About 120 large cities are located along the coasts of the Mediterranean Sea, which is shared by several countries from three different continents. All these coastal cities discard untreated or partially treated wastewater into the Mediterranean basin. Furthermore, the lack of public awareness and the often misleading communication on environmental issues, encourage the inhabitants of these cities to continue using the Mediterranean Sea as a dumping place for sewage.
Due to the fast growing populations of Mediterranean coastal cities and the industrial and agricultural development, large quantities of biological (i.e. viruses, bacteria, and other parasites) and chemical contaminants (i.e. pesticides, detergents, hydrocarbons and other toxic materials) are released into the sea.
All these contaminants represent a great threat to the marine ecosystems; severe infectious diseases like cholera, typhoid, paratyphoid and some other endemic diseases have already been reported in many localities.
Therefore, disposal of untreated wastewater in the Mediterranean Sea should be stopped promptly or at least reduced. A joint monitoring strategy between the Mediterranean countries should be developed and implemented to face and control these problems.
