AbstractChronic toxicity, growth and reproduction were measured in the freshwater gastropod Lymnaea stagnalis exposed to waterborne bis(tri-n-butyltin) oxide (TBTO) over a range of four nominal concentrations (0-10 μg TBT l-1). Egg development was completely inhibited at 10 μg TBT l-1, whilst abnormal embryonic development was observed at 1 μg TBT l-1. For the solvent control and the 0.01 μg TBT l-1treatment group, normal development of L. stagnalis was observed. Survivorship of hatchlings was significantly reduced by TBT at 1 μg l-1 while inhibition of shell growth of L. stagnalis was also observed at this concentration. The data were used to determine intrinsic growth rates (r) using two theoretical approaches (the Euler-Lotka equation and a Leslie Matrix). Both approaches showed that survival, fecundity and population growth rate were reduced at 1 μg TBT l-1. Interestingly, at 0.01 μg TBT l-1 snails showed a higher fecundity and growth rate than in the solvent control. The TBT concentration at which the r would equal zero (ECr0) and the population NOEC (No Observed Effect Concentration) were estimated. The population NOEC was defined as either the lower 95% confidence or lower 95% pointwise percentile limit of the ECr0. Values obtained using the two different approaches were similar and thus a geometric mean was calculated to obtain a final representative population NOEC value for L. stagnalis of 2745 ng TBT l-1. The present data together with chronic toxicity TBT data for freshwater organisms, obtained from peer-reviewed literature, were used to construct a species sensitivity distribution (SSD). A predicted no effect concentration was then derived from the SSD (hazardous concentration at 5%, i.e., HC5 or 95% protection level). This SSD was compared with the SSD derived from saltwater species datasets. The HC5 value for saltwater species (3.55 ng TBT l-1; lower confidence limit: 1.93 ng TBT l-1) was significantly lower than that for freshwater species (30.13 ng TBT l-1; lower confidence limit: 9.23 ng TBT l-1), indicating that saltwater species are probably more susceptible to TBT than their freshwater counterparts. © 2006 Elsevier Ltd.
