Document Summary
Effects of smog: effects on human health. Smog is composed of a mixture of air pollutants which can endanger human health. Various human health problems such as emphysema, asthma, chronic bronchitis, lung infections, and cancers are caused or exacerbated by the effects of smog. Coughing and irritation of the eyes, chest, nose and throat: high ozone levels can irritate the respiratory system leading to coughing and wheezing. These effects generally last for only a few days after exposure, but the particles in the smog can continue to damage the lungs even after the irritations disappear. Aggravation of asthma: asthma conditions are severely worsened by smog and can trigger asthma attacks. Breathing difficulties and lung damage: bronchitis, pneumonia, and emphysema are some of the lung conditions linked to the effects of smog as it damages the lining of the lungs. Smog also makes it difficult for people to breathe properly.
