Q5.Which one of the chemical is responsible for the reduction of ozone content of the atmosphere?
Solution
Ozone protects us from the harmful UV radiations from the sun. Major pollutants responsible for the depletion of ozone layer are chlorofluorocarbons, nitrogen oxides and hydrocarbons CFCs are widely used as coolants in air conditioners and refrigerators, cleaning solvents, aerosol propellants and in foam insulation. The threat to O_3 is mainly from CFCs, which are known to deplete O_3 by 14% at the current emission rate

Q10. Photochemical smog pollution does not contain
Solution
Some sulphates and nitrates can also be formed in photochemical smog due to oxidation of sulphur containing components (SO_2,H_2 S) and NO_x (N_2 O_5,NO_2) but it does not contain CO_2. Photochemical smog materials cause damage to plants, human health hazards and corrosion problems.
