Combinations of copper (0–90 μg/1) and zinc (0–1200 μg/L) acted in an additive fashion when tested by Microtox®, decreasing the luminescence of the marine bacterium Photobacterium phosphoreum after a 30-min exposure. Acetophenone (0–18 mg/L)

An overall strategy of regulation should always include three tactics: (1) discharge limits at the end of the effluent pipe, based on a reasonable level of industrial technology; (2) water-quality-based limits, strict enough to eliminate sublethal ef

Lethal tolerance to copper by rainbow trout (Salmo gairdneri) increased by 60, 106, and 90% following 3-wk exposures to 0.29, 0.40, and 0.59 of the mean control incipient lethal level (ILL), 330 μg Cu/L (SD = 30; n = 25). A lower level of exposure,

Continuous exposure to 30% treated refinery effluent had severe effects on growth of rainbow trout during 44 days; their size at the end of the experiment was not significantly greater than at the beginning. Effluent at 10% concentration also resulte

Seven-day LC50s of vanadium pentoxide for 2.5-g trout showed only a small range, from 1.9 to 6.0 mg V I−1, in tests at all 12 combinations of 30, 100 and 355 mg 1−2 total hardness with pH 5.5, 6.6, 7.7 and 8.8. Toxicity decreased from low to high

Rainbow trout were exposed for 3 wk to copper at 0.09, 0.18, 0.29, 0.40, or 0.59 of the mean control incipient lethal level (ILL) of copper. Whole body copper concentration increased with both exposure concentration and time. Mean residues stabilized

After 1, 2, 3 and 5 weeks of pre-exposure to 0.31 mg l −1 of parathion, rainbow trout ( Salmo gairdneri ) did not change their tolerance of lethal levels of the organophosphate insecticide. This pre-exposure concentration represents 0.25 of the mea
