| mercury (hg) speciation in coral reef systems of remote oceania: implications for the artisanal fisheries of tutuila, samoa islands. | we investigated hg in muscle tissue of fish species from three trophic levels on fringing reefs of tutuila (14°s, 171°w), plus water, sediment and turf alga. accumulation of total hg in the herbivore acanthurus lineatus (acanthuridae, lined surgeonfish, (n=40)) was negligible at 1.05 (±0.04) ng g(-1) wet-weight, (∼65% occurring as methyl hg). the mid-level carnivore parupeneus spp. (mullidae, goatfishes (n=10)) had total hg 29.8 (±4.5) ng g(-1) wet-weight (∼99% as methyl hg). neither a. lineatus ... | 2015 | 26028166 |
