2. Pollution along the coast is usualy due to both farming and urban, industrial activity

3. Most urban and industrial dumping is legally in order (each pollutant keeping within the bounds). However, not always are the size and frequency of dumping in the same area taken into account.

4. Group 4 has gathered information about the quality of sea water along our coast focusing the attention on a research on shellfish which prove to be particularly suitable to be used as chemical, microbiological and toxicological pollution indicators; being filter-feeders, they draw nourishment from filtering water which enables them to stockpile large quantity of chemicals, bacteria, viruses, algal cells and/or toxic principles inside their digestive tissue.

6. The results of this research reveal that ...

7. chemical parameters keep within the legal bounds on most part of the coastline, while microbiological analyses point out the presence of coliform in some more densely populated areas. Only Cumae coastline (north of Naples) appears to be heavily influenced by a big purification plant dumping which prevents shellfish from living.

8. Marine fauna in the Gulf of Naples is the same as in the Tyrrhenian sea

9. It is very rich in the so-called “Blue fishes”

10. Besides “blue fishes” there is a large variety of different species like:

11. Sardina Sardina pilchardus

12. Alice (o Acciuga) Engraulis encrasicholus

13. Sgombro Scomber scombrus

14. Aguglia Belone Belone

16. Spigola dicentrarchus lobrax

17. crustacea

22. Cephalopoda molluscs

32. Nudibranchi Ipselodoris valencenniens Nudibranchi may be found on the rock walls

34. and gaudy gorgonias Gorgonie Paramuricea clavata
