Are PFCAs Bioaccumulative? A Critical Review and Comparison with Regulatory Criteria and Persistent Lipophilic Compounds
TL;DR: The bioaccumulation potential of perfluorinated acids with seven fluorinated carbons or less appears to be several orders of magnitude lower than "legacy" persistent lipophilic compounds classified as bioaccuulative.
Methods for measuring the toxicity and bioaccumulation of sediment-associated contaminants with freshwater invertebrates
Christopher G. Ingersoll,Gerald T. Ankley,G.A. Burton,F.J. Dwyer,Robert A. Hoke,Teresa J. Norberg-King,P. V. Winger +6 more
TL;DR: In this article, the authors describe protocols for testing freshwater organisms in the laboratory to evaluate the toxicity or bioaccumulation of contaminants associated with whole sediments, including the amphipod Hyalella azteca and midge Chironomus tentans.
Journal ArticleDOI
Development of a base set of toxicity tests using ultrafine TiO2 particles as a component of nanoparticle risk management.
David B. Warheit,Robert A. Hoke,Carol Finlay,E. Maria Donner,Kenneth L. Reed,Christie M. Sayes +5 more
TL;DR: The toxicity results of a base set of hazard tests on a set of newly developed, well-characterized, ultrafine TiO(2) (uf-TiO( 2)) particle-types demonstrated low hazard potential in mammals or aquatic species following acute exposures to the ultrafineTiO (2) particle- types tested in this program.
Journal ArticleDOI
Toxicogenomics in regulatory ecotoxicology.
Gerald T. Ankley,George P. Daston,Sigmund J. Degitz,Nancy D. Denslow,Robert A. Hoke,Sean W. Kennedy,Ann L. Miracle,Edward J. Perkins,Jason Snape,Donald E. Tillitt,Charles R. Tyler,Donald J. Versteeg +11 more
TL;DR: Roles of toxicogenomics in the field of regulatory ecotoxicology are considered, current limitations in the science and practice of genomics are explored, and possible avenues to approach and resolve some of the major challenges are proposed.
Journal ArticleDOI

TL;DR: Environmental realism in ENM hazard assessments should involve greater coordination among ENM quantitative analysts, exposure modelers, and ecotoxicologists, across government, industry, and academia.
