Abstract
This study evaluated the in vivo toxicity of four kinds of oil dispersants to Cynoglossus semilaevis, in acute exposures of 24, 48, 72, and 96 h through mortality. The 24 h LC50 of RS-1, HH, GM-1, and FK were 17.0793, 4.6957, 3.2758, and 4.7510 mg/L, respectively. The 48 h LC50 were 16.0173, 3.7251, 2.2135, and 2.5568 mg/L. The 72 h LC50 were 14.6422, 2.9266, 1.9983, and 1.8877 mg/L. The 96 h LC50 were 13.7879, 2.3060, 1.4391, and 1.5962 mg/L. The decreasing order of toxicity was GM-1 > HH > FK > RS-1. Compared with the grading table of toxicity of chemical dispersants, four kinds of oil dispersants were highly toxic.
