THE INFLUENCE OF ENVIRONMENT PROCESSES ON HEALTH

1.    Freon and the Ozone Layer

Freon is the general name, and chemical name is Fluoric-carbon (chemical materials bonding Fluoride and carbon), among which CFC (Chloro-fluoric Carbon: designated Freon) and HCFC (Hydro Chloro-fluoric carbon: designated Freon) destroy Ozone layer in space. "Specially designated Freon" contains chlorine.

HFC (HydroFluoric Carbon) is called Alternative Freon in general, which does not destroy Ozone layer in space due to no chlorine involved.

Since Ozone gas is unstable material, which is easily decomposed by absorbing solar energy. However, soon after being decomposed, the fluorine atom recombines with oxygen again and returns to Ozone to make balance as nature. In case Freon contains the chlorine atoms, the chlorine separated from Freon by ultraviolet light makes chemical bonding with Ozone. Then, Ozone cannot return to original Ozone soon, which results in Ozone-destroy and generates Ozone-hole in space.

2.   Air Pollution

Air pollution is the introduction of particulates, biological molecules, or other harmful materials into the Earth's atmosphere, possibly causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment.

3.   The Effect to Reduce Air Pollution

a.    To reduce logging

b.   To do industrial management

c.    To reduce the usage of motor vehicles

d.   To reduce the use of products that contain CFC, such as spray paint, hair spray, air conditioners, and choosing non-CFC products.

e.   To produce the use of lead in gasoline

f.    Tho produce environmentally friendly cars, i.e. the cars that use gas-fueled

g.   To install a catalytic converter on the car’s muffler
