Atrazine reduces reproduction in fathead minnow (Pimephales promelas).
Atrazine, the widely used herbicide, has shown to affect the hypothalamus-pituitary-gonad axis in certain vertebrate species, but few studies have examined reproductive effects of this chemical on fish. Our study was designed to evaluate a population endpoint (egg production) in conjunction with histological (e.g., gonad development) and biochemical (e.g., hormone production) phenotypes associa...
متن کاملHistopathology of fathead minnow (Pimephales promelas) exposed to hydroxylated fullerenes
Hydroxylated fullerenes are reported to be very strong antioxidants, acting to quench reactive oxygen species, thus having strong potential for important and widespread applications in innovative therapies for a variety of disease processes. However, their potential for toxicological side effects is still largely controversial and unknown. Effects of hydroxylated fullerenes C60(OH)24 on the fat...
متن کاملDescription and evaluation of a short-term reproduction test with the fathead minnow (Pimephales promelas).
Due to the time and expense associated with full life-cycle testing, most current toxicity tests with fish do not explicitly consider reproductive output as an endpoint but, rather, focus on early life-stage survival and development. However, some classes of chemicals could adversely impact reproduction at concentrations below those that affect development. Further, estimates of the effects of ...
متن کاملSublethal toxicity of commercial insecticide formulations and their active ingredients to larval fathead minnow (Pimephales promelas).
Toxic effect concentrations of insecticides are generally determined using the technical grade or pure active ingredient. Commercial insecticide formulations, however, contain a significant proportion (>90%) of so-called inert ingredients, which may alter the toxicity of the active ingredient(s). This study compares the sublethal toxicity of two insecticides, the pyrethroid bifenthrin, and the ...
متن کاملPredicting Modes of Toxic Action from Chemical Structure: Acute Toxicity in the Fathead Minnow (Pimephales Promelas)
In the field of aquatic toxicology, quantitative structure–activity relationships (QSARs) have developed as scientifically credible models for predicting the toxicity of chemicals when little or no empirical data are available. In recent years, there has been an evolution of QSAR development and application from that of a chemical-class perspective to one that is more consistent with assumption...
