Solution
Harmful effects of photochemical smog:
1) It corrode metals, stones, rubber and painted surface.
2) It causes serious health problems to senior citizens, children and people with heart and lung problems which lead to emphysema, bronchitis, asthma.
3) It causes pneumonia, inflammation of pulmonary tissues, fatigue, heart palpitations, premature aging of lungs and death.
Control measures:
1) The release of NO2 and hydrocarbons in the atmosphere can be prevented by using catalytic converters.
2) Switching over to other types of fuels, desulfurization of fuel gases from coal fired power plants, expansion of public rail transport.
3) Since plants can metabolize NO2, Pinus, Juniparur, Quercus, Pyrus and Vitis should be planted.
