Level and fate of trace metals in the lagoon of Venice (Italy)
TLDR
In this paper, the first results of dissolved (total concentration and hydrophobic fraction) and particulate trace metals (core sediment and suspended matter) in the lagoon of Venice were presented.About:

Significance of colloids in the biogeochemical cycling of organic carbon and trace metals in the Venice Lagoon (Italy)
TL;DR: In this article, a cross-flow ultrafiltration device was used to separate colloidal organic C and trace metals from the waters of a highly productive coastal environment (the Venice Lagoon, Italy).
Journal ArticleDOI
Twentieth century overview of heavy metals in the Galician Rias (NW Iberian Peninsula)
TL;DR: There is an urgent need to standardize procedures, employ 'clean' procedures to avoid contamination of samples and regular assessment of analytical accuracy with CRMs in order that results can be compared among the scientific community and produce reliable results.

Benthic macrofauna changes in areas of Venice lagoon populated by seagrasses or seaweeds.
TL;DR: Seagrass stations exhibit a better oxidisation of the environment and show conditions more favourable for macrofauna colonisation, especially in the presence of macrophytes which are characterised by very well developed below-ground systems such as Cymodocea nodosa.

Concentration and fate of trace metals in Mekong River delta.
R.M. Cenci,J.-M. Martin +1 more
TL;DR: The evolution of the DP trace metal concentration in the surface water within the salinity gradient suggests no noticeable exchange between the particulate and dissolved phase, which is in good agreement with those observed in most plume structures studied so far.
Journal ArticleDOI
Lead-210 as a tracer of atmospheric input of heavy metals in the northern Venice Lagoon
TL;DR: A chronology for the accumulation of a salt marsh core taken in the Venice Lagoon has been obtained from the activity-depth profile of excess 210 Pb, a naturally occurring radionuclide supplied to the marsh from the atmosphere.

Elemental mass-balance of material carried by major world rivers
Jean-Marie Martin,Michel Meybeck +1 more
TL;DR: In this paper, an estimate of average river particulate matter (RPM) composition was based on analyses of more than 40 elements in the Amazon, Congo, Ganges, Magdalena, Mekong, Parana and Orinoco rivers, covering the whole spectrum of morphoclimatic features.
Journal ArticleDOI
Interactive influences of bioactive trace metals on biological production in oceanic waters
TL;DR: In this paper, the authors present an overview of the oceanic chemistries of the bioactive trace metals, Mn, Fe, Co, Ni, Cu, and Zn, combining field data with results from laboratory phytoplankton culture-trace metal studies and speculate on the potential influences of these trace metals on oceanic plankton production and species composition.

Transport phases of transition metals in the Amazon and Yukon Rivers
TL;DR: In this article, samples representing yearly averages of material transported by the Amazon and Yukon Rivers were analyzed to separate the transition metals (Cr, Mn, Fe, Co, Ni, and Cu) into the following transport phases: (1) crystalline particles, (2) metal hydroxide coatings, (3) solid organic material, (4) sorbed material, and (5) those in solution.

Complexation of zinc by natural organic ligands in the central North Pacific
TL;DR: In this paper, the complexation of Cd by natural organic ligands in the upper 600 m of the central North Pacific was determined with differential pulse anodic stripping voltametry at a thin mercury film, rotating glassy-carbon disk electrode.

Copper sensitivity of Gonyaulax tamarensis 1
TL;DR: The copper sensitivity of the dinoflagellate Gonyaulax tamarensis was examined in artificial seawater medium as mentioned in this paper, and the chelators tris(hydroxymethylamino)methane (Tris) and ethylenedinitrilotetraacetic acid (EDTA) were used to demonstrate that copper toxicity is a unique function of cupric ion activity.
