Abstract

Two reference toxicants (potassium chloride-KCl and sodium chloride-NaCl) were used in the present study in order to assess the sensitivity of the microcrustacean cladocera Ceriodaphnia dubia. Chronic toxicity tests were carried out with those two salts and the sensitivity expressed as IC50;7D - concentration that causes inhibition of 50% of reproduction ability, in seven days exposure time. The medium values estimated for IC50;7D were 200.70 and 499.60 to KCl and NaCl, respectively. Those data have demonstrated that KCl can be more restrictive and more suitable than NaCl, when used as standard reference toxicant for plotting control charts of sensitivity
