PFAS Exposure & Environmental Health

NATUROPATHIC SERVICES · NORFOLK ISLAND

PFAS are everywhere. And most people have no idea they've been exposed.

Per- and polyfluoroalkyl substances — PFAS — are a group of over 12,000 synthetic chemicals that have been used in industrial and consumer products since the 1940s. They don't break down in the environment, and they don't break down in the body. That's where the problem begins.

Where PFAS exposure comes from

Exposure is far more common than most people realise. Sources include:

  • Contaminated drinking water — particularly near airports, military bases, and industrial sites where aqueous film-forming foam (AFFF) has been used

  • Non-stick cookware (PTFE/Teflon) and food packaging including microwave popcorn bags, fast food wrappers, and grease-resistant containers

  • Stain-resistant treatments on carpets, furniture, and clothing

  • Personal care products including some waterproof mascaras, foundations, and sunscreens

  • Firefighting foam

  • Contaminated soil and locally grown produce in affected areas

PFAS accumulate in the body over time. A single exposure is rarely the issue — it's the cumulative, ongoing burden from multiple sources across years or decades.

How PFAS affect health

The research on PFAS and human health is substantial and growing. Documented health associations include:

  • Thyroid disruption — PFAS interfere with thyroid hormone production and transport, contributing to hypothyroidism, fatigue, weight changes, and hormonal dysregulation

  • Immune suppression — PFAS have been shown to reduce vaccine efficacy and impair immune response, particularly in children

  • Hormonal disruption — PFAS are endocrine disruptors, interfering with oestrogen, testosterone, and adrenal hormone signalling

  • Reproductive and fertility impacts — including reduced sperm quality, altered menstrual cycles, and associations with endometriosis and PCOS

  • Increased cancer risk — particularly kidney and testicular cancer, with associations also noted for breast and ovarian cancers

  • Liver stress and lipid dysregulation — elevated cholesterol and liver enzyme abnormalities are commonly seen in high-exposure populations

  • Gut microbiome disruption — emerging research links PFAS exposure to reduced microbial diversity and altered gut barrier integrity

Naturopathic support for PFAS exposure

There is currently no established medical protocol for PFAS detoxification — and anyone claiming to offer a quick fix should be approached with scepticism. What naturopathic support can offer is meaningful: reducing ongoing exposure where possible, supporting the body's natural detoxification pathways, addressing the downstream health effects of PFAS burden, and monitoring relevant markers over time.

Support may include:

  • Identifying and reducing ongoing sources of exposure

  • Liver and detoxification pathway support

  • Gut integrity and microbiome support — particularly relevant given PFAS impacts on the intestinal barrier

  • Thyroid and hormonal monitoring and support

  • Immune system support

  • Targeted nutritional and antioxidant support to reduce oxidative burden

  • Functional testing to assess relevant health markers

This support is available in person on Norfolk Island and via telehealth worldwide.
