Yes it is emitted directly from the milling.
No, formaldehyde is not considered a primary pollutant. It is a secondary pollutant that forms in the atmosphere as a result of chemical reactions involving primary pollutants such as volatile organic compounds (VOCs) and nitrogen oxides.
No. Hydrocarbon is a Primary pollutant.
(saw) dust
Mostly HNO3 (Hydro nitrogen trioxide) this is the main one and also along with CO1/2/3 SO1/2/3 which are Carbon,Monoxide, Dioxide, Trioxide and Sulfur Monoxide, Dioxide, Trioxide.Hope this helped. Varian Wyrnn.
yes
Primary polluters are air pollutants that come directly from a source. A volcanic eruption is an example of a primary pollutant.
No, carbon monoxide (CO) is not considered a primary pollutant. It is a secondary pollutant that forms from the incomplete combustion of fossil fuels and is primarily produced by vehicles and industrial processes.
Ozone is not a primary pollutant. It is formed in the atmosphere as a secondary pollutant through reactions involving primary pollutants like nitrogen oxides and volatile organic compounds in the presence of sunlight.
Air is primary agent
secondary pollutant. deals with oxygen in air
Yes
secondary pollutant because of the it extracts a gas / smoke that contributed to global warming .
