Polyvinyl chloride
or commonly called PVC is the third most widely produced plastic. PVC is mostly
used in construction now. It can be used as water pipes, sewage pipes, or used
on the coating of electrical wires. There are other uses for PVC such as sports
and clothing. PVC seems to be a great product, but it has problems. The
problems with PVC come from how it is made and what toxics the process gives
off.
The process of
making PVC is very hazardous to the workers and the environment. PVC gives off
dioxin. Dioxin is the worst carcinogen in the world today. Once this carcinogen
gets into the body, it can cause cancer and many other health problems. The
environment also takes a hit from dioxin. The carbon dioxide given off during
this process goes into the atmosphere with dioxin in it. The toxic air is then
carried up to the North Pole by the wind. Once in the North Pole, animals eat
plants that have it on their leaves or in there stems. The dioxin stores inside
the animals fat and never leaves the body. This animal then gets eaten by
another animal in the life cycle. The life cycle keeps going and more and more
animals get affected. For example, polar bears have extremely high levels of
dioxin in them according to Mary Jane Derex. She told use that in recent years
polar bears have been increasing steadily in dioxin levels that would kill
humans. The cubs of polar bears are being born with these extremely high
levels. This is part of the reason why the polar bear population is becoming
extinct.
Dioxin also does
not break down rapidly. It stays in the environment or in animals for a very
long time. This will cause problems in the food chain for decades. It will also
cause problems for humans; too. If we get really high levels of dioxin in our
bodies it will kill us. The only safe way to rid the environment of dioxin is
to stop making PVC. Is this really an option?
PVC has
revolutionized the construction business. It is cheaper and more flexible than
copper or other metals that are primarily used for piping. There are many
advantages that PVC gives to construction companies. This is why PVC is still
being made today. The only way to make this process stop is have a government
mandate. This probably will not happen, but it should to safe the environment.
