| 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 |
| environmental contaminants and biomarker responses in fish from the rio grande and its u.s. tributaries: spatial and temporal trends. | we collected, examined, and analyzed 368 fish of seven species from 10 sites on rivers of the rio grande basin (rgb) during late 1997 and early 1998 to document temporal and geographic trends in the concentrations of accumulative contaminants and to assess contaminant effects on the fish. sites were located on the mainstem of the rio grande and on the arroyo colorado and pecos river in texas (tx), new mexico (nm), and colorado. common carp (cyprinus carpio) and largemouth bass (micropterus salmo ... | 2005 | 16227080 |
