Gas chromatographic and mass spectrometric determination of some resin and fatty acids in pulpmill effluents as their pentafluorobenzyl ester derivatives / by Hing-Biu Lee, Thomas E. Peart and John M.... : En13-5/89-125E-PDF

"The toxicity of pulpmill wastes to fish has long been established. Among the toxic constituents in effluents, resin acids are known as the major contributors of the toxicity since they are present at high concentrations and have similar toxicity as the chlorinated phenolics. In the past, the analytical methodology employed for the determination of resin acids and a few other fatty acids has not been sensitive enough for many monitoring applications such as the measurement of final effluents discharging into the environment. We have now developed an analytical method for these acids which is about 100 times more sensitive than the existing methodology"--Management Perspective.
