Heavy Metal Exposures on Freshwater Snail Pomacea insularum: Understanding Its Biomonitoring Potentials

The present investigation focused on the toxicity test of cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn), utilizing two groups juvenile adult apple snail Pomacea insularum (Gastropod, Thiaridae) with mortality as endpoint. For snails, median lethal concentrations (LC50) values based 48 72 h decreased in following order: Cu < Ni Pb Cd Zn. LC50 mussel was more susceptible to than other four metal exposures, although juveniles were sensitive adults because former had lower latter. This study provided essential baseline information for five toxicities using P. a organism, allowing comparisons acute sensitivity this species metals. In conclusion, demonstrated that biomonitor model organism assess heavy risk factors severe toxicities. A comparison these metals those freshwater gastropods revealed equally Therefore, can be recommended good ecosystems.
