Definition - What does Air Quality mean?
Air quality is the term used to refer to the level of pollutants in the air. Good or clean air is needed for optimum health for humans, animals and vegetation. Air quality can be compromised in industries, such as shipping ports, where diesel and fossil fuels are readily used. If air quality is greatly compromised, this poses a risk to human health.
Safeopedia explains Air Quality
The makeup of many pollutants changes when released into the air. This is because they meet and react with other pollutants. These pollutants can also undergo a molecular change when they encounter extreme heat, wind or rain.
A common misconception is that air quality can be tested by sight. If the air is smoggy from dust and smoke this automatically signals a low quality air level. However, many gases released into the air are clear and, which also result in a low air quality level, are undetectable with the human eye.
