Abstract EN
Adults of freshwater ostracod Stenocypris major (Crustacea, Candonidae) were exposed for a four-day period in laboratory conditions to a range of copper (Cu), cadmium (Cd), zinc (Zn), lead (Pb), nickel (Ni), iron (Fe), aluminium (Al), and manganese (Mn) concentrations.
Mortality was assessed, and median lethal times (LT50) and concentrations (LC50) were calculated.
LT50 and LC50 increased with the decrease in mean exposure concentrations and times, respectively, for all metals.
LC50s for 96 hours for Cu, Cd, Zn, Pb, Ni, Fe, Al, and Mn were 25.2, 13.1, 1189.8, 526.2, 19743.7, 278.9, 3101.9, and 510.2 μg/L, respectively.
Metals bioconcentration in S.
major increases with exposure to increasing concentrations, and Cd was the most toxic to S.
major, followed by Cu, Fe, Mn, Pb, Zn, Al, and Ni (Cd>Cu>Fe>Mn>Pb>Zn>Al>Ni).
Comparison of LC50 values for metals for this species with those for other freshwater crustacean reveals that S.
major is equally or more sensitive to metals than most other tested crustacean.
