Toxicity identification evaluations of produced-water effluents

摘要

Tocicity identification evaluations (TIEs) were performed on 14 produced-water (PW) samples of various salinities from inland and offshore oil-and gas-production facilities operated by different companies in Wyoming, Texas, California, and Louisiana (USA) to evaluate the efficacy of TIE procedures in determining potential toxicants in PW effluents. The research involved acute (24, and 480h) freshwater and marine toxicity tests on whole PW and Pw fractions generated y standard U. S. Environmental Protection Agency and PW-specific fractionation schemes.
