Quality air helps us to breathe and make us healthy, which is made up largely of nitrogen and oxygen, together with small quantities of several other non-toxic gasses such as helium. Any potentially harmful substance, be it another gas or a cloud of particles, which contaminates the atmosphere, is regarded as air pollution.
What Is The Quality Air Pollution?
Natural phenomena like forest fires and volcanoes pollute the air with smoke and sulfur. But most global air pollution is human-made. Fossil fuels burnt to generate electricity, the industrial manufacture of metals and chemicals and the use of road vehicles all create a cocktail of pollutants which affects the quality air, which we breathe.
What Causes Pollution In The Quality Air?
Why Not Controlling Vehicles Engine Exhaust For Quality Air Pollution?
A conventional petrol engine gives off carbon monoxide, carbon dioxide, nitrogen oxide, sulfur dioxide, lead particles, and hydrocarbons. Lead pollution, in particular, is known to cause various physical and mental disorders, especially in children. Since the introduction of lead-free petrol in 1986, airborne lead levels have fallen by 70% and lead emission from cars reduced from 6,500 tons to 2,200 tons per year.
But emissions of hydrocarbons and nitrogen oxides produced by city traffic are increasing. Not only noxious in themselves, when acted on by sunlight they produce a photochemical smog which can contain up to ten times the normal concentration of low-level ozone. However, harmful emissions can be substantially reduced by the use of catalytic converters. Since January 1993, all new cars in the UK and EC have been legally required to have one fitted.
Severe Quality Air Pollution Leads To Death Also
Severely quality air pollution can cause death, but in most Cases, the pollutants we breathe are fairly dilute and their effects either slight or cumulative. Sore eyes and throat may be experienced by city dwellers — particularly on hot summer days. The long-term effects of breathing highly polluted air may include the development of bronchitis, emphysema, heart disease and cancer. However, there is no evidence to show that inhabitants of heavily polluted areas were particularly prone to illness.
Quality Air Pollution:
Its source and potential effects
|Carbon Monoxide||Power stations, car, exhausts||Heart disease|
|CFCs||Aerosols. refrigeration units||Heart, lung, nervous system damage|
|Formaldehyde||Adhesives, car exhausts||Eye, lung damage, cancer|
|Hydrocarbons||Car exhausts||Produces ozone|
|Hydrogen sulphide||Refineries, sewage||Nausea, and vomiting|
|Lead||Metal manufacture, car exhausts||Brain, nerve and blood cell damage|
|Nitrogen oxides||Power stations, car, exhausts||Lung disorders, ozone formation|
|Ozone||Sunlight on nitrogen oxides||Eye, lung damage|
|Sulfur dioxide||Power stations, steelworks||Eye, lung damage|
How Is Quality Air Pollution Controlled?
In Most of the advanced countries, the Department of the Environment is responsible for quality air. And they Inspectorate of Pollution controls emissions from major industries; local authorities control emissions to air from smaller processes. These organizations have the power to fine or even shut down offending companies.
Is Pollution In The Quality Air Dangerous?
The London smogs of the 1950s claimed the lives of thousands who were vulnerable due to existing cardio-respiratory conditions. This pollution was caused by domestic coal burning and was significantly reduced by the 1956 Clean Air Act, which created ‘smokeless zones.’
The effects of quality air pollution may not be so apparent today but are potentially still deadly. Cities and industrial sites remain the most heavily polluted, but the pollutants are free to disperse elsewhere.
How To Control Quality Air Pollution On The Road?
- Keep your car journeys to a minimum. Walk, cycle, use public transport, or share your car, and combine errands in one trip.
- Ensure your vehicle is properly serviced and maintained. Keep it garaged or under cover (a cold engine emits far more pollution than a warm one) and avoided using the car for short journeys, especially when cold.
- Do not let the motor idle. In a traffic jam, switch off if.
- likely to be delayed for more than a few minutes.
- Try to avoid sudden braking or rapid acceleration, and do not speed.
How To Control Quality Air Pollution In The Home?
Turn down the central heating. Ensure boilers are regularly serviced. Use smokeless fuel or install a smokeless appliance.
Limit your use of household cleaners, polishes, etc.
How To Control Quality Air Pollution In The Garden?
Shred and compost yard waste, rather than light a bonfire, and never burn household waste.
