Abstract

The toxicity of nickel and lead compounds has been evaluated in NaCl and NaClO4 solutions by using the MicrotoxR bioassay. The aim of this work was to assess the toxicity of the different species in solution when varying the concentration of the medium. A modified Microtox protocol which enables the pH to be constant in all the cuvettes during analysis has been used. The positively charged species (Ni2+, Pb2+, PbCl+) were found to contribute more to the toxicity of Ni and Pb in NaCl while in NaClO4 solutions free metal was the responsible species. In all media studied, Pb compounds were the most toxic and provoked a quick response of the bacteria.
