Even short-term exposure to photochemical smog tends to have ill effects on both the young and the elderly. It causes painful irritation of the respiratory system, reduced lung function and difficulty breathing; this is more evident while exercising or working outdoors.

One of the main pollutants in smog that causes health effects is tropospheric ozone. At low concentrations, ozone is an irritant, hurting the eyes, nose, and throat. At higher concentrations it can worsen respiratory conditions such as asthma, bronchitis, coughing, and chest pain.

Moreover, What is photochemical smog and what are its harmful effects?

Even short-term exposure to photochemical smog tends to have ill effects on both the young and the elderly. It causes painful irritation of the respiratory system, reduced lung function and difficulty breathing; this is more evident while exercising or working outdoors.

What are the effects of smog on human health?

Smog can irritate your eyes, nose and throat. Or it can worsen existing heart and lung problems or perhaps cause lung cancer with regular long-term exposure. It also results in early death. Studies on ozone show that once it gets into your lungs, it can continue to cause damage even when you feel fine.
