PFAS cocktails is not something we'd recommend [SWOP NEWS]

Research has revealed that mixtures of PFAS compounds are more harmful than individual chemicals, posing significant health risks. Here are the key points:
PFAS are toxic chemicals known as "Forever Chemicals" that have been used since the 1950s because of their non-stick behaviour. They are often part of plastic manufacturing
PFAS Mixtures Toxicity:
Studies have shown that mixtures of PFAS compounds are more harmful than individual chemicals, indicating a greater risk to human health than previously recognized. This is because regulatory bodies often evaluate these chemicals in isolation, potentially leading to an underestimation of their health hazards.
Additive Toxicity:
The study found that the toxicity of PFAS compounds adds up when combined, rather than exhibiting synergistic effects. This means that the combined toxicity of PFAS compounds can be alarming, even if their concentrations fall below the EPA's drinking water threshold for each individual substance.
Common PFAS Compounds:
PFOA and PFOS are among the most prevalent and hazardous PFAS chemicals, frequently detected in contaminated human blood and drinking water. These compounds are linked to various severe health issues, including cancer, birth defects, and compromised immune function.
Biosolids Contamination:
PFAS compounds are also found in sewage sludge, which is often used as a low-cost fertilizer on agricultural land. This biosolid can contaminate water sources and food supplies, posing additional health risks.
Regulatory Gaps:
Despite the known risks, there are few regulatory or guidance limits for PFAS in surface water that may affect fish and consumers of fish. This highlights the need for comprehensive regulatory standards to address PFAS contamination.
