Abstract:
What is the pollution? We can define the pollution as an undesirable change in physical, chemical and biological properties of the climate or the earth. These changes endanger health, survival and activities of the human beings and the creatures. The chemical substances resulting from industrial complexes or domestic sewages can enter the seawater and they may be harmful to the human being and creatures living around. Kinds of pollution We can recognize two kinds of pollutants biologically: declinable and staying.(permanent and temporary) Declinable pollutants can be decreased during natural processes through engineering methods like the refinement of sewage water as long as the system is not polluted completely. Declinable pollutants that enter the seawater like human sewage, animal and agricultural additional can be disintegrated quickly. The permanent pollutants are not disintegrated naturally including heavy metals like lead, mercury, cadmium, Nickel and metals like Aluminum and their entering into seawater should be prevented. In present study, we consider the rate of heavy metals in Persian Gulf.
