The effect of selected insecticides upon biochemical oxidation

Creator:

Norris, Francis Warren, Jr.

Abstract:

A study to determine the effect of certain synthetic organic insecticides on the Biochemical Oxygen Demand (BOD) Test was performed. BOD tests on a standard glucose-glutamic acid substrate were conducted while in the presence of dieldrin, dichlorodiphenyltrichloroethane (DDT), or diazinon. From the BOD data, the following parameters were obtained: 1....

Modeling the impact of logging debris on the dissolved oxygen balance of small mountain streams

Creator:

Berry, John David

Abstract:

Previous research has indicated that considerable amounts of finely divided slash accumulate in small mountain streams following timber harvesting. The subsequent biological decomposition of this organic matter can result i.n the reduction of dissolved oxygen (DO) concentration to levels as low as 0.6 ppm. These DO levels are lethal to...
