What is air quality and how does it affect us

Air quality refers to the amount of air pollution present in the air. Air pollution is a mixture of substances, including dust, dirt, soot, smoke and liquid droplets. The main sources of air pollution are transport, energy production and industry. Air quality can be measured by observing different factors which can be divided into two groups – particles or gases.

How do we measure air quality

Air quality can be measured by observing different factors which can be divided into two groups – particles or gases. The two most common ways to measure air quality are by measuring the level of concentrations of particles in the air, or by measuring the level of gases in the air.

The first way is to measure concentrations of particles in the air. Generally, particle concentrations are monitored over 24 hours. Results are compared with the limit values set by the World Health Organisation WHO for short term exposure, which are 10 micrograms per cubic metre for particulate matter smaller than 10 micrometres in diameter PM10, and 20 micrograms per cubic metre for particulate matter smaller than 2.5 micrometres in diameter PM2.5.

The second way is to measure the level of gases in the air. The most common gas measured is carbon dioxide, which is emitted by vehicles and industry. This form of measurement involves recording the concentration over a long period of time, usually at least 24 hours. If concentrations are higher than they should be, authorities will take steps to reduce them if necessary.

How does weather affect air quality

According to studies, there is strong evidence that shows how high levels of humidity can decrease the amount of pollutants in the air while wind speeds increase it because it blows pollutants away from their area where people live and work into other areas such as forests or agricultural land. During foggy or misty conditions, some contaminants may stay in air longer than they would during clear conditions.

Ways to improve your home’s indoor or outdoor environment for better health and well-being

It is important to maintain a healthy environment in your home, whether it’s indoor or outdoor. The following are five ways you can improve your home’s indoor or outdoor environment for better health and well-being:

1) reduce toxic heavy metals by not using pesticides;

2) make sure your pets are vaccinated;

3) make sure the water you drink is free of contaminants;

4) avoid air pollution by not burning things like coal on stoves;

5) wear a mask when outside to protect yourself from air pollution.

In summary

Air quality is the amount of air pollution present in the air. Air pollution is a mixture of substances, including dust, dirt, soot, smoke and liquid droplets. The main sources of air pollution are transport, energy production and industry. Air quality can be measured by observing different factors which can be divided into two groups – particles or gases.
