✦ Synopsis
This investigation evaluated the effects of sand and EDTA on the toxicity of 24 metallic salts on the bioluminescent bacterium Vibrio harveyi, Toxicity end points were reported as either median ( ) effective concentration EC or effective concentration at 20%. Sand and EDTA individually and in 50 sequential combination generally reduced toxicity of metals tested in this system. When comparing treatments of sand without EDTA and sand / EDTA, some chemicals exhibited lower toxicity while others had increased toxicity. Each chemical appears to have its own unique characteric for toxicity when evaluated using the test conditions with this organism.
