There are two main types of primary pollutants: man-made pollutants and natural pollutants. Man-made primary pollutants are formed largely from combustion reactions used to create electricity and run the over one billion cars that are in the world today. These pollutants include Sulfur oxides (Sulfur dioxide, Sulfur trioxide), Carbon oxides (Carbon dioxide, Carbon monoxide), and Nitrogen oxides (Nitrogen dioxide, Nitrogen monoxide). Another type of man-made primary pollutant includes VoCs (Volatile Organic Compounds), which are largely responsible for destroying the ozone layer.
Natural primary pollutants are formed by natural disasters such as hurricanes, tornados, and volcano eruptions, and include dust, ash, and salt particles.
secondary pollutants are pollutants that form when primary pollutants react with other primary pollutants or with naturally occurring substances
Some Primary pollutants are like when humans directly put them in the air Secondary pollutants are like when pollutants react with Primary and other Primary pollutants.
secondary pollutants are pollutants that form from chemical reactions that occur when primary pollutants come in contact with other primary polluants or with naturally occurring substances such as water vapor.
Primary pollutants are pollutants that enters the air directly from a source and Secondary pollutants are air pollutantsproduced by the reaction of a primary pollutant with some other pollutant
Primary air pollutants are emitted directly into atmosphere from a process such as exhaust from a engine, industries, volcanic eruption Secondary air pollution are formed in the air when primary pollutants interact.
Ozone and smog are secondary pollutants. They are not primary ones.
Pollution is any foreign substance present in more concentration than safer limits. They are two types of pollutants 1. Primary pollutants 2. Secondary pollutants Primary pollutants are those which generated directly from Source . That type of pollution is generally termed as primary pollution. Ex : Carbondioxide , Sulphur dioxide etc in case of Air pollution Secondary pollutants are those which formed by the combination of more than two or more primary pollutants Ex : Ozone , Photo chemical smog in case of air pollution
the answer to this question is pretty simple and it primary pollutants
Sunlight
Car exhaust
Secondary pollutants. Secondary pollutants are pollutants caused by man. Which consider smog, chemical pollution,ect.. Primary pollutants. primary pollutants are pollutants that are caused by nature. Volcano's eruptions etc. pollution can be caused in the air water sound and any where in the environment
Secondary pollution occurs when primary forms of air pollution, such as vehicle exhaust and factory emissions, interact with each other to form new kinds of pollution. Acid rain, for instance, is a form of secondary air pollution. If you prevent primary pollutants from getting into the atmosphere, you eliminate the ingredients necessary for secondary pollution to occur, thereby creating the secondary effect that these additional pollutants do not form in the first place.
