Smog
Smog is a kind of air pollution, originally named for the mixture of smoke and fog in the air.
Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide.
In the 1950s a new type of smog, known as Photochemical Smog, was first described.
Smog is a problem in a number of cities and continues to harm human health.
Ground-level ozone, sulfur dioxide, nitrogen dioxide carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma.
It can inflame breathing passages, decreasing the lungs' working capacity, and causing shortness of breath, pain when inhaling deeply, wheezing, and coughing.
It can cause eye and nose irritation and it dries out the protective membranes of the nose and throat and interferes with the body's ability to fight infection, increasing susceptibility to illness.
Hospital admissions and respiratory deaths often increase during periods when ozone levels are high.
