||Corals were exposed to drilling mud for 24 hr and then allowed to recover for 48 hr in clean seawater. Depending on the concentration and the mud used, exposure produced either an increase or decrease in free amino acid (FAA) pool size. Aspartate was affected to a greater degree than other amino acids. No clear instance of recovery could be ascertained after 48 hr in clean seawater. In several cases, corals, apparently unaffected by a 24 hr exposure, nevertheless suffered significant changes in the FAA pool during the 48 hr recovery period. Thus, the degree of toxicity of the drilling mud could not be accurately predicted from the 24 hr exposure data. In many cases, the choice of a normalizing parameter determined whether two sets of data were significantly different or not. Accurate effects assessment depends on a comparison of several methods of normalization to confirm statistical results. (Copyright (c) 1984 Springer-Verlag New York Inc.)
