The cost to your health
Air pollution occurs when solid and liquid particles as well as some gases become suspended in the air, these suspended elements are called aerosols. When the concentration of these aerosols becomes too high, air quality decreases. These particles can sometimes be large enough to see, for example in smoke or smog, however most cannot be seen by the naked eye. Exposure to air pollution in the form of PM2.5, smog, dust or smoke is hugely detrimental to your health. Such exposure can cause lasting respiratory problems and can worsen or trigger illnesses such as asthma, chronic bronchitis, strokes and heart attacks.
