Biochemical and physiological indicators of behavioral impairment in salmonids exposed to chlorpyrifos and copper

Creator:

Sandahl, Jason

Abstract:

The purpose of this work was to determine if environmentally-relevant concentrations of chlorpyrifos and copper, two commonly detected chemicals in Western surface waters, can negatively impact the biological health of salmonids. Both compounds are highly neurotoxic to fish, but each with distinct biological target sites and mechanisms of action. We...

Effects of esfenvalerate on native macroinvertebrates representative of Pacific Northwest streams

Creator:

Johnson, Katherine R.

Abstract:

Aquatic insects are essential components of healthy stream ecosystems, contributing to nutrient cycling, trophic dynamics and other ecological functions. Aquatic insect species, particularly those in the orders Ephemeroptera, Plecoptera and Trichoptera (EPT taxa) are however, extremely sensitive to insecticide contamination. Given that urban and agricultural use of synthetic pyrethroid insecticides...

Environmental estrogens and skeletal development disruption in the fathead minnow : A teleost model of vertebrate developmental toxicity

Creator:

Warner, Kara E.

Abstract:

Natural and synthetic estrogenic compounds detected in surface waters have been linked to endocrine signaling disruption in several species. Endogenous estrogen contributes to cartilage and bone deposition during development in vertebrates, and is susceptible to perturbation from xenoestrogens. The goals of this work were to develop a teleost model to...
