Kw. Thomulka et Jh. Lange, TOXICITY OF PHENYLMERCURIC NITRATE USING VIBRIO-HARVEYI AS THE TEST ORGANISM - EVALUATION OF REPRODUCIBILITY, Fresenius environmental bulletin, 4(12), 1995, pp. 731-736
Vibrio harveyi was used in a direct test to evaluate the toxicity of p
henylmercuric nitrate. This study was undertaken to determine the esti
mated median effective concentration (EC50) of this chemical and to ev
aluate this toxicity test by comparing repeated experiments. These res
ults suggest that this direct toxicity test has a reasonable degree of
repeatability. Evaluation of bioluminescence (counts) was determined
to exhibit a normal distribution. The EC50 and its confidence interval
of phenylmercuric nitrate are 0.0012 ppm and 0.0002 ppm, respectively
. Various statistical analyses were performed on the repeated experime
nts for comparison purposes.
