A framework for the development of standard methods to evaluate the toxicity of petroleum hydrocarbons on aquatic organisms . : Fs70-6/2017-053E-PDF

“This Science Advisory Report (SAR) provides a proposed framework on standard methods to evaluate the toxicity of petroleum on aquatic organisms to produce more comparable results, improve the consistency between studies, and collect more relevant data. There is increasing oil and gas resource development and transportation of petroleum products in Canada. This increases the potential for aquatic contamination in more diverse receiving environments. Therefore, there is a requirement for oil toxicity testing to support decision-making and spill preparedness and response. A guidance document for preparing test media to assess oil toxicity in sea water exists but has not been updated since 2005. It was not developed for heavy oils or use in freshwater. The proposed framework improves guidance on experimental designs, physical and chemical characterization of test oils, and preparation of physically- and chemically-dispersed oil, characterizing test solutions, toxicity testing and reporting requirements"--Summary, p. 2.
