Abstract EN
Adult freshwater snails Melanoides tuberculata (Gastropod, Thiaridae) 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.
The LC50 values for the 96-hour exposures to Cu, Cd, Zn, Pb, Ni, Fe, Al, and Mn were 0.14, 1.49, 3.90, 6.82, 8.46, 8.49, 68.23, and 45.59 mg L−1, respectively.
Cu was the most toxic metal to M.
tuberculata, followed by Cd, Zn, Pb, Ni, Fe, Mn, and Al (Cu > Cd > Zn > Pb > Ni > Fe > Mn > Al).
Metals bioconcentration in M.
tuberculata increases with exposure to increasing concentrations and Cu has the highest accumulation (concentration factor) in the soft tissues.
A comparison of LC50 values for metals for this species with those for other freshwater gastropods reveals that M.
tuberculata is equally sensitive to metals.
