| Abstract |
Evaluation of the algal assay bottle test and its relationship to the trophic state or nutrient levels of surface waters was examined in 44 lakes impoundments, and rivers in North Carolina in 345 separate assay sets. Of particular concern was the evaluation of the significance of the pretreatment procedure, autoclaving or filtration, upon growth of the reseeded alga in relationship to the original water quality. A limnological data profile was developed for each of the bodies of water sampled. A data processing procedure was used to establish the relationship between water quality data and algal cell density, chlorophyll a and productivity. |
