Detailed explanation-1: -Carbon monoxide (CO) is a colorless, odorless gas. It results from the incomplete combustion of carbon-containing fuels such as natural gas, gasoline, or wood, and is emitted by a wide variety of combustion sources, including motor vehicles, power plants, wildfires, and incinerators.
Detailed explanation-2: -EPA has established national ambient air quality standards (NAAQS) for six of the most common air pollutants-carbon monoxide, lead, ground-level ozone, particulate matter, nitrogen dioxide, and sulfur dioxide-known as “criteria” air pollutants (or simply “criteria pollutants”).
Detailed explanation-3: -The six criteria pollutants are carbon monoxide, ground-level ozone, lead, nitrogen dioxide, particulate matter, and sulfur dioxide.
Detailed explanation-4: -Hence we can say carbon dioxide is not considered to be six major pollutants according to the EPA of the USA.
