Journal ArticleDOI
Applying species-sensitivity distributions in ecological risk assessment: assumptions of distribution type and sufficient numbers of species
Michael C. Newman,David R. Ownby,Laurent C. Mézin,David C. Powell,Tyler R. L. Christensen,Scott Lerberg,Britt-Anne Anderson +6 more
TL;DR: The fit of the lognormal model and required number of individual species values were evaluated with 30 published data sets as mentioned in this paper, and 15 data sets failed a formal test of conformity to a LDA; other distributions often provided better fit to the data than the LDA.
Journal ArticleDOI
Fish (Fundulus heteroclitus) populations with different exposure histories differ in tolerance of creosote‐contaminated sediments
David R. Ownby,Michael C. Newman,Margaret Mulvey,Wolfgang K. Vogelbein,Michael A. Unger,L. Felipe Arzayus +5 more
TL;DR: Differences between fish populations from the two estuaries were larger than differences within the Elizabeth River, and these differences in tolerance were heritable.
Journal ArticleDOI
Accumulation of trinitrotoluene (TNT) in aquatic organisms: Part 1—Bioconcentration and distribution in channel catfish (Ictalurus punctatus)
TL;DR: Although the bioconcentration potential of TNT is very low, future research needs to be conducted to identify the biotransformation products that make up most of the radioactivity in exposed fish and evaluate their potential to promote toxicity.
Journal ArticleDOI
Influence of water quality on silver toxicity to rainbow trout (Oncorhynchus mykiss), fathead minnows (Pimephales promelas), and water fleas (Daphnia magna)
Daniel J. Karen,David R. Ownby,Barry L. Forsythe,Todd P. Bills,Thomas W. La Point,George Cobb,Stephen J. Klaine +6 more
TL;DR: In this article, the authors conducted toxicity bioassays to quantify water quality conditions under which silver, as silver nitrate, is toxic to Oncorhynchus mykiss, Pimephales promelas, and Daphnia magna.
Journal ArticleDOI
Accumulation of trinitrotoluene (TNT) in aquatic organisms: part 2--Bioconcentration in aquatic invertebrates and potential for trophic transfer to channel catfish (Ictalurus punctatus).
TL;DR: The potential of TNT to accumulate in aquatic organisms was assessed by determining bioconcentration factors for TNT and TNT biotransformation products using two benthic invertebrates and determining the bioaccumulation factor due to TNT exposure via feeding for channel catfish.
