Smog comprises many small particles, including ozone, pollens, topsoil, wood smoke, nitrogen dioxide, nitrogen oxides, organic compounds, hydrocarbons, road dust, heavy traffic, high temperatures, the sunshine and calm winds. Smog is a yellowish or blackish fog that negatively affects both the environment and human health. Sometimes it can make breathing very difficult. It creates a hazy environment across the city, which makes complications in visualization.

    I am glad you mentioned that smog can cause breathing problems. We have pretty bad air quality where I am from and most of the people who live here have asthma. Thanks for the information on the effects of smog on the environment and your health.

    It caught my attention when you said smog contains toxic chemicals that when inhaled can affect the respiratory system in a negative way. If that is the case, then there is a reason why in California, smog testing is very important. I will have to take its side since I have kids that I want to protect. Because of this, I will encourage everyone to undergo smog testing.
