    Department of Environmental Toxicology and Clemson Institute of Environmental Toxicology, Clemson University, Pendleton, SC 29670, USA
    Chemosphere 45:497-506. 2001
    ..The pulse interval between multiple pulses in these experiments was 24 h. Our results suggest that D. magna can withstand an acutely lethal CPF exposure provided that there is adequate time for recovery between exposures...
  2. ncbi request reprint The effect of calcium and magnesium ratios on the toxicity of copper to five aquatic species in freshwater

    ENSR, Fort Collins, Colorado 80521, USA
    Environ Toxicol Chem 21:347-52. 2002
    ..C. dubia, and 28-d-old FHM. The effect of Ca:Mg ratios on copper toxicity changed for D. magna in softer water (90 mg/L as CaCO3) compared with hard water studies...
  3. ncbi request reprint Effect of culture water hardness on the sensitivity of Ceriodaphnia dubia to copper toxicity
    Rami B Naddy
    ENSR International, 4303 West LaPorte Avenue, Fort Collins, Colorado 80521, USA
    Environ Toxicol Chem 22:1269-71. 2003
    ..5-fold less sensitive to copper than those in moderately hard water. However, the hardness of the exposure water had a greater (2.5-fold) effect on copper median effective concentration (EC50s)...
  4. ncbi request reprint Evaluating the role of ion composition on the toxicity of copper to Ceriodaphnia dubia in very hard waters
    Robert W Gensemer
    ENSR International, 4303 West LaPorte Avenue, Fort Collins, CO 80521, USA
    Comp Biochem Physiol C Toxicol Pharmacol 133:87-97. 2002
    ..However, the mechanistic Biotic ligand model generally predicted copper toxicity within +/-2X of observed EC(50) values, and thus may be more useful than hardness for modifying water quality criteria...
  5. ncbi request reprint Chronic toxicity of silver nitrate to Ceriodaphnia dubia and Daphnia magna, and potential mitigating factors
    Rami B Naddy
    ENSR, Fort Collins Environmental Toxicology Laboratory, Fort Collins Colorado 80521, USA
    Aquat Toxicol 84:1-10. 2007
    ..Whole-body Ag concentration in D. magna was positively correlated with increased levels of Ag exposure, however; we observed a non-statistical decrease in whole-body Na levels, an estimator of sodium homeostasis...

    Environ Toxicol Chem 26:1922-30. 2007
    ..These results indicate that the STC study could be used as a surrogate test to estimate chronic toxicity and that the mechanism of chronic silver toxicity may be the same as for acute toxicity...
