Key activities to support communities affected by PFAS

• Provide health “standards” for PFAS exposure.
• Ensure potential adverse human health effects are

better understood through an epidemiological study.

• Provide access to blood tests for PFAS for those who

want them.

• Ensure access to health services that are able to

support people who are stressed or anxious as a result

• f PFAS contamination and the uncertainty about

health effects.

• Before June 2016 there were no Australian human

health standards for PFOS and PFOA.

• In June 2016, enHealth made recommendations on

interim standards that could guide the Human Health Risk Assessments at contaminated sites.

• Standards were needed so that authorities could

provide advice to communities while more work was undertaken. Human health standards for PFOS and PFOA

• enHealth looked at the standards developed by
• verseas regulatory agencies, and the methodology

these agencies used.

• enHealth recommended that Australia adopt the

approach used in Europe because the approach is the same as used in Australia to set standards for chemicals.

• The method used by the European agency is the

most widely adopted internationally. What did enHealth recommend?

• In August 2016, the enHealth interim standards

were independently reviewed by an expert in chemical regulation and toxicology.

• The review found enHealth’s decision was

appropriate and is protective of public health. The enHealth standards were independently reviewed

FSANZ

Food Standards Australia New Zealand

Main objectives for FSANZ

In developing or reviewing food regulatory measures, FSANZ focuses on…

Protection of public health and safety. Provision of adequate information to consumers. Prevention of misleading or deceptive conduct.

Food Standards Australia New Zealand Act 1991

FSANZ is now assessing PFAS

• FSANZ is working on final health based guidance

values that will replace the interim ones established by enHealth.

• FSANZ’s work will look at potential exposure to

PFAS from food at contaminated sites and the general food supply.

Further research is critical

• The current health advice for PFAS exposure is:
• There is currently no c

consisten ent eviden ence that exposure to PFOS and PFOA causes adverse human health effects. Because these chemicals persist in humans and the environment, enHealth recommends that human exposure to these chemicals is minimised as a precaution”

• What this means is that the human studies to date have not

consistently shown a clear link between poor health and PFAS exposure.

• We need further studies to see what the health issues are in the

community and if there are any links to PFAS exposure.

• At the moment the uncertainty is causing stress and anxiety, which is

a significant concern to health authorities.

An Epidemiological Study for Williamtown and Oakey

• Epidemiological studies look for relationships

between a potential risk to health and any unusual patterns of disease or adverse health effects.

• The National Centre for Epidemiology and Population

Health (NCEPH) will conduct a study in the Williamtown and Oakey communities.

• Participation in the study will be purely voluntary.
• Community consultation will be an important input

into the study design.

International Agency for Research on Cancer

• IARC identifies factors that can increase the risk of human cancer,

including chemicals, complex mixtures, occupational exposures, physical agents, biological agents, and lifestyle factors.

• Group 1: carcinogenic to humans: tobacco smoke, alcohol, processed meat,

mustard gas, asbestos, arsenic;

• Group 2A: probably carcinogenic to humans: DDT, glyphosate (Round-up),

red meat;

• Group 2B: possibly carcinogenic to humans: PFOA, petrol, talc-based body

powder, chloroform;

• Group 3: not classifiable as to its carcinogenicity to humans: tea, coffee,

paracetamol

• Group 4: probably not carcinogenic to humans: caprolactam

Should you get a blood test?

• Blood tests cannot determine whether any medical

condition is caused by PFOS or PFOA.

• Blood tests do not inform the clinical advice your

doctor can give you – particularly in relation to diagnosis, treatment or prognosis.

• Blood tests are, however, important for the

epidemiology study.

11

Voluntary blood testing for Williamtown and Oakey

• Blood tests will be made available, free of charge, to

those who have lived or worked in the Investigation Areas.

• A pre- and post-test discussion with your GP will

ensure you are given all the relevant information about the test and ensure you understand that the results will not be able to be used by your doctor to provide medical advice.

• Ideally, people who volunteer for a blood test will also

join the epidemiological study.

12

Additional counselling services will be available

• For some, the biggest risk of becoming unwell from

PFAS contamination will be through stress and worry.

• We would encourage anyone who is feeling anxious or

worried about the contamination to seek advice from their GP and take advantage of the counselling services available.
