Below the Surface
Casual chats between an Austrian and Australian on environmental topics that usually don't get talked about openly.
Hosts Gunnar Haid and James Hammond set out to provide a light-hearted and thought-provoking look into Contaminated Land, Resource Recovery, Ecology and general environmental issues in Australia, in particular NSW. They use their experience and industry connections to talk about subjects that, at least in their opinion, don't get talked about enough or not in the right context. Join them for a chuckle and some unique perspectives.

#38 The Bioavailability
How much of any given contaminant is actually taken up into human bodies?
If we think about it, that is one of the single most important things to consider as an environmental consultant when reporting on a site's contamination status, yet it is not something that is very often done. Gunnar and James are yet again soaring with an industry eagle as they set out to get better at that very aspect of consulting.
They chat with Dr Albert Juhasz, a Research Professor at the Future Industries Institute, internationally recognised for cross-disciplinary research on contaminant bioavailability and human health exposure. He has led development of one of the world’s largest contaminant bioavailability databases and advanced in vitro methods now applied at more than 100 contaminated sites across Australia.
His work has informed national and international exposure assessment policy, including the ASC NEPM and EnHealth Guidelines, and influenced regulatory guidance in the US, Canada and New Zealand. Albert is a senior journal editor, WHO consultant, contaminated-site auditor adviser, and a highly cited researcher (H-index 37).
