Heat islands are formed by

  1. Water pollution

  2. Air pollution

  3. Land pollution

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The heat island is a phenomenon where heat can no longer escape. The high temperature in urban areas as compared to rural areas can be called heat island effect. With the loss of vegetation and land surface in urban areas, heat gets trapped between buildings and dense areas which cause a warming effect. The air pollution due to greenhouse gases is responsible for this. Bigger cities have large heat island effects, the waste heat from energy use, seasonal changes, local weather also contribute to heat islands.

Hence, the correct answer is 'Air pollution'.

Sulphurous smog is

  1. Photochemical smog

  2. Oxidising smog

  3. Classical smog

  4. Los Angeles smog
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Smog is the fog containing smoke. Smog is of two types depending upon the type of pollutants; classical smog and photochemical smog.
  • Classical smog, also known as London smog or Sulphurous smog, is formed when there is high concentration of sulphur dioxide and particulate matter produced due to combustion of fuels. It occurs in cold and humid climate and has reducing nature.
  • Photochemical smog, also known as Los Angeles smog, is formed when sunlight acts on the oxides of nitrogen and hydrocarbons produced from factories or by automobiles. It occurs in warm and dry climate and has oxidising nature.
So, the correct answer is 'Classical smog'.

Smog that occurs due to low temperature and has reducing environment is

  1. Photochemical smog

  2. Los Angeles smog

  3. Nonsulphurous smog

  4. London smog

D Correct answer
Explanation
Smog is the fog containing smoke. Smog is of two types depending upon the type of pollutants; classical smog and photochemical smog.
  • Classical smog, also known as London smog or Sulphurous smog, is formed when there is high concentration of sulphur dioxide and particulate matter produced due to combustion of fuels. It occurs in cold and humid climate and has reducing nature.
  • Photochemical smog, also known as Los Angeles smog, is formed when sunlight acts on the oxides of nitrogen and hydrocarbons produced from factories or by automobiles. It occurs in warm and dry climate and has oxidising nature.
Hence, the smog that occurs due to low temperature i.e. in cold climate, and has reducing environment is classical smog or London smog.
So, the correct answer is 'London smog'.

Annual number of deaths in Delhi believed to be due to air pollution is

  1. 1000

  2. 5000

  3. 7500

  4. 15000
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Motor vehicle emissions are one of the causes of poor air quality. Other causes include wood-burning fires, fires on agricultural land, exhaust from diesel generators, dust from construction sites, burning garbage and illegal industrial activities in Delhi.
  • Air pollution exposure can trigger new cases of asthma, exacerbate (worsen) a previously-existing respiratory illness, and provoke development or progression of chronic illnesses including lung cancer, chronic obstructive pulmonary disease, and emphysema. If untreated result in death.
  • An annual number of deaths in Delhi believed to be due to air pollution is 7500.
  • So, the correct answer is '7500'.

Which of the following causes degradation of RBS?

  1. Hydrocarbons

  2. Sulphur compounds

  3. Ammonia

  4. Arsenic compounds
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Arsine is the simplest compound of arsenic. It is colourless and 2.5-times denser than air, with an odour resembling garlic. Arsine binds to haemoglobin of the red blood cells, destroying them. Arsenic disrupts ATP production. Arsenic inhibits pyruvate dehydrogenase, uncoupling oxidation phosphorylation. Arsenic poisoning also occurs through arsenic–oxygen compounds, especially arsenic trioxide, As2O3 (ATO), which is 500-times more toxic than pure arsenic. 
Hence, the correct answer is ' Arsenic compounds'.

3, 4-benzopyrene causes 

  1. Leukaemia

  2. Cytosilicosis

  3. Lung cancer

  4. Tuberculosis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

There are a number of chemicals, which causes lung cancer and one of them is 3, 4- benzopyrene. Benzopyrene mutates three key positions in the p53 gene, which leads to lung cancer. Hence, the correct answer is option C.

Which pollution is considered as major environmental risk factor on environment?

  1. Visual pollution

  2. Therml pollution

  3. Soil pollution

  4. Air Pollution
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Air pollution is widely recognized as one of the most significant environmental risk factors globally, causing millions of premature deaths annually through respiratory and cardiovascular diseases. While visual, thermal, and soil pollution are serious concerns, air pollution has the broadest and most direct impact on human health and ecosystems globally. The WHO identifies air pollution as the largest environmental health risk.

Nitrogen oxides produced from the emission of automobiles and power plants, are the source of fine particles, which lead to

  1. Phochemical smog

  2. Dry acid deposition

  3. Industrial smog

  4. Wet acid deposition

  5. Both B and D
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Acid rain is a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Sulfur dioxide ($SO _2$) and nitrogen oxides (NOx) are the principal pollutants, that cause acid precipitation. $SO _2$ and NOx emissions released to the air react with water vapor and other chemicals to form acids that fall back to earth. The majority of NOx comes from cars, buses, trucks, and other forms of transportation and from power plants. Therefore, the correct answer is option E.

Osteoporosis will be caused by pollutant 

  1. Chlorine

  2. Bromine

  3. Fluorine

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Skeletal fluorosis or osteoporosis is a bone disease caused by excessive accumulation of fluoride in the bones. In advanced cases, skeletal fluorosis causes pain and damage to bones and joints. Due to a high fluorine concentration in the body, the bone is hardened and thus less elastic, resulting in an increased frequency of fractures. Other symptoms include thickening of the bone structure and accumulation of bone tissue, which both contribute to impaired joint mobility. Ligaments and cartilage can become ossified. As a result, bone flexibility decreases making the bone more amenable to fractures.
