Description:

This paper summarizes several unsuccessful attempts to develop Toxicity Identification and Evaluation (TIE) manipulations for aqueous samples during the first 5 years of our research. The first part of the paper explores irradiation as a sterilization technique to discern if sample toxicity was due to a pathogen. The second part of the paper summarizes our attempts to use buffers to maintain seawater pH at 7 and 9 for use in the graduated pH method.
