الوصف
Pollution is very broad term that has many different meanings; however, it can be
considered as anthropogenic concept which results from human activities (Mason
2003). On the other hand, similar effects can result from natural environmental
changes, such as biogeochemical cycling of elements or ecosystem processes.
There is a broad definition quoted by Holdgate (1979) explaining pollution as “The
introduction by man into the environment of substances or energy liable to cause
hazards to human health, harm to living resources and ecological systems, damage
to structure or amenity, or interference with legitimate uses of the environment''. Thus,
pollution is defined on the basis on anthropogenic-induced introduction of substances
or energy.
