Toxicity of organic selenium in the diet to chinook salmon
The toxicity of two organoselenium diets was evaluated in 90- to 120-d partial life cycle tests with two life stages of chinook salmon (Oncorhynchus tshawytscha Walbaum). One of the diets containedExpand

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

Sensitivity of brook trout to low pH, low and elevated aluminum concentrations during laboratory pulse exposures
Yolk-sac larvae of brook trout (Salvelinus fontinalis) were exposed to four sequential low pH and calcium (Ca) pulses, nominally ranging from pH 6.5 to 4.0 in 0.5 pH unit increments, with and withoutExpand

Concentrations of Boron, Molybdenum, and Selenium in Chinook Salmon
Abstract The concentrations of boron, molybdenum, and selenium in young chinook salmon Oncorhynchus tshawytscha were determined in three partial life cycle chronic toxicity studies. In each study,Expand

Interactive Effects of Acidity and Aluminum Exposure on the Life Cycle of the Midge Chironomus riparius (Diptera)
ABSTRACT The chronic toxicity of acidic pH and the toxicity of aluminum at pH 5.6 and pH 5.0 to the midge Chironomus riparius were determined in 30–day flow–-through exposures. The survival of midgesExpand

Communications: Blood Chemistry of Laboratory-Reared Golden Trout
Abstract Golden trout Oncorhynchus aguabonita obtained from a wild stock as fertilized eggs were reared in the laboratory for 21 months. The laboratory-reared golden trout in our study reached sexualExpand

Gas-liquid chromatographic determination of S,S,S-tributyl phosphorotrithioate (DEF) in water and fish tissue.
Methods are described for determination of S,S,S-tributylphosphorotrithioate (DEF) at levels as low as 5 parts per billion in fish and 200 parts per trillion in water. Fish tissue extracts areExpand
