Detailed explanation-1: -Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. VOCs are released from gasoline, paints, and many cleaning solvents.
Detailed explanation-2: -Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight.
Detailed explanation-3: -Smog, the primary constituent of which is ground level ozone, is formed by a chemical reaction of carbon monoxide, nitrogen oxides, VOCs, and heat from sunlight.
Detailed explanation-4: -Smog is a form of air pollution. The word “smog” is a combination of the words “smoke” and “fog.” Smog is a mixture of many pollutants, mainly ground level ozone and fine particulate matter. Sources of smog include: barbecues. coal-fired power generation stations.
Detailed explanation-5: -Carbon Monoxide (CO) Most of the carbon monoxide pollution comes from burning fossil fuels in vehicles, factories, and power plants, but another major source is from burning wood or crop waste. Carbon monoxide is released from volcanoes and forest fires as well.
