New information on per- and polyfluoroalkyl substances (PFAS) was released today by the Australian Bureau of Statistics (ABS). 

James Eynstone-Hinkins, ABS head of health statistics said: ‘This data will help to create a national baseline for levels of PFAS in the Australian population. The dataset will enable future monitoring and support further research into PFAS and the potential impacts of these chemicals on human health,’ 

11 types of PFAS were tested for people aged 12 years and over in the National Health Measures Survey. Three types of PFAS were detected in the blood of over 85 per cent of the population, while six types were detected in less than 10 per cent of people. The remaining 2 types of PFAS had detection rates between 15% and 45%. 

‘PFAS levels varied, but in general people who were older had higher PFAS levels. This was in line with expectations as there have been changes in the population’s exposure to PFAS over time,’ Mr. Eynstone-Hinkins said.

‘PFAS levels were also generally higher for males than for females.’

The levels for the three most prevalent PFAS analysed (PFOS. PFHxS, PFOA) are lower in Australia than those reported from previous studies in the United States, Canada and Europe. The timeframe for each of these studies varied, potentially impacting the comparability of recorded PFAS levels.

Media notes

  • When reporting ABS data you must attribute the Australian Bureau of Statistics (or the ABS) as the source.
  • The ABS’ National Health Measures Survey (NHMS) 2022–24 was a voluntary survey. Blood and urine samples were tested for biomarkers of chronic disease, nutrient levels and 11 types of PFAS chemicals.
  • You can find more information on the collection and testing of samples in National Health Measures Survey 2022–24 methodology.
  • A non-detect result does not mean that a person has no PFAS in their blood, just that the level was too low to be accurately measured. It is expected that everyone has had some level of exposure to PFAS.
  • International studies were undertaken at different times and comparing these results should be done with caution. As is the case in Australia, PFAS exposure levels have been reported to be declining in the last two decades in North America and Europe.
