摘要: The objectives of this study were to evaluate the influence natural oil sands on early developmental stages white sucker (Catostomus commersoni) and determine whether biochemical responses in species similar native fish caught Athabasca Oil Sands area. Early life stage (ELS) sediment toxicity tests conducted using controls, reference sediments, sands, industrially contaminated (wastewater pond) sediments collected from sites along River, Alberta (Canada). Eggs larvae observed for mortality, hatching, deformities, growth, cytochrome P-4501A (CYP1A) activity immunohistochemistry. E-Nat-, S-Nat-, wastewater pond sediment-exposed groups showed significant premature reduced exposure-dependent increases ELS mortality larval malformations relative controls. most common deformities included edemas (pericardial, yolk sac, subepidermal), hemorrhages, spinal defects.
