✦ Synopsis
The acute toxicity of a range of organic reference chemicals has been evaluated using the ( ) embryo-larval stages of the marine polychaete Platynereis dumerilii Audouin and Milne-Edwards . After exposure under static conditions at 20 " 1ЊC, EC values were calculated based upon reductions in 50 normal embryo development. After exposure of 7 day old larvae under the same conditions, LC values 50 were calculated based on larval survival. The embryo development 48 h EC and larval 48 h LC 50 50
values were, respectively, 6.39 and 8.94 mg L y1 for 3,4-dichloroaniline, 122 and 104 mg L y1 for phenol, 23.6 and 14.4 mg L y1 for 4-chlorophenol, 4.24 and 3.20 mg L y1 for 3,5-dichlorophenol, 2.55 and 4.24
for 2,4,5-trichlorophenol, and 0.52 and 1.33 mg L for sodium pentachlorophenate all based ) on nominal values . Comparison of these data with other published values suggest that, for these reference toxicants, the embryo-larval stages of P. dumerilii are of similar sensitivity to the early life stages of several other marine invertebrate species. These observations add to the refinement of a suite of bioassay techniques using P. dumerilii which, linked to previous studies, can be used to evaluate the developmental toxicity, cytotoxicity, and genotoxicity of marine contaminants.
