1. Conversely, some micronutrients like P and Zn may have limited availability in oysters at some sites in Richmond River and contribute to lower survival of SRO. This evidence suggests that it would be useful to develop ecotoxicology guidelines that apply to metal mixtures rather than single elements. Furthermore, evidence from this study suggests that a strategy for mitigating lowlevel metal contamination in the Richmond River estuary is required to improve the health of natural oyster populations and the potential for aquaculture;other stressors)
