Cadmium pollution is associated with disease

  1. Itai-itai

  2. Anaemia

  3. Minamata

  4. Pneumoconiosis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Itai-itai is the disease which was caused by the cadmium poisioning due to mining in Toyama Prefecture, Japan. This term was given by the locals for the severe pain the victims felt in the spine and the joints. It can also cause softening of bones and kidney failure. The disease was first described in the menopausal Japanese woman exposed to excessive levels of cadmium over their lifetimes.

Which of the following would be a natural pollution?

  1. Occurence of $NO _2$ in atmosphere

  2. Forest fires

  3. Eutrophication

  4. Occurence of smog
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Due to the increase in the temperature, there can be incidental forests fires. The fires result in the burning of the vegetation and animals. This results in the formation of ash which contains the carbon particles. The fumes of the fire are released in the atmosphere causing air pollution. This is the natural source of air pollution.

Thus, the correct answer is option B.

The two great industrial tragedies, namely MIC and Chernobyl tragedies, respectively occurred where and at which time ?

  1. Bhopal 1984, Ukarine 1990

  2. Bhopal 1984, Ukarine 1988

  3. Bhopal 1984, Ukarine 1986

  4. Bhopal 1986, Russia 1988
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

MIC stands for methyl-isocyanate which is a gas and was leaked accidently in the Union Carbide subsidiary pesticide plant of Bhopal on 3rd dec, 1984 and led to the world's worst industrial disaster.

The Chernobyl tragedy was a nuclear accident that occurred on 26 April 1986 in the No.4 light water graphite moderated reactor at the Chernobyl nuclear power plant near Pripyat, it was then part of the Ukrainian Soviet Socialist Republic of the Soviet Union.
So, the correct answer is option C.

Pollutant gases have an adverse effect on the environment and on our health. The amount of these gases has been steadily increasing over the years. The table given below shows the source and the amount of some pollutant gases produced by human activities.

Pollutant Gas Source Amount Produced per Year(Millions of Tonnes)
$CO _2$ Vehicle exhaust furnaces, burning coal 350
$SO _2$ Oil industries 200
$NO _2$ Vehicles exhaust furnaces 55
Hydrocarbons Vehicle exhaust furnaces, industries 90

Which one of the following statement(s) is correct ?

  1. The total sulphur dioxide and nitrogen dioxide produced per year is 145 million tonnes.

  2. $CO _2$ is produced by industries.

  3. The combined total pollutant gases produced by $NO _2$ and hydrocarbons is less than the total pollutant gases produced by $SO _2$

  4. Hydrocarbons are produced by vehicle exhaust gases and industries.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

NO2 (55) + Hydrocarbons (90) = 145. SO2 = 200. Since 145 < 200, statement C is correct. Statement A is incorrect because 200 + 55 = 255, not 145.

A man made source of air pollution is

  1. Burning of fossil fuels

  2. Dust storm

  3. Pollen grains

  4. Forest fire
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Burning of fossil fuels is a man-made source of air pollution. The various fossil fuels like coal, natural gas, fuel oil are burned by humans for obtaining heat which is used in the generation of electric power. This leads to increase in the concentration of gas emissions like carbon dioxide and sulphur dioxide which enters the atmosphere and leads to air pollution. The increase in the concentration of carbon dioxide causes global warming and sulphur dioxide leads to breathing problem and the major cause of acid rain.

Thus, the correct answer is option 'Burning of fossil fuels'.

Effect of pollution is first and most marked on

  1. Natural flora of a place

  2. Natural geochemical cycle

  3. Natural gaseous cycle

  4. Natural balance of our environment
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Green plants are the producers through which inorganic elements first enter the food chain. Green plants take in elements from the atmosphere, soil and water and manufacture food on which all the other animals either directly or indirectly feed on. Since plants are directly exposed to pollutants, the effect of pollution is first visible in natural flora of a place, then it will be visible on organisms that are dependent on the plants.

Effect of pollution is on

  1. Crossing over

  2. Ecological balance

  3. Linkage

  4. Mutation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Pollution is any change in physical, chemical, or biological characteristics of the environment, that has the potentiality to harm human life, life of other desirable species, natural resources, cultural assets and industries. Pollution affects the atmosphere, hydrosphere and lithosphere by disturbing the delicate balance between abiotic and biotic components and the interaction between various organisms. Thus, the correct answer is option B.

Atmospheric pollutants formed by human activities constitute of the total of

  1. $95\%$

  2. $75\%$

  3. $25\%$

  4. $0.05\%$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water pollution and land contamination, it's the quantity (or concentration) of a chemical in the air that makes the difference between "harmless" and "pollution." Carbon dioxide (CO2), is present in the air around you at a typical concentration of less than 0.05 per cent and breathing it in usually does no harm (you breathe it out all day long); but air with an extremely high concentration of carbon dioxide is toxic and could kill you in a matter of minutes. Since Earth's atmosphere is very turbulent many of us live in windy countries air pollution will often disperse relatively quickly.

So the correct answer is '0.05%'.
