“…In this regard, both the rate of protein synthesis and the potential for cellular biosynthesis have been shown to be much more closely correlated with changes in ECA values than with fluctuations in the absolute concentrations of intracellular ATP, ADP, or AMP (311). The potential applications of ECA measurements in experimental microbial ecology have been discussed by several investigators (28,68,148,180,333,338).…”

“…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).

“…The mean level measured for Pb (0.050 ± 0.033 mg/kg) in the different sampling sites ranged from 0.017 ± 0.003 mg/kg in Port Cros and Canari to 0.107 ± 0.006 mg/kg in Couronne. This site is located in the industrial zone of the Gulf of Fos, hosting the most important commercial harbor in the Mediterranean, which is also one of the most contaminated areas of the French Mediterranean coast, in particular by Pb (Benon et al 1978). These results are in good In the 39 analyzed samples, Pb levels were below the maximum value of 1.50 mg/kg (ww) set out in the Regulation (CE) 1881/2006 for bivalve mollusks.…”

Levels of 14 trace elements (Al, Ti, V, Cr, Mn, Co, Ni, Zn, As, Se, Cd, Sn, Hg and Pb) and 5 arsenic species (arsenite/As(III), arsenate/As(V), monomethylarsonic acid/MA, dimethylarsinic acid/DMA and arsenobetaine/AsB) were assessed in the gonads of sea urchin samples (Paracentrotus lividus) from North-West Mediterranean Sea (French coast). The samples were collected from 13 sites characterized by different types and levels of chemical contamination. Trace elements levels were measured by inductively coupled plasma-mass spectrometry (ICP-MS) following microwave (acid) digestion in a closed system, whereas As speciation analysis was carried out by ion-exchange liquid chromatography coupled with ICP-MS after microwave assisted extraction. High levels of trace elements were found in sea urchins sampled from Corsica whereas the samples from Théoule were found to be the least contaminated. From all the analyzed urchin samples, none showed Cd, Hg or Pb concentrations above the regulatory levels set by the European Community (EC) No. 1881/2006 for seafood or bivalve mollusks. Regardin arsenic specation, AsB was con rmed to be the predominant species. Inorganic As (As(III) + As(V)) was mainly constituted by As(III), which was quanti ed in all samples. Methylated As forms (MA and DMA) represent 9 to 23% of the total As.
