Results of Toxicity Studies Conducted on Ceriodaphnia dubia and Daphnia ambigua in Support of an Alternate Species Demonstration, January - June 2000

PDF Version Also Available for Download.

Description

In 1997, the Savannah River Site completed toxicity testing studies on an alternate species, Daphnia ambigua, that we have proposed for use as a toxicity testing organism at SRS. We demonstrated that this species could be cultured in the laboratory and that it was at least as sensitive as Ceriodaphnia dubia to a broad range of toxicants (Specht and Harmon, 1997; Harmon, 1998; Harmon and Specht, 1998; Harmon, Specht and Chandler, 1999). However, it performed better that C. dubia in very soft water, which is representative of many SRS effluents and receiving waters. In January 2000, representatives from SRS met ... continued below

Description

In 1997, the Savannah River Site completed toxicity testing studies on an alternate species, Daphnia ambigua, that we have proposed for use as a toxicity testing organism at SRS. We demonstrated that this species could be cultured in the laboratory and that it was at least as sensitive as Ceriodaphnia dubia to a broad range of toxicants (Specht and Harmon, 1997; Harmon, 1998; Harmon and Specht, 1998; Harmon, Specht and Chandler, 1999). However, it performed better that C. dubia in very soft water, which is representative of many SRS effluents and receiving waters. In January 2000, representatives from SRS met with representatives from U.S. EPA Region 4 and SCDHEC to discuss data needs related to EPA's consideration of SRS's request to use the alternate species (D. ambigua) for routine toxicity testing at SRS. SRS contends that the very low water hardness of some of its effluents is responsible for toxicity failures because the species recommended by the EPA (C. dubia) does not reproduce well in waters that have very low hardness.
