This manual describes procedures for characterizing the physical/chemical nature of toxicants in acutely toxic effluent samples. To detect the presence and potency of the toxicants as the sample is manipulated, the measurement of toxicity using organisms is helpful. The final step is to separate the toxicants from other sample constituents to simplify the analytical process. Usually the toxicants must be concentrated for analysis. Sample manipulations to alter toxicity include: sparging, pH change, filtration, solid-phase extraction and addition of chelating and reducing agents. The results will often reveal information about the physical/chemical characteristics of the toxicants.
