| biomagnification of mercury through a subtropical coastal food web off southwest florida. | total mercury and stable isotopes of nitrogen (δ(15) n) were measured in samples from 57 species of invertebrates (17 species) and finfish (40 species) from the coastal waters off southwest florida, usa, to evaluate the biomagnification of mercury through the food web. mercury concentrations (wet wt) and δ(15) n values were highly variable among species, ranging from 0.004 mg/kg in an unidentified species of brittlestar (class ophiuroidea) to 2.839 ± 1.39 mg/kg in king mackerel (scomberomorus ca ... | 2014 | 24123350 |
| consistently low mercury concentrations in dolphinfish, coryphaena hippurus, an oceanic pelagic predator. | compared to total mercury concentrations in other oceanic pelagic and syntopic fish species examined from waters of the southeastern united states (e.g., king mackerel, scomberomorus cavalla; wahoo, acanthocybium solanderi; yellowfin tuna, thunnus albacares; blackfin tuna, t. atlanticus), total mercury concentrations in dolphinfish, coryphaena hippurus, examined were consistently low. dorsal-muscle tissue from 385 dolphinfish (317-1395 mm fork length) from florida offshore waters was analyzed fo ... | 2009 | 19539279 |
