Understanding the toxicity of chemicals to organisms requires considering the molecular
mechanisms involved as well as the relationships between exposure concentration and …

Water quality monitoring tools that rely on data from stress‐response tests with continuous
exposure at constant concentrations are not always appropriately protective when stressor …

The ability to predict the effects of toxicants in organisms with reasonable accuracy depends
to a great extent on the toxico-kinetic models used to describe such effects. Toxic effects of …

Abstract Physiologically based toxicokinetic [(PBTK), or alternatively referred to as
physiologically based pharmacokinetic (PBPK)] models are quantitative descriptions of …

The objectives of this study were to quantify uptake and developmental effects of zinc oxide
nanomaterials (nano-ZnO) on Xenopus laevis throughout the metomormosis process. To …

The issue of toxic metal pollution is a considerable environmental concern owing to its
complex nature, spatial and temporal variability, and susceptibility to environmental factors …

Aquatic organisms living in surface waters experience fluctuating contaminant exposures
that vary in concentration, duration, and frequency. This study characterized the role of …

The effect of waterborne zinc (Zn) on Gyrodactylus population dynamics was studied on
isolated guppies maintained at concentrations ranging from 0 to 240 μg Zn/l. After 1 week …

A healthy terrestrial food web is essential for the sustainable use of soils. Earthworms are
key species within terrestrial food webs and perform a number of essential functionalities …

Some toxicology research in which toxicant exposures are continual (pulsed) rather than
continuous have been reported. A number of toxicity models have been developed for …
