- Abstract
This article tests zinc toxicity to luminescent bacteria as a function of sodium chloride concentration. The results have been treated statistically, together with previously reported values for lead, cadmium and nickel in the same medium, to correlate the toxicity as a function of chloro-metal speciation complexes. Because the general presence of metals in our environment studies of their toxicity have become important. In this context, the Microtox assay has been used to screen the toxicity of some metallic salts. In this method toxicity is measured in a 2% sodium chloride medium using the luminescent marine Vibrio flscheri. When the bacteria are exposed to a toxic sample the emitted light is reduced in relation to the potency of the sample.
