In the first part of the study, fish (n = 12) were exposed for 1 week to one of the two concentrations of Cd (CdCl₂ · 2H₂O; Sigma, Milan, Italy): a sublethal concentration (2.26 mg/L; n = 6) or a calculated maximum acceptable toxicant (MAT) concentration ( mg/L; n = 6), which were both less than the 96-hr LC₅₀ (lethal median concentration) value of mg/L (Giusi et al. 2004) and the 96-hr LC₅₀ value of mg/L quickflirt obtained in the white sea bass, Lates calcarifer (Thophon et al. 2003). This contaminant was prepared by dissolving CdCl₂ · 2H₂O in appropriate volumes of seawater. Other fish (n = 12) were exposed for the same length of time to two concentrations of endosulfan (Sigma): a sublethal concentration (0.2 ?g/L; n = 6) and a calculated MAT concentration (1.3 ?g/L; n = 6) that were both less than the 96-hr LC₅₀ value of 3.30 ?g/L (Giusi et al. 2004), and the 96-hr LC₅₀ value varying between 1.4 and 1.5 ?g/L for freshwater fish (Johnson and Finley 1980), sublethal and MAT concentrations that fall within the ranges reported in surface waters (0.039–0.205 ?g/L) and after runoff water events (0.01–1.3 ?g/L) from agricultural areas, respectively (Naqvi and Vaishnavi 1993).Read More
