| relative sensitivity of three endangered fishes, colorado squawfish, bonytail, and razorback sucker, to selected metal pollutants. | the acute toxicity of four metal pollutants to larval and juvenile stages of endangered colorado squawfish (ptychocheilus lucius), bonytail (gila elegans), and razorback sucker (xyrauchen texanus) were determined in a water quality representative of that in the green river, utah. the rank order of toxicity (96-hr lc50) of the metals to all species and life stages from most toxic to least toxic was mercury (57-168 micrograms/liter) > cadmium (78-168 micrograms/liter) > hexavalent chromium (32,000 ... | 1997 | 9262959 |
| hazard assessment of inorganics to three endangered fish in the green river, utah. | acute toxicity tests were conducted with three life stages of colorado squawfish (ptychocheilus lucius), razorback sucker (xyrauchen texanus), and bonytail (gila elegans) in a reconstituted water quality simulating the middle part of the green river of utah. tests were conducted with boron, lithium, selenate, selenite, uranium, vanadium, and zinc. the overall rank order of toxicity to all species and life stages combined from most to least toxic was vanadium = zinc > selenite > lithium = uranium ... | 1995 | 7539367 |
