| Notes | Studied logging debris for Douglas fir, red alder and Western hemlock, to learn the toxicity of large amounts of debris in small mountain streams. "Specific concentrations of given leachates were found to be toxic to fish. However, the bioassay test performed only measured the effect of the leachate on fish. Under natural conditions an oxygen stress may be created due to the presence of debris." (p.114) Stream temperature affects the toxicity of the debris. Major professor was George W. Brown III. |
