| Total mercury (Hg) concentrations and lipid composition data, including fatty acid profiles, for 61 midtrophic species (fish, cephalopods, crustaceans) collected from continental slope waters off south-east Australia were examined. Overall, Hg concentrations were greatest in fish (0.01-0.30 mu g g(-1) ww) (with highest content found in barracouta (Thyrsites atun) and whiptails (Coelorinchus fasciatus)), compared with cephalopods (0.01 and 0.17 mu g g(-1) ww) and crustaceans (<0.04 mu g g(-1) ww). Lipid composition varied between species and within habitat (mesopelagic, bathypelagic and benthic). Mean total lipid content ranged from 0.5 to 13.2% ww, and in most species was dominated by triacylglycerols and phospholipids. In fish and squid, fatty acids... |
