Toxic foam: NZ seeing 'tip of iceberg'

A Queensland environmental medicine specialist says New Zealand is just seeing the tip of the iceberg when it comes to problems associated with toxic foam. The government now admits it's "essential" to use a new, wide-ranging test to assess the long term health impacts of firefighting foam contamination. Despite this, it isn't using this test at all. Andrew Jeremijenko spoke with Phil Pennington about the long term health risk of PFOS and PFOA.
