Interesting Air Quality Facts
In December 1952, London had a very bad 'smog' that lasted 5 days!
Ozone gas (O3) is formed when nitrogen oxides react with sunlight.
Stratospheric Ozone, which is 10 to 15 miles above the earth's
surface, is essential to life because it filters harmful ultraviolet
radiation from the sun, reducing the amount reaching the earth's
surface.
In cities where it is very sunny and very polluted,
photochemical smog can get so bad; children are
sometimes kept away from school!
Plants and trees use up carbon dioxide and therefore
help to 'clean' the air.
Lichens can provide a simple and effective way of
establishing the degree of pollution in a given area
VOC's stand for Volatile Organic Compounds and are air pollutants
that evaporate easily.
As long ago as 1273, coal was first banned in London, because it
could be bad for your health.
The word 'Bonfire' comes from the medieval term 'bone fire' - when
animal bones were burnt in the street.
In one year, a car an produce 4 times its own weight in carbon
monoxide
Air Quality is now measured at over 25 locations in the Chiltern
District.
Children are particularly vulnerable to air pollution - they breathe faster
than adults and inhale more air per pound of body weight
People travelling by car can be exposed to higher levels of pollution
than pedestrians or cyclists
Cycling can reduce the risk of heart disease, reduce stress and
increase life expectancy
During term time, 20% of traffic in rush hour is related to children
being driven to school
There are more than 26 million vehicles licensed to use UK roads.
It would take 20 of today's new cars to generate the same amount of
air pollution as one mid-1960s model car
Service delivery vehicles spend 20-60% of their time idling, which
costs fleet owners a lot of money and gets them nowhere.
Added weight makes your car's engine run less efficiently, increasing
air pollution
The sun is estimated to be 4.6 billion years old and 150 million km (on
average) away from Earth.
Starting a car cold increases trip emissions compared to starting the
car warm.
For a 5-mile trip, starting the car cold generates about 30 percent
more nitrogen oxide and 60 percent more carbon monoxide than
starting the car when it is warm
Scientists predict that around the world, average temperatures could
increase by anywhere from 1.4 to 5.8 degrees Celsius over the next
100 years. To understand what this means think about the fact that
today's average global temperatures are only about 5 degrees warmer
than they were during the last Ice Age about 18,000 to 20,000 years
ago
Greenhouse gases are an important part of the Earth's atmosphere.
They help warm the Earth, without them the Earth's average
temperature would be -18 degrees Celsius! The problem is that the
burning of fossil fuels creates more greenhouse gases than the planet
needs.
