| evaluating the trophic transfer of selenium in aquatic ecosystems using caged fish, x-ray absorption spectroscopy and stable isotope analysis. | this research evaluated the dominant exposure pathways with regard to the bioaccumulation and trophic transfer of selenium (se) in caged small-bodied fish inhabiting the receiving waters of a uranium-processing mill in northern saskatchewan, canada. a 21-day cage study was conducted using wild naïve lake chub (couesius plumbeus) collected from a reference lake and caged in a reference and an exposure lake downstream of the mill discharge. caged fish were fed commercially produced chironomus spp. ... | 2011 | 21757232 |
| selenium uptake and speciation in wild and caged fish downstream of a metal mining and milling discharge. | the aim of this research was to evaluate the dominance of the feeding pathway with respect to selenium (se) uptake and speciation in fish inhabiting the receiving waters downstream of a uranium processing mill in northern saskatchewan, canada. the experimental design included analysis of se in the predominant fish species located in the study area, a caging validation study using wild, naïve (i.e., collected from a reference lake) lake chub (couesius plumbeus) and spottail shiner (notropis hudso ... | 2011 | 21419485 |
