In this study we test the sensitivity of three sizes of golden mussel ( Limnoperna fortunei ), an introduced species in Argentina, to a 96-h exposure to Cd 2 + , Cr 6 + , and Ni 2 + . We also analysed the relative sensitivity of L. fortunei compared to other freshwater bivalve equivalent sensitivity data. The ANOVA results showed that both factors, heavy metal and size, had significant effects ( p = 0.0013 and p = 0.0091, respectively) on the mortality of the golden mussel. Tukey’s test showed significant differences for Cr 6 + treatment and the smallest size class (7 mm ± 1 ). The relative sensitivity analysis showed that LC 50 values for the smallest size class of L. fortunei exposed to Ni 2 + and Cd 2 + were in the low range, with values of 11.40 mg/L and 12.65 mg/L, respectively. In the case of Cr 6 + (1.66 mg/L), its LC 50 was in the medium-low range of the freshwater bivalve sensitivity distribution.
