1.8 THESIS RESEARCH
1.8.1 AIMS
The effects of metals were investigated for E. chloroticus across multiple life stages using laboratory experiments with realistic exposure scenarios. A special emphasis was given to early life stages and carry-over and/or latent effects across the larval and juvenile development (Figure 1.1). In addition, the effect of multiple pollutants,multiple stressors (metal and salinity) and trophic interactions were evaluated.
1.8.2 THESIS STRUCTURE
In Chapter 2, standard short-term bioassays (72 h) were performed on the embryo/early larval stages of E. chloroticus and also the endemic abalone Haliotis iris, for comparison. These assays evaluated the toxicity of three major pollutants(copper, lead and zinc) alone and in combination, on these species. This provided a first measure of metal toxicity on theses species.
