What is smog?
To explain what smog is, we need to mention that the term is actually a combination of two words: smoke and fog. It was coined at the beginning of the 20th century. It’s air pollution that can be produced both naturally and artificially. In the past, it was observable only in industrial areas, but a lot has changed since then. Car exhaust fumes, and wood stove burning are only two sources of smog in smaller cities, or villages. Where does smog come from?
Where does smog come from?
Wondering what is the main ingredient in smog? Smog is a combination of primary and secondary pollutants, meaning ozone, and nitrogen oxides. So, where does smog come from?
Ozone
Ozone is a greenhouse gas that can be extremely dangerous at ground level. It’s the main ingredient of smog, created when volatile organic compounds and nitrogen oxides interact with sunlight.
Particulate matter
Particulate matter is made of liquid droplets and solid particles. Usually, it’s microscopic and isn’t visible to the naked eye. It’s emitted mainly during combustion and as a result of chemical reactions with VOCs.
The impact of smog on health
Now you know what is smog, but let’s focus on how long-term exposure to harmful substances and air pollutants like smog can have very negative health consequences. It may lead to:
-
- Asthma,
- Problems with concentration,
- Respiratory and circulatory problems,
- Nausea,
- Persistent cough,
- Strokes,
- Heart attacks,
- Cancer,
- Premature death.
As you can see, the smog effects on your health can be serious. For this reason, it’s worth taking the measures to limit your exposure to harmful substances. If you want to keep an eye on the air quality and pollution levels, you should choose popular solutions like sensors or apps and maps that are available for free and show air quality data in real-time.
If the air quality isn’t satisfactory, it’s better to resign from outdoor activities if possible and choose public transportation. Such small gestures can make a difference.
The takeaway
Smog is a dangerous substance that can cause serious health conditions. It’s created when volatile organic compounds and nitrogen oxides interact with sunlight. Using available tools and solutions for air quality monitoring can help you limit your exposure to harmful compounds.
