Jh. Lange et Kw. Thomulka, EVALUATION OF MIXTURE TOXICITY FOR NITROBENZENE AND TRINITROBENZENE AT VARIOUS EQUITOXIC CONCENTRATIONS USING THE VIBRIO-HARVEYI BIOLUMINESCENCE TOXICITY TEST, Fresenius environmental bulletin, 7(7-8), 1998, pp. 444-451
This study evaluated toxicity of two chemicals, nitrobenzene and trini
trobenzene, in various percentage equitoxic mixtures using a marine ba
cterium, Vibrio harveyi, as the test organism. Toxicity was evaluated
using the bioluminescent properties of this bacterium. End point measu
rement was a numerical value which was determined by an additive index
procedure. Data from this study suggest that as concentration of the
mixture decreases toxicity to the test organism also becomes less. Use
of toxicity data at high concentrations, which are above that observe
d during pollution events, may provide misleading information on inter
actions.
