Air pollution: how does it affect your health?
These days many people are concerned about air pollution and whether it might affect their health. The fact is that most of the time, air pollution levels in East Hampshire are low. The air is certainly a lot cleaner today than in the days of the smogs and pea soups of the 1950’s, when factory chimneys belched out smoke and nearly everyone had a coal fire.
This doesn't mean we shouldn't care about air pollution. Some people are more likely that others to be affected by changes in air quality. People who have lung and heart conditions, the very young and very old people are at more risk from changes in the air quality.
How does air pollution affect health?
Pollutant
|
Sources
|
Health effects at very high levels
|
| Carbon monoxide |
Incomplete combustion of fossil fuels. |
Carbon monoxide prevents the normal transport 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. Can cause death. |
| Benzene |
Vehicle emissions, evaporation of petrol during vehicle fuelling and from fuel tanks, fossil fuel combustion. Benzene also occurs naturally.
|
Excessive exposure may affect the blood, brain, heart, immune system, liver, lung and skin and in worse cases benzene can cause cancer. |
| 1, 3-butadiene |
Vehicles emissions, chemistry industry |
Genetic damage, breathing difficulties and cancer. |
| Lead |
Industry emissions |
Brain damage, kidney problems, collapse of nervous systom, damage to reproductive organs. In worse cases can lead to death. |
| Nitrogen dioxide |
Vehicles, burning fossil fuels, power stations. |
Irritates the airways of the lungs, increasing the symptoms of those suffering from lung diseases. Bacterial infections. |
| Sulphur dioxide |
Burning fossil fuels, especially coal, industry. |
Irritates the airways of the lungs, increasing the symptoms of those suffering from lung diseases. |
| Particles (PM10) |
Industrial activities, combustion of wood and fossil fuels, construction and demolition activities, movement of road dust into the air. Road vehicles. PM also occurs naturally. |
Fine particles can be carried deep into the lungs where they can cause inflammation and a worsening of heart and lung diseases. Research is still being carrie dout to establish the true effect of particles on human health. |
| Ozone |
Ozone is created by a photochemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOCs) in the presence of sunlight. |
Irritates the airways of the lungs, increasing the symptoms of those suffering from lung diseases. |
