PFAS are often called "forever chemicals" because they break down very slowly in the environment and can accumulate in the human body over time.
It's important to note that studying the effects of everyday PFAS exposure is challenging. Many factors can influence health outcomes, and it's difficult to isolate the specific impact of PFAS in the general population. However, some studies have suggested potential health concerns:
Immune System Effects
There's evidence that PFAS exposure may affect the immune system, potentially leading to reduced vaccine efficacy in children and increased susceptibility to certain infections.
Hormonal Disruption
PFAS may interfere with hormone function, particularly thyroid hormones, which play crucial roles in metabolism and development.
Cholesterol Levels
Some research has indicated a possible link between PFAS exposure and higher cholesterol levels, though the long-term implications of this are not yet clear.
Liver Function
There's some evidence suggesting that PFAS exposure could affect liver function, though more research is needed to understand the extent and mechanisms of this impact.
Developmental Concerns
Some studies have raised questions about potential developmental effects, including possible impacts on birth weight and early childhood growth.
It's crucial to emphasise that while these potential effects have been observed in some studies, the research on everyday PFAS exposure is still evolving. Many of these findings are based on correlations, and more research is needed to establish clear causal relationships.
Moreover, regulatory bodies and health organisations worldwide are increasingly focusing on PFAS. Many countries are implementing stricter regulations on PFAS use and are working to reduce environmental contamination.
For individuals concerned about PFAS exposure, there are some steps that can be taken:
-
Use 100% PFAS free non-stick cookware or stainless steel or cast iron cookware instead of traditional non-stick pans.
-
Choose PFAS-free personal care products and cosmetics.
-
Avoid stain-resistant treatments on furniture and carpets.
While it's nearly impossible to completely avoid PFAS in modern life, being aware and making informed choices can help reduce exposure, especially within the home.
