What is the primary pollutant in our atmosphere?
Primary pollutants come directly from sources such as industrial facilities, automobiles and forest fires.
These include sulfur and nitrogen compounds, particulate matter, and toxic metals such as mercury.How do primary air pollutants become part of the atmosphere?
Some particles are primary pollutants that come directly from smokestacks, construction sites, fires, or volcanoes.
However, most are secondary pollutants that form as the result of chemical reactions in the atmosphere due to emissions from power plants, factories, and vehicles.How a primary pollutant becomes part of the atmosphere?
Primary pollutants are released from the combustion of fossil fuels.
Some pollutants (CO, PM) are a result of incomplete combustion of hydrocarbons.
Some pollutants (methane, nitrous oxide, ammonia) are released directly from a biological source, such as cows, swamps, etc.These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.
