Comparative proteomics of copper exposure and toxicity in rainbow trout, common carp and gibel carp.

Species specific differences in transporters, chaperones, metal binding proteins and other targets are important in metal toxicity. Therefore, we have studied the effects of copper exposure on the proteome of gill tissue from Oncorhynchus mykiss, Cyprinus carpio and Carassius auratus gibelio, which have different sensitivities toward copper. Fish were exposed to the Flemish water quality standard for surface waters, being 50μg/L, for 3 days.

Aquatic multi-species acute toxicity of (chlorinated) anilines: experimental versus predicted data.

Aquatic toxicity information is essential in environmental risk assessment to determine the potential hazards and risks of new and existing chemicals. Prediction and modelling techniques, such as quantitative structure activity relationships (QSAR) and species sensitivity distributions (SSDs), are applied to fill data gaps and to predict, assess and extrapolate the toxicity of chemicals. In this study, both techniques (i.

Long-term warm or cold acclimation elicits a specific transcriptional response and affects energy metabolism in zebrafish.

Organisms are often forced to acclimate to changing environmental temperature. Temperature compensation mechanisms have been reported, which enable organisms to minimize some of the temperature related effects. To investigate this process, zebrafish (Danio rerio) were acclimated to a control (26 degrees C), an increased (34 degrees C) or a decreased (18 degrees C) temperature for 4, 14 and 28 days.
