This paper reports the results of toxicity tests conducted using Anguilla anguilla under three different water temperature (15, 22 and 29°C) and two hardness regimes (250 and > 600 ppm CaCO3). The 96-h LC50 increased in the experimental medium (p<0.05) by an order of magnitude from 0.32 to 0.45 mg/L between 15 and 29°C. However in the natural medium it is similar (p>0.05)(0.54 to 0.55 mg/L) for these same temperatures. The toxicity of Lindane on eels increased when the water hardness decreased. The 24, 48, 72 and 96-h LC50 for this fish in both media is less at 15°C (96-h LC50= 0.32 and 0.55 mg/L) than at 29°C (96-h LC50= 0.45 and 0.55 mg/L).These results suggest that the toxicity of Lindane presents a negative temperature coefficient.
