ACUTE TOXICITY OF PHENOL AND SUBSTITUTED PHENOLS TO THE FATHEAD MINNOW

The variability of the data on some phenolics makes it difficult to separate toxicity values that vary widely from others because of different test methods rather than different physical properties of the water. This paper reports on an acute test series conducted with a variety (12) of phenolic compounds. Test conditions were kept as uniform as possible so that the toxicities of the compounds could be attributed to the differences in toxicity rather than to differences in test conditions. In addition, the tests provide data on the toxic effects in Lake Superior water. Refs.
