A preliminary study on metal and nutrient concentrations in running water systems in southern New Caledonia Migon, C. Motegi, C. /Mari, Xavier Dufour, A. Weinbauer, M. Running waters Metals Nutrients New Caledonia Metal and nutrient concentrations were measured in five running water sampling sites of New Caledonia. Metal concentrations were homogeneous (Ni; 22.7-50.6 mu g L-1) or not (Fe; 37-749 mu g L-1). Concentrations of Ni, Cr, Fe were high, including high dissolved fractions (up to 47.8, 70.8 and 417 mu g L-1, respectively). Concentrations of anthropogenic metals (Ag, As, Cd, Cu, Pb, Sb, V, Zn) were low (maximum: total Cu, 0.6 mu g L-1). The contamination of waters is presumably due to soil weathering and mining activities. Metal concentrations and phosphate depletion (<0.04 mu mol L-1) suggest constrained conditions for the development of aquatic life. 2011 text https://www.documentation.ird.fr/hor/fdi:010054217 fdi:010054217 Migon C., Motegi C., Mari Xavier, Dufour A., Weinbauer M..
