If an airport is engulfed with smog, the flights have to be cancelled or diverted as smog will reduce the visibiliy very much.

Answer 4

Smog is a kind of air pollution; the word "smog" is a portmanteau of smoke and fog. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulphur dioxide.

Smog is a problem in a number of cities and continues to harm human health.[1] Ground-level ozone is especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma[2]. 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 [3].

An erupting volcano can also emit high levels of sulphur dioxide, creating volcanic smog, or vog.

The burning of forests in Indonesia has on a number of occasions created prolonged smog-like haze, which have extended to parts of Malaysia, Philippines, Singapore and Thailand although a lot of the times these fires are started by farmers who want to clear away land for the start of the new planting season.
