scrubber in the exhaust of a chemical industrial plant removes

Gases like sulphur dioxide

Particulate matter of the size 5 micrometer or above

Gases like ozone and methane

Particulate matter of the size 2.5 micrometer or less

#22. A location with luxuriant growth of lichens on the trees indicates that the

Trees are very healthy

Trees are heavily infested

Location is highly polluted

Location is not polluted

#23. The zone of atomosphere in which the ozone layer is present is called

Ionosphere

Mesophere

Stratosphere

Troposphere

#24. Eutrophication is often seen in:

Mountains

Deserts

Fresh water lakes

Ocean

#25. dB is a standard abbreviation used for the quantitative expression of

A certain pesticide

The density of bacteria in a medium

A particular pollutant

The dominant Bacillus in a culture

Unwanted sound is called noise and it is measured in terms of decibels (dB). Generally sound above 80 dB is noise.
