Step 2: Provide Examples of Primary PollutantsExamples of primary air pollutants include:- Particulates (such as dust, soot, and smoke)- Carbon monoxide (CO)- Nitrogen oxides (NO and NO2)- Sulfur oxides (SO2) Step 3: Define Secondary PollutantsSecondary pollutants are not emitted directly. Ins...
The question to what extent primary and secondary air pollutants are relevant to atmospheric pollution and their effects on human health and the quality of the environment can be answered in a straight-forward manner: atmospheric processes, including oxidation procedures, particle formation and ...
In this communication, we review recent activities and trends of primary and secondary air pollutants in the state of Kuwait, a country associated with petroleum, petrochemical, and other industrial pollution. Trends of pollutants and impact on human health have been studied and categorized based on...
In addition, many cleaning agents and air fresheners contain chemicals that can react with other air contaminants to yield potentially harmful secondary products. For example, terpenes can react rapidly with ozone in indoor air generating many secondary pollutants, including TACs such as formaldehyde. ...
