Answers
Answer:
Air pollution occurs when harmful or excessive quantities of substances including gases (such as carbon dioxide, carbon monoxide, sulphur dioxide, nitrous oxides, methane and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules are introduced into Earth's atmosphere.
Explanation:
Effects of air pollution
A variety of air pollutants have known or suspected harmful effects on human health and the environment. In most areas of Europe, these pollutants are principally the products of combustion from space heating, power generation or from motor vehicle traffic. Pollutants from these sources may not only prove a problem in the immediate vicinity of these sources but can travel long distances.
The table below shows the types of health effects experienced by the most common pollutants at elevated levels:
Pollutant Health effects at very high levels
Nitrogen Dioxide, Sulphur Dioxide, Ozone These gases irritate the airways of the lungs, increasing the symptoms of those suffering from lung diseases
Particles Fine particles can be carried deep into the lungs where they can cause inflammation and a worsening of heart and lung diseases
Carbon Monoxide This gas prevents the uptake of oxygen by the blood. This can lead to a significant reduction in the supply of oxygen to the heart, particularly in people suffering from heart disease
