Questions Related to air pollution and its effects
ESP is to arrest
-
Water Pollution
-
Air Pollution
-
Radio Activity Pollution
-
Soil Pollution
ESP or electrostatic precipitators are used to remove dust particles from flue gas (such as gas from broilers). The dust particles present in the air get charged as they pass through the electrostatic precipitator and get collected at the collection electrode. It can, therefore, be used to remove air pollutants such as dust.
Which gas is supposed to be the main gas responsible for air pollution?
-
$SO _2$
-
$CO _2$
-
$CO$
-
$O _2$

-
50%
-
70%
-
80%
-
100%
Vehicle emissions are responsible for 70% of the country's air pollution. Exhaust from vehicles has increased eight-fold over levels of twenty years ago. Air quality is worst in big cities like Kolkata, Delhi, Mumbai, Chennai, etc.
Air pollution is caused by
-
Smoke
-
Automobile exhausts
-
Radioactive substances
-
All of the above
Air pollution can be defined as the mixing of harmful gases or chemical substances in the air, that results into harmful effects on flora as well as fauna. The major pollutants of air pollution includes the harmful untreated gases that are released into the atmosphere from factories, also the carbon monoxide gas released from the burnt fuel in the automobiles. Sometimes the leakage of radioactive substance also led to adverse effects on living organism.
Air pollution is maximum due to
-
Sewage and pesticides
-
Automobile exhausts and industrial wastes
-
Sewage and effluents
-
Detergents and pesticides
Burning of fossil fuels leads to their combustion causing the release of carbon dies oxide in air. It also releases other harmful gases that cause air pollution. So, option B " Automobile exhausts and industrial wastes" is the correct answer.
The air around us has various types of unwanted particles, such as
-
Smoke
-
Dust
-
Pollens
-
All of the above
The air around us has various types of unwanted suspended particles like- smoke, dust, pollens etc. When we inhale these particles get trapped in the hair present in our nasal cavity. However, sometimes these particles may get past the hair present in our nasal cavity. Then they irritate the lining of the cavity as a result of which we sneeze. Sneezing expels these foreign particles from the inhaled air and a dust-free, clean air enters our body.
