The Relative Resistances of Seventeen Species of Fish to Petroleum Refinery Effluents and a Comparison of Some Possible Methods of Ranking Resistances
Eighteen species of fish including a reference species, were subjected to toxicity bioassay using petroleum refinery effluent as a toxicant. Twenty-four-hour and 96-hour median tolerance limits Were calculated using a straight-line graphical interpolation based on ten specimens per concentration with a replication. Collection, laboratory, and bioassay histories were recorded for each test species and a general suitability statement made for each. Twenty-four-hour and 96-hour adjusted resistances obtained by the “Preadjusted-Abbreviated Doolittle” method were subjected to analysis of...
