The Factors That Affect Climate Change

There are many factors that have a large impact on climate change, but the one we decided to address is air quality and air pollution. Air pollution is one of the few types of pollution. This one specifically refers to pollution in a sense of the contamination of the air by smoke and harmful gasses. There are two main types of air quality, indoor and outdoor. The main factors that affect air quality are as follows:

The main factors affecting outdoor air quality:

Topography - Concentrations of pollutants can be greater in valleys than for areas of higher ground. This is because, under certain weather conditions, pollutants can become trapped in low lying areas such as valleys. This happens for example,

Too low humidity causes eye irritation, dry skin, and rashes, whereas too high humidity results in water damage and mould problems and favours the growth of dust mites.

The main factors that affect INDOOR air quality are as follows:

Chemicals - Two common causes of complaint regarding poor indoor air quality are bad smells and irritation of the eyes, nose and throat. Such irritation may be induced by specific chemicals, but also by factors such as dry air. Bad smells are not harmful in themselves but may cause unpleasant effects and increase symptoms such as headache, nausea, and irritation of eyes or throat. The hazards associated with chemicals and their effects on health are not always well known, particularly for long term exposures.

Temperature - As well as causing discomfort, indoor air that is very cold or hot is highly unhealthy. Air that is too warm, for example, aggravates the effects of insufficient humidity.

Ventilation - It is one of the most important factors determining indoor air quality. Poorly aired offices and schools, for instance can affect health and work or academic performance. Controlled ventilation is especially needed in heavily insulated buildings that allow little air exchange with the

This is for instance a problem in damp buildings or indoor environments where there is mould because many fungi release substances that cause allergies. Virus infections may also be transmitted by indoor air and some of them can lead to an increase in asthma and allergies.

Suspended particles - Coarse, fine and ultrafine particles in the surrounding air are known to cause adverse health effects, including on the respiratory and cardiovascular systems. Particles may in part come from outdoor pollution, but can also form indoors by the burning of fuels for heating and cooking, and by reactions between ozone and some volatile organic compounds (VOCs). In addition, man-made nanoparticles, that are increasingly used in consumer products, may have an impact as indoor air pollutants.

Radon - Radon is a gas that occurs naturally in soil and rock in some regions and that can get inside buildings by diffusing through the soil. In indoor air, it can lead to lung
