Many naturally occurring, man-made substances present at low concentrations can harm human health and ecosystems. For better protection, risks need to be assessed. An important step in risk assessment is to identify and quantify toxic substances present in our environment, and determine the threshold concentrations below which exposure is not expected to cause adverse effects.
This talk will assess the environmental fate and risks of persistent toxic substances, e.g. perfluoroalkyl substances, on local wildlife such as the Indo-Pacific humpbacked dolphins and water birds. In addition, the latest research on marine toxins will be presented.
