Interspecies scaling of the bioaccumulation of lipophilic xenobiotics in fish: An example using trifluralin
Environmental Toxicology and Chemistry - Tập 18 Số 7 - Trang 1440-1449 - 1999
Irvin R. Schultz, William L. Hayton
AbstractA poorly understood factor that may influence differences in the accumulation of a xenobiotic among fishes is interspecies differences in physiology. We have extensively studied the uptake, distribution, and excretion kinetics of the lipophilic herbicide trifluralin (TF) in fish, using a static water exposure system and compartmental toxicokinetic models.

Inhibition of testicular growth in rainbow trout (Oncorhynchus mykiss) exposed to estrogenic alkylphenolic chemicals
Environmental Toxicology and Chemistry - Tập 15 Số 2 - Trang 194-202 - 1996
Susan Jobling, John P. Sumpter, Dave Sheahan, Julia A. Osborne, Peter Matthiessen
AbstractIt is becoming evident that an increasing number of widely used industrial and agricultural chemicals are estrogenic. The biodegradation products of a major group of nonionic surfactants, the alkylphenol polyethoxylates, are one such group. Some of these chemicals are widespread aquatic pollutants, and bioconcentrate in aquatic biota. Exposure of male rainb...... hiện toàn bộ
Acute and chronic effects of pulse exposure of Daphnia magna to dimethoate and pirimicarb
Environmental Toxicology and Chemistry - Tập 25 Số 5 - Trang 1187-1195 - 2006
T.H. Andersen, Rikke Tjørnhøj, Leah Wollenberger, Tina slothuus, Anders Baun
AbstractShort‐term ( <48 h) and long‐term (21 d) effects of dimethoate and pirimicarb were studied in Daphnia magna exposed to pulses of 0.5 to 8 h in duration. During a 21‐d postexposure observation period, the following parameters were monitored: Mortality, mobility, day for first offspring, animal size, weight of offspring and adult...... hiện toàn bộ
A comparison of nanoparticle and fine particle uptake by Daphnia magna
Environmental Toxicology and Chemistry - Tập 28 Số 10 - Trang 2142-2149 - 2009
Philipp Rosenkranz, Qasim Chaudhry, Vicki Stone, Teresa F. Fernandes
AbstractThe use of nanoparticles in various applications is steadily on the rise, with use in a range of applications, including printer toner, sunscreen, medical imaging, and enhanced drug delivery. While research on human effects via, for example, inhalation is relatively well developed, the environmental assessment of nanoparticles is in its infancy. In the pres...... hiện toàn bộ
Long‐term neurobehavioral effects of perinatal polychlorinated biphenyl (PCB) exposure in monkeys
Environmental Toxicology and Chemistry - Tập 10 Số 6 - Trang 747-756 - 1991
Susan L. Schantz, Edward D. Levin, Robert E. Bowman
AbstractIn recent years, there has been growing concern about the potential long‐term neurobe‐havioral effects of perinatal polychlorinated biphenyl (PCB) exposure. We have addressed this issue in a series of studies at the Harlow Primate Laboratory. Offspring of rhesus monkeys (Macaca mulatto) exposed to commercial PCB mixtures (Aroclor ...... hiện toàn bộ
Pesticide concentration patterns in agricultural drainage networks in the lake Erie Basin
Environmental Toxicology and Chemistry - Tập 12 Số 1 - Trang 13-26 - 1993
R. Peter Richards, David B. Baker
AbstractThis paper presents information on pesticide concentrations in Lake Erie tributaries draining agricultural watersheds, information distilled from data sets spanning nearly a decade and including up to 750 samples per tributary. Pesticide concentrations are strongly skewed and approximately lognormal. Average concentrations in tributaries are correlated with...... hiện toàn bộ
Presence and distribution of wastewater‐derived pharmaceuticals in soil irrigated with reclaimed water
Environmental Toxicology and Chemistry - Tập 25 Số 2 - Trang 317-326 - 2006
Chad A. Kinney, Edward T. Furlong, Stephen L. Werner, Jeffery D. Cahill
AbstractThree sites in the Front Range of Colorado, USA, were monitored from May through September 2003 to assess the presence and distribution of pharmaceuticals in soil irrigated with reclaimed water derived from urban wastewater. Soil cores were collected monthly, and 19 pharmaceuticals, all of which were detected during the present study, were measured in 5‐cm ...... hiện toàn bộ
SEDIMENT SORPTION COEFFICIENT MEASUREMENTS FOR FOUR PHTHALATE ESTERS: EXPERIMENTAL RESULTS AND MODEL THEORY
Environmental Toxicology and Chemistry - Tập 14 Số 9 - Trang 1477 - 1995
Mark D. Williams, William J. Adams, Thomas F. Parkerton, Gregory R. Biddinger
Analysis of glutathione endpoints for measuring copper stress in Chlamydomonas reinhardth
Environmental Toxicology and Chemistry - Tập 26 Số 8 - Trang 1563-1571 - 2007
Tasha Stoiber, Martin M. Shafer, Dawn A. Karner Perkins, Jocelyn D.C. Hemming, David E. Armstrong
AbstractGlutathione (GSH) is the most abundant nonprotein thiol in eukaryotic cells and it protects cells by functioning as an antioxidant and a metal‐binding ligand. Because glutathione readily undergoes oxidation‐reduction reactions to combat oxidative stress, intracellular ratios of the reduced (GSH) to the oxidized (GSSG) forms of glutathione may serve as an im...... hiện toàn bộ
Exposure assessment of 17α‐ethinylestradiol in surface waters of the United States and Europe
Environmental Toxicology and Chemistry - Tập 28 Số 12 - Trang 2725-2732 - 2009
Robert E. Hannah, Vincent J. D’Aco, Paul Anderson, Mary Buzby, Daniel J. Caldwell, Virginia Cunningham, Jon F. Ericson, Andrew C. Johnson, Neil J. Parke, John Samuelian, John P. Sumpter
AbstractAn evaluation of measured and predicted concentrations of 17α‐ethinylestradiol in surface waters of the United States and Europe was conducted to develop expected long‐term exposure concentrations for this compound. Measured environmental concentrations (MECs) in surface waters were identified from the literature. Predicted environmental concentrations (PEC...... hiện toàn bộ
