Detailed explanation-1: -Apparently, this is a logically depiction given that the main source of industrial smog was from the burning of coal for heat and energy (Nebel and Wright 527). As a result, the main pollutant of industrial smog is sulfur dioxide-a compound largely responsible for acid precipitation.

Detailed explanation-2: -While industrial smog’s primary pollutants of coal and fossil fuels mixing with dense water vapor are widely understood, the creation of secondary pollutants–the ones created when primary pollutants react with substances normally found in the atmosphere–is the root of most of the human health problems.

Detailed explanation-3: -Photochemical smog is made up of various secondary pollutants like ozone, peroxyacyl nitrates (PANs), and nitric acid (seen in Figure 2). Different types of secondary pollutants include: Ozone (O3)

Detailed explanation-4: -Secondary pollutants The secondary pollutant that causes the most concern is the ozone that forms at ground level. While ozone is produced naturally in the upper atmosphere, it is a dangerous substance when found at ground level. Many other hazardous substances are also formed, such as peroxyacetyl nitrate (PAN).
