345088 Automobiles are a major cause for atmospheric pollution atleast in the metro cities. How do we control it?

345089 A scrubber in the exhaust of a chemical industrial plant removes

345090 Which method is used to remove particulate matter present in exhaust of thermal power plant?

345091 Select the correct statement
I. Automobiles are a major cause for atmospheric pollution atleast in the metro cities.
II. Proper maintenance of automobiles along with use of plumbum-free petrol or diesel can reduce the pollutants they emit.
III. Catalytic converters, use expensive metals namely platinum-polonium and rhodium as the catalysts
IV. Unburnt hydrocarbons are converted into carbon dioxide and water, and carbon monoxide and nitric oxide are changed to carbon dioxide and nitrogenoxide gas, respectively.
V. Motor vehicles equipped with catalytic converter should use unleaded petrol because lead in the petrol activates the catalyst

345092 What are the measures we need to enforce to protect ourselves from noise pollution.
a. Stringent following of laws laid down in relation to noise
b. Delimitation of horn-free zones around hospitals and schools
c. Permissible sound-levels of crackers and of loudspeakers
d. Strict timings after which loudspeakers cannot be played
