This study investigated the toxicity of three major pollutants, copper, lead, zinc and a combination of these, on Haliotis iris (abalone) and Evechinus chloroticus (sea urchin), two endemic species of high ecological, cultural and commercial importance (MacDiarmid 2007, Morrison et al. 2009). Responses of H. iris and E. chloroticus to pollutants have never been investigated. Both species are endemic but also distantly related to other abalone and sea urchin species (Degnan et al. 2006, Gillard et al.2014). Therefore their sensitivity to pollutants may be different from their Australian counterparts and they might not be protected by the current WQC.
