  The Threshold Approach for Acute Fish Toxicity Testing GENERAL CONSIDERATIONS 1. In the interest of animal welfare and efficient use of resources, it is important to avoid the unnecessary use of animals whenever possible. In the field of aquatic toxicology, this especially applies to the acute toxicity testing of fish according to OECD TG 203. The

  Whole Effluent Toxicity Testing (Biomonitoring) Applicability Whole effluent toxicity (WET) testing, also known as biomonitoring, is required in permits for dischargers whose effluent has a significant potential to exert toxicity in the receiving water (See § 307.6(e)(2)(A) of the Standards). WET testing directly measures a discharge’s aggregate

  The main driver for aquatic toxicity testing is the EPA IPPC licensing Framework. Some landfill sites require toxicity testing to compliment the chemical analysis to assess suitability of the solid waste for land-filling. In 2012 SATL received 185 samples, 70% of which were effluents, 18% solid wastes and 12% others (Figure 2).
