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 …

Effectively and accurately assessing the toxicity of chemicals and their impact on the
environment continues to be an important concern in ecotoxicology. Single experiments …

A model for Ceriodaphnia dubia reproductive toxicity outcomes is presented. This model
assumes that the number of young is a Poisson‐distributed random variable and that the …

An analysis of sample size requirements for the Ceriodaphnia dubia reproduction toxicity
test is presented. Sample size requirements for detecting nominally specified biological …

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

Abstract The U S. Environmental Protection Agency (EPA) has developed a 7‐d toxicity test
to evaluate effects of effluents on Ceriodaphnia dubia survival and reproduction. This study …

A 4‐d survival and reproduction toxicity test utilizing Ceriodaphnia dubia has been
developed and evaluated. This toxicity test has been compared to the standard 7‐d test …

Chronic toxicity tests using Ceriodaphnia dubia are conducted across the United States by
facilities releasing wastewaters into bodies of freshwater, as well as by the appropriate …

Seven‐day tests with Ceriodaphnia dubia are commonly used to estimate toxicity of effluents
or receiving waters but can sometimes yield no toxicity outcomes even if pollutants are …

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 …
