Smog is a type of air pollution caused by a number of factors including:
- The burning of fossil fuels
- Power plant emissions
- Vehicular emissions from cars, buses and trucks; the main source of smog in urban areas
- Soot and other pollutants to infiltrate the air
- Hazy sky conditions
- Adverse health effects (see below)
Health Effects Caused by Smog
According to healthcare professionals, ground-level ozone, sulfur dioxide, nitrogen dioxide, and carbon monoxide – all smog components – are a danger to humans. These various forms of air borne pollutants can cause or vex the following health issues in people of all ages:
- Chronic bronchitis
- Eye and nose irritation
- Respiratory infection
How Are Smog and the DMV Related?
Vehicles (especially older models) are the leading cause of smog in metropolitan areas. To combat this problem, many cities, counties, and entire states now require smog tests as part of the car registration process. Your vehicle, if required, must pass a smog inspection before it can be registered (this includes registration renewal, as well).
If your vehicle fails an emissions test, you must have it repaired and re-tested.
How to Improve the Air Quality Around You
There are a few things you can do to reduce the smog in your community:
- Try driving less. Look into carpooling, riding a bike, walking, or opting for public transportation.
- Turn off the car’s engine during idling.
- Take your car in for regular maintenance and get a smog check, even if your state doesn’t require it for vehicle registration.
- Consider buying a hybrid.
