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

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.

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.

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.
