Expression of stress proteins in cultured human cells as a sensitive indicator of metal toxicity
Human cell lines cultured under standardized conditions are found to react after a wide variety of aggressive but sub-lethal treatments by expressing stress proteins, mainly of the HSP68, HSP70 and HSP90 famil...

Toxicity of cadmium species on luminescent bacteria
The toxicity of cadmium compounds against luminescent bacteria has been measured using the MicrotoxR toxicity bioassay and has been related to the cadmium species. Since the MicrotoxR test is carried out in NaCl ...

Effect of pH on Arsenate and Arsenite Toxicity to Luminescent Bacteria (Vibrio fischeri)
Arsenic is an abundant metalloid and a dangerous pollutant when in solution under the arsenate or arsenite forms—As(V) and As(III), respectively. Since its biological effects are expected to depend on the oxid...

Effect of Cadmium(II), Chromium(VI), and Arsenic(V) on Long-Term Viability- and Growth-Inhibition Assays Using Vibrio fischeri Marine Bacteria
As a complement to previous results obtained using the standard Microtox acute-toxicity test, which is based on measuring the rapid decrease of bioluminescence (5 to 30 minutes of exposure) in Vibrio fischeri bac...
