Borthwick, Patrick W. and James M. Patrick. 1982. Use of Aquatic Toxicology and Quantitative Chemistry to Estimate Environmental Deactivation of Marine-Grade Creosote in Seawater. Environ. Toxicol. Chem. 1(4):281-288. (ERL,GB 421).
The acute toxicity of marine-grade creosote, expressed as the 96-h LC50, is 0.018 mg/l for mysids (Mysidopsis bahia, Molenock), .024 mg/l for pink shrimp (Penaeus durorum, Burkenroad), and 0.72 mg/l for sheepshead minnows (Cyprinodon variegatus, Lacepede). The 96-h EC50 (shell deposition) for Eastern oysters (Crassostrea virginica, Gmelin) is 0.71 mg/l. Mysid bioassays and chemical analyses estimate the half-life (<1 week) for marine-grade creosote in seawater. |
