从1988年到1990年，收集了从怀俄明州盐溪油田排放的联合生产盐水的溪流的环境水样并进行了毒性测试。与上游对照相比，暴露于油田下游水体显著（P < 0.05）降低了dubia Ceriodaphnia的存活和繁殖，但黑头鲦鱼（Pimephales promelas）对试验条件不敏感。随着水流的减少，对斑点斑切齿鱼的毒性增加。根据毒性鉴定评价（TIE）方法，毒性不能归因于H2S、微量金属或非极性有机化合物。主要的无机离子（Na+, K+, Cl-， HCO3-和CO3(2-)）似乎解释了观察到的毒性。
Ambient water samples from streams receiving discharges of coproduced brines from the Salt Creek oil field in Wyoming were collected and tested for toxicity from 1988 to 1990. Exposure to waters downstream from the oil field significantly (P < 0.05) reduced survival and reproduction of Ceriodaphnia dubia compared to the upstream control, but fathead minnows (Pimephales promelas) did not appear to be sensitive to the test conditions. Toxicity to Ceriodaphnia dubia increased as stream flow decreased. Toxicity could not be attributed to H2S, trace metals, or nonpolar organic compounds based on toxicity identification evaluation (TIE) methods. Major inorganic ions (Na+, K+, Cl-, HCO3-, and CO3(2-) appeared to account for the observed toxicity.
