| polybrominated diphenyl ether metabolism in field collected fish from the gila river, arizona, usa--levels, possible sources, and patterns. | polybrominated diphenyl ethers (pbdes) were determined in fish collected from the gila river, arizona, a tributary of the colorado river in the lower part of the colorado river basin. fish samples were collected at sites on the gila river downstream from hayden, phoenix, and arlington, arizona in late summer 2003. the gila river is ephemeral upstream of the phoenix urban area due to dams and irrigation projects and has limited perennial flow downstream of phoenix due to wastewater and irrigation ... | 2013 | 22939514 |
| patterns of metal composition and biological condition and their association in male common carp across an environmental contaminant gradient in lake mead national recreation area, nevada and arizona, usa. | there is a contaminant gradient in lake mead national recreation area (lmnra) that is partly driven by municipal and industrial runoff and wastewater inputs via las vegas wash (lvw). adult male common carp (cyprinus carpio; 10 fish/site) were collected from lvw, las vegas bay (receiving lvw flow), overton arm (oa, upstream reference), and willow beach (wb, downstream) in march 2008. discriminant function analysis was used to describe differences in metal concentrations and biological condition o ... | 2012 | 22206697 |
| chemical contaminants, health indicators, and reproductive biomarker responses in fish from the colorado river and its tributaries. | common carp (cyprinus carpio), black bass (micropterus spp.), and channel catfish (ictalurus punctatus) were collected from 14 sites in the colorado river basin (crb) to document spatial trends in accumulative contaminants, health indicators, and reproductive biomarkers. organochlorine residues, 2,3,7,8-tetrachlorodibenzo-p-dioxin-like activity (tcdd-eq), and elemental contaminants were measured in composite samples of whole fish, grouped by species and gender, from each site. selenium (se) and ... | 2007 | 17418376 |
