2024 May: PFAS Chemicals in Pesticides. - Australian Pesticides Map

PFAS chemicals in Pesticides May 2024

This post wants to alert readers about the possible PFAS contamination of commonly used pesticides in Australia. It will be updated as new information comes to hand.

A major source of PFAS contamination of pesticides is likely to come from fluorinated HDPE containers. The US EPA appears to be trying to grapple with this problem, but what about Australia?

https://www.epa.gov/system/files/documents/2022-09/EPA%20PFAS%20Container%20Leaching%20Study%2008122022_0.pdf

The other source of PFAS contamination of pesticides would be in the manufacturing processes. PFAS or related compounds are included in 70% of pesticides introduced to the global market from 2015 to 2020, according to https://www.sciencedirect.com/science/article/abs/pii/S0269749121018972?via%3Dihub published in January 2022.

Many of these pesticides are registered for use in Australia, some with common applications. Many users of the chemicals will be unaware of the potential PFAS contamination issues regarding a range of pesticides that they may use.

These could include commonly used pesticides such as: Imidacloprid, Bifenthrin, Piperonyl Butoxide, Abamectin, Fipronil, Diflufenican, Trifluralin, Flutriafol, Indoxacarb and Fluroxypur.

The table below was sourced from 8 references where PFAS contamination of pesticides was published. In the list below ref refers to the reference at the bottom of the list. Pubris refers to the APVMA database which users can search for registered pesticides and ingredients in Australia. Results refer to how many products have that particular pesticide listed under Pubcris.

The most listed products include the following pesticides: Imidacloprid, Bifenthrin, Piperonyl Butoxide, Abamectin, Fipronil, Diflufenican, Trifluralin, Flutriafol, Indoxacarb and Fluroxypur.

As new information comes to hand some of the list may be deleted. Other pesticides are also likely to be added to the list as well.
