Abstract The US Environmental Protection Agency (EPA) has developed a 7‐day
Ceriodaphnia dubia survival and reproduction test for measuring the toxicity of effluents …

Maintenance of chemical concentrations during toxicity tests is essential to determine the
intrinsic toxicity of a material. For compounds that are sorptive, rapidly biodegraded, volatile …

MATERIALS AND METHODS Ceriodaphnia dubia (J. Richard 1894; identified by D. Berner,
Temple University, Philadelphia, Pennsylvania) cultures producing the animals used in the …

The sensitivity of Daphnia magna and Ceriodaphnia dubia to various levels of carbonate
alkalinity and to the reference toxicant, NaCl, were examined in reconstituted water using …

Different renewal diet frequency procedures of Ceriodaphnia dubia were evaluated with
different culture stages: intervening cultures and pilot tests (equivalent to controls in a …

This study evaluated the technical feasibility of a shorter alternative to the US Environmental
Protection Agency (EPA)‐recommended 7‐d chronic toxicity test with Ceriodaphnia dubia …

The three brood Ceriodaphnia dubia test was carried out three nonconsecutive times, each
period being separated by the previous one by three weeks. The toxicant studied was …

The effects of mineral salts constituting water hardness on fecundity of Daphnia magna were
assessed. Of the salts tested, increased concentrations of NaHCO 3 and MgSO 4 had no …

The purpose of this study was to evaluate the effects of four diets on the results of seven-day
Ceriodaphnia dubia toxicity tests. Survival and reproduction were used as indices to detect …

In aquatic toxicology experiments, organisms are randomly assigned to an exposure group
that receives a particular concentration level of a toxicant (including a control group with no …
