Detailed explanation-1: -Nitrogen dioxide is a deep red-orange gas that is poisonous but not flammable. It, along with aerosols, is responsible for the reddish-brown color of smog. At high concentrations it is highly toxic, and can cause serious lung damage.

Detailed explanation-2: -Photochemical smog is formed when the pollutants in air react with the sunlight. The sunlight converts the pollutants into chemicals. So when sunlight reacts with nitrogen oxide in atmosphere, the smog is produced which is visible as a brown haze specially during morning and afternoon.

Detailed explanation-3: -Reddish-brown smog: nitrogen oxides Nitrogen oxides (NOx), a colorless, toxic gas that comes from combustion of oil, coal, and gas.

Detailed explanation-4: -Nitrogen dioxide (NO2) is a highly toxic, reddish brown gas that is formed through the oxidation of nitric oxide (NO) emitted primarily from the combustion of fuels in stationary or transportation sources.

Detailed explanation-5: -Photochemical Smog. Photochemical smog, as commonly seen in the Los Angeles Basin, is mainly composed of ozone and nitrogen dioxide.
