Across many major cities, a hazy brown soup of pollution hangs over the skyline, especially in the warmer months. This is smog, known more specifically as ground-level ozone.
Smog is formed when industrial emissions from power plants, factories, cars, and other sources react with heat and sunlight in the atmosphere.
When inhaled, smog irritates our airways, increasing our risk of serious heart and lung diseases. These health risks are why many cities monitor smog levels. On a high ozone-alert day, for example, your eyes and throat may burn, and you may cough and wheeze.
Smog is a nuisance in many places. Everyone can play a role in eliminating smog by adopting just a few habits, such as using electrical appliances instead of gas appliances, driving less, walking more, taking care of your car, changing the oil from time to time and Keep tire levels constant. The above precautions can reduce smoke emissions.
