Vanadium. Kelp bass and kelp rockfish did not exhibit significant HabType*TL interactions for vanadium (data not shown). Vanadium concentrations in kelp bass were also not significantly associated with TL (data not shown) and between HabTypes (Figure 28). Vanadium concentrations in kelp rockfish were inversely associated with TL (F 1, 56.1 =38.93, P
ference was detected in kelp rockfish (Figure 30). In general, kelp rockfish exhibited lower concentrations of zinc at oil platforms (mean, 53. µg Zn/g; 95% confidence interval, 49.-59. µg/g) than at natural areas (mean, 68.µg Zn/g (95% confidence interval, 62.-74. µg/g). Relation of Elemental Concentrations to Toxicity Thresholds for Fish and Piscivorous Wildlife Concentrations of copper and zinc in whole-fish samples from our study were well below literaturebased toxicity thresholds for fishes, wildlife consumers of fish, or both (see Table 4). By comparison, arsenic, cadmium, chromium, lead, mercury, and selenium in whole-fish samples equaled or exceeded the toxicity thresholds, raising the possibility of adverse effects. Arsenic concentrations (measured as total arsenic) in 4 kelp bass from a natural area (NA4, 4 of 10 fish), 14 kelp rockfish from three natural areas (NA1, 1 of 10 fish; NA2, 4 of 10 fish; and NA3, 9 of 10 fish), and 7 Pacific sanddab from an oil platform (PL2, 1 of 8 fish) and a natural area (NA3, 6 of 10 fish) equaled or exceeded the toxic threshold of 2.2-11.6 µg As/g wet weight. Although arsenic concentrations as high as 10.2 µg/g wet weight were recorded during our study (i.e., a sample of kelp rockfish from NA3), the likelihood of toxicity was probably negligible because
