Question

what is smog? how is classical smog different from photo chemical smog? what are the harmful effect of photo chemical smog and how can they be controlled

Answer 1

Smog is a mixture of solid and liquid fog and smoke particles formed when humidity is high and the air so calm that smoke and fumes accumulate near their source. 
The pollutant that is formed by the combination of smoke and fog is called smog. ... Classical smog is a mixture of sulfur dioxide and coal smoke with fog. Photo chemical smoke is a precipitate in the reaction of the nitrogen oxide and other chemical compounds in Sunlight.
The pollutant that is formed by the combination of smoke and fog is called smog. Smog differs in the properties with smoke and fog as well.

There are two types of smog depending upon the type of pollutants present in the atmosphere. The differences between classical smog and photochemical smog are:

Classical smog

Classical smog is a mixture of sulfur dioxide and coal smoke with fog.
The abundance of sulfur in atmosphere causes severe health problems to all the living organisms.
The causes for classical smog are the heavy usage of fuels in industry and household purposes.
This type of smog affects the humans directly. Winter season is predominated by this smog.

Photo chemical smog

Photo chemical smoke is a precipitate in the reaction of the nitrogen oxide and other chemical compounds in Sunlight.
This smog creates an ozone rich pollutants, by the reaction with nitrogen and oxygen in sunlight
Many hazardous secondary pollutants are developed in the reaction of nitrogen oxide, gasoline with Sun light.
There is no particular period for this smog to occur.

EFFECTS OF PHOTOCHEMICAL SMOG:

Photochemical smog is oxidizing smog owing to the presence of,causing corrosion of metals, stones, rubber, and painted surfaces. The other major components of photochemical smog are PAN, acrolein, and formaldehyde. Both PAN and ozone are eye irritants, while nitric oxide (formed from NO2) causes nose and throat irritation. At higher concentrations, photochemical smog causes chest pain, headaches, throat dryness, and various respiratory ailments.

CONTROL MEASURES:

Photochemical smog results from the burring of fossil fuels and automobile fuelsthat emit and hydrocarbons, which in turn form ozone, PAN, and other chemicals. The use of catalytic converters in automobiles is recommended to prevent the release of  and hydrocarbons into the atmosphere.

Plantation of plants such as Pinus, Juniparur, Quercus, Pyrus, and Vitis is also advised as these plants have the capability to metabolize .
