| 1 | Influence of dissolved organic matter character on mercury incorporation by planktonic organisms: An experimental study using oligotrophic water from Patagonian lakes显示文摘Ligands present in dissolved organic matter(DOM) form complexes with inorganic divalent mercury(Hg2+) afecting its bioavailability in pelagic food webs. This investigation addresses the influence of a natural gradient of DOM present in Patagonian lakes on the bioaccumulation of Hg2+(the prevailing mercury species in the water column of these lakes) by the algae Cryptomonas erosa and the zooplankters Brachionus calyciflorus and Boeckella antiqua. Hg2+accumulation was studied through laboratory experiments using natural water of four oligotrophic Patagonian lakes amended with197Hg2+. The bioavailability of Hg2+was afected by the concentration and character of DOM. The entrance of Hg2+into pelagic food webs occurs mostly through passive and active accumulation. The incorporation of Hg2+by Cryptomonas, up to 27% of the Hg2+amended, was found to be rapid and dominated by passive adsorption,and was greatest when low molecular weight compounds with protein-like or small phenolic signatures prevailed in the DOM.Conversely, high molecular weight compounds with a humic or fulvic signature kept Hg2+in the dissolved phase, resulting in the lowest Hg2+accumulation in this algae. In Brachionus and Boeckella the direct incorporation of Hg from the aqueous phase was up to3% of the Hg2+amended. The dietary incorporation of Hg2+by Boeckella exceeded the direct absorption of this metal in natural water,and was remarkably similar to the Hg2+adsorbed in their prey. Overall, DOM concentration and character afected the adsorption of Hg2+by algae through competitive binding, while the incorporation of Hg2+into the zooplankton was dominated by trophic or dietary transfer. | María C.Diéguez Claudia P.Queimalios Sergio Ribeiro Guevara Mark Marvin-DiPasquale Carolina Soto Crdenas María A.Arribre | 2013 | Journal of Environmental Sciences2013，25，10： | 6 |
