Approach Solution -2

Photochemical smog is most likely to be found in sunny desert areas. This is because photochemical smog is formed due to the reaction of nitrogen oxides and volatile organic compounds in the presence of sunlight. Sunny and warm climates with high levels of automobile traffic and industrial activity tend to have higher levels of nitrogen oxides and volatile organic compounds, which can contribute to the formation of photochemical smog. Desert areas with high levels of traffic and industrial activity are particularly susceptible to photochemical smog because they receive high levels of sunlight and have stagnant air conditions that trap pollutants.

Environmental Pollution

When there is an unpleasant change in the surrounding that has harmful effects on plants and animals, it leads to environmental pollution. Pollution is the root cause of a substance - “pollutant”. We can have pollutants in solid, liquid, or gaseous forms. A substance becomes a pollutant when its concentration is greater than the natural abundance and this increase in concentration is either because of human activities or natural phenomena.

Effects of Environmental Pollution:

Some pollutants are scraped into the soil by human beings. This leads to air, water, and soil pollution. If the soil is polluted, the helpful or functional microorganisms in it will die and the fertility of the soil will vanish. The production of crops will diminish. If the soil is not fertile; it will have a harmful consequence on human society.
