“…The high phytoplankton densities recorded during the summer of 1983 in surface waters of the inner Gulf of Naples were similar or higher than those usually reported for other eutrophic areas of the Mediterranean Sea (BENON et al, 1977;PUCHER-PETKOVI~ & MARASOVIC, 1980;IGNATIADES, 1984). This is hardly surprising because the dense urban settlements and high industrialization here result in constant nutrient enrichment (CARRADA et al, 1980).…”

“…Two examples are the River Nile, whose effect on southeastern Mediterranean waters was restored ZINCONE, MONTRESOK 6t MARINO following the filling of the Aswan reservoir (DOWIDAR, 1984), and the Po River in the northern Adriatic Sea (REVELANTE & GILMARTIN, 1976GILMARTIN, a, 1976 b; GILMAR-T I N & REVELANTE, 1980). In other cases, such as the Gulf of Fos, which receives waters from the Rhone and Durance rivers, salinity-tolerant species sometimes constitute the bulk of the phytoplankton population (BLANC et ul., 1975;BENON et al, 1977).…”

Thirtccn sampling cruiscs were conducted at wcckly intervals in the inncr part of thc Gulf of Naplcs in the summcr of 1983 to invcstigatc the effects of cxccss nutrient inputs on phytoplankton communitics. High surface phytoplankton conccntrations (up to t. 15 X lox cells. I-[) wcrc rccordcd, particularly near Naplcs harhour and along the castcrn coast, two locations that rcceivc most of the area's scwagc and industrial dischargc. Phytoplankton populations wcrc gcnerally dominatcd by small spccics. mainly diatoms, which wcrc associatcd with small phytotlagcllatcs. Spccics divcrsity valucs wcrc rclativcly high (H' S 3.62) in most samples. Throughout the sampling period a high spatial and temporal variability for phytoplankton abuntlances and spccics composition was ohserved.

“…This kind of industrial pollution has already been highlighted in previous studies (Benon et al, 1977a(Benon et al, , 1978 and seems to be closely connected with the flow of the RhGne river, especially during the cold season. A more detailed study of metals in the benthic and planktonic organisms seems desirable in order to try to evaluate the impact of this pollution on the marine populations of this neritic sector.…”

Surrounded by a heavily industrialized area, subject to natural fresh water dilution (Etang de Berre, Rhone river), the Gulf of Fos is an unbalanced neritic zone. Its distrophic character is accentuated by numerous continental discharges; furthermore, the climatic instability which characterizes this region(irregular periods of winds, fluvial risings) reinforces the changing ecological conditions in the gulf waters. The present paper shows the major ecological conditions in that neritic area, and the main events occurred during the 1976-1978 period, through and extensive sampling network. The principal regulating features are thus described by the mean of a mathematical data processing (Principal Components Analysis).

Moreover, algal tests are irsed for rcprc~senting the troplric. sit,uation and for det,errniniirg the limit.ing nutrient, hiit, also for det~ei~inining the toxic influencing of biocenosis by hydrocarbons, too.

Indiscrinunnte abuse of water as a rcwilt of the increase in the hunian population and the growth of industries has been continiiously contributing t o the qualitative deterioration of our inland waters. The sea is the ultiiiiate sink for waterborne pollutants arid duc to its large inass of water it lessens the severity of pollution by dih~l1oi1.

However, if we continue to discharge inore and inore pollutants into the sea, the day inny not be far off when the sea water Loiiiposition will c h i a t e from its present averages. Keeping in view the alarming water pollution problems, considerable attention has been given during the past several years to visualize and define its consirquences, with particular cniphasis on surreillance and monit ormg aspects.=\ fcw decades ago even in developed countries it had been a coniiiioii practice t o einploy only cheinical criteria in water pollution studies, thus coiiipletely ignoring the biological inforinatiop which is certainly of much use while interpreting the sigiiificance of the physico-chemical observations (HYNES). The importance of utilizing hiological information t o supplement chemical findings for a better evaluation of ~)ollutional conditions has been established only in recent years.Algae are prevalent in all water bodies including ponds, reservoirs, lakes, streanis, rivers and oceans.
