When a cars or any vehicle is running the substance like carbon monoxide,
hydrocarbon particles, soot, nitrous oxide, trace amount of halogens trace
amount of heavy metals and some other volatile organic compound released in to
the atmosphere. The release of this kind of harmful is based on type of
gasoline that are using for the vehicles. In 1970’s people were using lead gasoline
which is more dangerous than what we are using now. But still burning of this fossil fuel is
increased day by day. The usage of vehicle was tripled when compared with
vehicle usage in 1970’s. I think because
of traffic also there is more consumption of fossil fuels because in traffic we
stay one hour without turning off the engine .Not only the gasoline but also the
fluid used for maintenance of vehicle like antifreeze, brake fluids, motor oil,
transmission hydraulic fluids, windshield –wiper fluids, air conditioner
refrigerator’s..etc.,
Most of vehicles
manufactured before 1994 use CFC-12 coolant which is very toxic and cause
depletion of the ozone layer that’s why CFC-12 is banned in US and are using
alternate coolant instead of CFC-12 which has no effect on ozone layer. Even
some developed and developing countries are using bio gasoline to reduce the
atmospheric pollution.
I
think not only usage of bio fuels but also, the government should pass a rule
to stop using vehicle a day in a week in any cost except for medical emergency.
It is not possible to implement such kind of rule except there is awareness in
people.
As also better to take public transport instead
of taking private transport.
