how to understand PFAS measurements
How do Australia rate against other countries for exposure protection?
Australia mainly uses measurements expressed in micrograms (μg), nanograms (ng) and parts per trillion (ppt).
A concentration of part per million can correspond to 1 part material per 1 million parts regardless of whether it is a gas, liquid or solid.
Because PFAS substances have been proven to be dangerous in such tiny amounts is why these small fractions are used and why various analogies can also be used to visualise the concentrations as a comparison.
While the Australian Government, EPA’s and industries can test for at least 28 PFAS substances, they only need to be compliant with just 3.

The Australian Government is overseeing regulatory agencies and Commonwealth entities with obligations under food safe acts to allow highly contaminated meat to be sold into both the domestic and export market for human consumption.
We know of cattle that had PFAS blood serum levels around 1500ng/ml (1,500000 ppt) which the Australian Government has declared is fit for human consumption. Who is eating our contaminated meat?
Other countries are introducing more stringent requirements to monitor, clean up and reduce PFAS exposures to their citizens because their governments deem PFAS compounds unsafe, a hazard and a significant health burden to their population.
Yet the Australia Government and State EPAs do not see the same PFAS compounds as a health burden in Australia nor treat PFAS as hazardous. Worst, our government are not even prepared to protect our agricultural markets from PFAS contamination.
