Variations in concentrations of dissolved sugars were studied along the salinity gradient of a smallestuary (Elorn, Bay of Brest, France) from February 1985 to January 1986. Total dissolved carbohydrate(TDCHO) and dissolved monosaccharides (MCHO) were measured by the methods of Burneyand Sieburth and Johnson and Sieburth respectively. It must be noted that these methods cannotdistinguish between carbohydrates and carbohydrate-like substances; consequently, these methodsprobably do not closely...

210-Pb activity is an useful technique in environmental investigation, todetermine sediments accumulation rates, geochronology, and to study metals.Its activity decline exponentially with depth, and is inversely proportional to thesedimentation rate at non-impacted ecosystem. Dating of sediments, combinedwith chemical profile, allow the study of the impact events in coastal zones.In the present study, we have investigated the history of metals concentrationsand sedimentation rates of recent s...

The hydrochemical, physical-chemical, and biological dynamics were studied in the eastern waters of the gulf ofCariaco, where wind and precipitation patterns govern these processes to a significant degree. Average monthly values forboth surface and bottom waters were respectively as follows: temperature: 25.69 °C each; salinity: 35.41 and 35.75 units;density anomaly (ó-t): 23.43 and 23.84 kg/m3; oxygen concentration: 184.49 and 178.38 mmol/kg; pH: 7.98 and 7.94;nitrates: 3.18 and 4...

The content of Fe, Mn, Cu, Cr, Ni, Zn, Cd and Pb in muscle tissuesof fish and crustaceans from the Unare lagoon (Lagunade Unare) in the state of Anzoátegui, Venezuela, was analyzedby flame Atomic Absorption Spectrometry. The levels of thesemetals present in suspended material of the water and in sedimentswere also determined in order to detect possible impacton the ecosystem. The mean concentrations in the water werelow (0.104-0.53 μmol/L Fe; 0.004-0.06 μmol/L Mn; 0.002-0.028μ...
