Introduction

We are very fortunate to be living so close to these dolphins. However many people are not aware of their presence in the Port River and surrounding areas or of the threat to their environment and their survival.

"Bottlenose dolphins in South Australia's Gulf St Vincent have been recorded with the highest mercury levels in the world, with dangerous levels of the now banned but long-lived chemical PCB and the heavy metal lead. High levels of cadmium and lead pollution have also been recorded in the food chain in Spencer Gulf in South Australia".
