Someone else does!
We have all driven behind an old vehicle (or diesel truck) that gives off a lot of “smell” and soot/ fumes…. and you do not want to breath those smells either, they are toxic!
Fortunately vehicles do not last forever, and the vehicles that replace old ones are almost always much cleaner (in terms of their operating emissions). That said, even the cleanest vehicles emit something dirty and toxic… tire dust for example is released by fuel cell and electric vehicles the same way that tire dust is released by conventional vehicles. Smog brings to mind places like Mexico City, Beijing China, and Los Angeles California. Smog is a soup of funky toxic chemicals suspended in the air. Soot from diesel engines and coal power plants, that fine particulate matter that causes asthma, lung cancer and chronic obstructive pulmonary disorder; known as PM, it is a major component of urban smog. Have you ever found yourself asking: “where is the closest station for smog check near me?”

PM

Particulate Matter, the fine dust/ soot released from the incomplete combustion of fuels / the dark funk you see emitted from diesel trucks and buses and older diesel passenger cars. Due to the health effects of particulate matter, various governments have created regulations both for the emissions allowed from certain types of pollution sources (motor vehicles, and for the ambient concentration of particulates. Many urban areas in the U.S. and Europe still frequently violate the particulate standards because of the over-use of private and commercial vehicles. You may start wondering again, “where is that station for smog check near me?

Irritating ground level ozone that disturbs the mucus membranes in our eyes, mouths and lungs. It forms when VOC and HC emissions (fuel vapor fumes) bake in the sunlight, where the UV energizes chemical reactions that form Ozone.

VOC’s from fuel that exits tailpipes un-burned (incomplete combustion). People literally huff on fuel vapors to get high breathing in VOC’s. Sadly, we are all exposed to persistent low levels of these same chemicals from traffic corridors. Un-burned gasoline vapors exit the exhaust of a vehicle as HC or hydro-carbon, a regulated air pollutant. We all breath these fumes, some of us more than others, and it is the daily low level exposure over long periods of time that causes the negative health problems associated with breathing in transportation emissions or smog. After becoming aware of this dangerous effect, you may be asking yourself: “where is a station for smog check near me?”
