Toxicity and bioaccumulation of waterborne and dietary selenium in juvenile bluegill (Lepomis macrochirus)
Abstract Juvenile bluegill (Lepomis macrochirus) were exposed to waterborne selenium as a 6:1 mixture of selenate to selenite (as Se) for 60 d and to dietary seleno- l -methionine for 90 d. MeasuredExpand

Effect of dietary selenium on the reproductive success of bluegills (Lepomis macrochirus)
The effects of dietary and waterborne selenium on the reproductive success of adult bluegills were evaluated in a chronic toxicity study. Before spawning, two-year-old bluegills were exposed for 60 dExpand

Influence of sediment on the fate and toxicity of a polyethoxylated tallowamine surfactant system (MON 0818) in aquatic microcosms.
The fate and toxicity of a polyethoxylated tallowamine (POEA) surfactant system, MON 0818, was evaluated in water-sediment microcosms during a 4-d laboratory study. A surfactant solution of 8 mgExpand

Toxicity of fluridone to aquatic invertebrates and fish
The acute and chronic toxicities of the herbicide fluridone to aquatic invertebrates and fish were evaluated. The acute median lethal concentrations (LC50s) of fluridone were 4.3 ± 3.7 mg/L (x±SD)Expand

Survival, sublethal responses, and tissue residues of Atlantic salmon exposed to acidic pH and aluminum
Abstract Early life stages of Atlantic salmon (Salmo salar) were continuously exposed to pHs ranging from 4.5 to 7.2 in one study, and to Al concentrations ranging from 33 to 264 μg/l at pH 5.5 in aExpand
