1. Water pollution General characteristics of the Mediterranean Sea The water pollution of the Campania region What is sea pollution? The causes of pollution of the marine environment Ways to fight sea pollution The purifiers and how they work

2. The Mediterranean is a sea between Europe, Asia and Africa, connected to the Atlantic Ocean through the Strait of Gibraltar, the Dardanelles, the Sea of ​​ Marmara and the Bosphorus, linking the Black Sea, another inland sea between Europe and Asia. Its approximate area is 2.51 million square kilometers and has a maximum development along the parallels of about 3700 km. The total length of its coastline is 46,000 km.

3. Water pollution is the contamination of marine waters, inland surface waters (rivers and lakes) and groundwater. Even groundwater may in fact be subject to contaminants, although they are protected by the overlying strata, which can be more or less impermeable. The water pollution can have different causes that lead to the inevitable and in many cases compromising alteration.

4. The causes of marine pollution The main causes of pollution of the seas and oceans can be: 1) Pollutants from human activities, from the urban sewage, organic products of agricultural origin such as pesticides and fertilizers, pollution of industrial waste; 2) Petroleum released by oil tankers or oil platforms by accident, or unfair practices; 3) Radioactive products released during nuclear testing., 4)Overheating of coastal waters.

5. The causes of the pollution of the seas (Part 2) 6) Urban sprawl on the coasts and seaside tourism, in the form of uncontrolled mass phenomenon; 7) The landfill of plastic and other non-degradable solid waste. 5) Over-exploitation of fish resources which involves the depletion of fish population and, in some cases, the risk of extinction;

6. Of 20 sample points, 14 were "outside the law" including 12 "heavily polluted." The sea around Naples and Campania is partially polluted. Analysis by Green Schooner Legambiente has reported the following results: The Caserta area in 65% of facilities was unsatisfactory. Not better is the status the purification plants in the province of Naples, where he controls the six large regional plants revealed that 44% is not satisfactory.. In the province of Salerno there are over 200 sewage treatment plants, and out of 100 controls, the half was 'not in conformity'

7. The simple action of monitoring of marine waters is not enough, so to resolve in part the 'pollution there are different methods: Kind of pollutionsolutions Urban waste : Industrial discharges : Toxic and harmful substances : Oil released by oil tankers after accidents: Overcrowding of the coasts : Recycling, Waste collection, Temporary closing of bathing zones Purifiers Tighter and more accurate control by the the maritime police and more severe laws More attention and correct maintenance Prohibitions on building in particular areas

8. Wastewater treatment process of removing contaminants from wastewater of urban or industrial origin, that is of an effluent which has been contaminated by organic pollutants and / or inorganic. The wastewater cannot re-enter into the environment as if the contact ends in the ground, the sea, rivers and lakes will not be able to receive an extra amount of pollutants. The purification treatment of urban sewage consists in a succession of stages of physical, chemical and biological from the wastewaters the unwanted substances, which are concentrated in the form of sludges are removed
