Résumé

Safe concentrations (SCs) and EC50s of fluoride ion (F-) for five species of aquatic insect larvae, Chimarra marginata, Hydropsyche bulbifera, H. exocellata, H. lobata, and H. pellucidula, are estimated from short-term toxicity bioassays using the multifactor probit analysis (MPA) software on sublethal data. The sublethal effect is defined as ‘net larva migration.’ The 24, 48, 72, and 96-h EC50s (mg F-/L) were 178.06, 63.90, 45.41, and 38.28 for C. marginata; 90.06, 36.20, 26.71, and 22.95 for H. bulbifera; 122.64, 42.45, 29.80, and 24.97 for H. exocellata; 238.50, 76.22, 52.12, and 43.09 for H. lobata; and 185.05, 53.74, 35.58, and 28.96 for H. pellucidula. SC values (or 8760-h EC0.01s) were 1.79 for C. marginata, 0.73 for H. bulbifera, 0.56 for H. exocellata, 1.18 for H. lobata, and 0.39 for H. pellucidula. Thus, C. marginata and H. lobata appears to be less sensitive species to fluoride toxicity during short-term and long-term exposures. This difference in sensitivity to fluoride among test species is not dependent upon the body size of net-spinning caddisfly larvae; Pearson correlation analysis between estimated SCs and larva dry weights was not significant (P>0.05). On the other hand, SCs calculated for test species are lower than those proposed for other freshwater and marine animals. It is concluded that the multifactor probit analysis of sublethal acute toxicity data can be a valuable methodology in environmental toxicology to estimate accurate safe concentrations of chemical compounds for aquatic organisms.
