title: Toxicity of cadmium species on luminescent bacteria.
abstract: The toxicity of cadmium compounds against luminescent bacteria has been measured using the Microtox(R) toxicity bioassay and has been related to the cadmium species. Since the Microtox(R) test is carried out in NaCl (2%) and cadmium forms stable chloro complexes, NaNO(3) and NaClO(4) have been tested successfully as alternative to sodium chloride to provide the adequate osmotic protection of the bacteria. The influence of medium and ionic strength as well as different exposure times on EC(50) values has been evaluated.
