The effects of various biocides, as used in drilling muds for exploratory drilling for oil offshore, were determined by comparing macrobenthic communities that developed from planktonic larvae in treated and untreated aquaria. Surflo(R)-B33 and Aldacide(R) were tested simultaneously. Harvest at seven weeks yielded 1,941 animals, representing 37 species of 6 phyla. The effects of Surflo-B33 (25% dichlorophenol and other chlorophenols) on these communities were similar to those of pentachlorophenol, a biocide known to be toxic to many aquatic organisms.
