Bioavailable Phosphorus In The Bear River System, Utah, Kenneth Warren Barker
Bioavailable Phosphorus In The Bear River System, Utah, Kenneth Warren Barker
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The bioavailable fraction of phosphorus (BAP) in the lower Bear River system waters was investigated. BAP plays a critical role as the limiting nutrient for algal production and eutrophication in proposed reservoirs in the Bear River system. The Bear River system has a hardness ranging between 180-240 mg/L as CaCO3 which significantly affects BAP.
BAP estimation was done by a modified Selenastrum capricornutum Printz Algal Assay Bottle Test. The algal bioassay is considered the best estimator of BAP because no chemical tests or indicator parameters are available. Autoclaving and UV radiation were found to be unacceptable means for sterilization …
