Preventing air pollution
Causes and effects of air pollution
There are two main types of air pollution:
- fumes - which can include vapours, gases, smoke and odours
- dust - dry particles
These can be produced in a number of different ways. Manufacturing processes, particularly those that use chemicals and machinery, can cause air pollution. Less obviously 'dirty' processes, such as cleaning and packaging goods, can also produce harmful emissions.
Businesses particularly at risk of causing air pollution
Most types of business can cause some form of air pollution if they are not run properly. Some businesses are particularly at risk of creating air pollution, including:
- construction, building and demolition trades
- vehicle repairers
- mines and quarries
- hauliers and other transport businesses
- waste management businesses
- dry cleaners
Sources of air pollution from business premises include:
- emissions from burning fuels in furnaces and boilers
- burning material in the open
- dust and fumes from poor waste storage and ventilation systems
- ozone (an air pollutant which can be harmful to human health) from office equipment such as copiers and laser printers
- exhaust fumes and dust from distribution and delivery vehicles
Effects of air pollution on the environment and human health
Air pollution impacts seriously on the environment in a number of ways. Emissions of greenhouse gases contribute to climate change and ozone-depleting substances cause damage to the ozone layer. This type of pollution also increases the acidity of rain, which causes damage to buildings, land, fresh water and sea water, wildlife and plants.
There are many associated risks to human health from air pollution. Those who are exposed to poor air quality can face an increased risk of developing or exacerbating a range of illnesses including lung and breathing problems, skin conditions, cancer and organ damage.
