Signal PFAS found in human and animal blood worldwide

Summary

The report states that many PFAS chemicals have been detected in the blood of people and animals worldwide. It classes PFAS as emerging contaminants alongside pharmaceuticals, industrial pollutants and nanomaterials. The finding is presented as an example of pollutants spreading across borders and building up in living organisms. The report explains that long exposure to pollutants at low concentrations can still result in bioaccumulation and is a risk factor for many diseases. Much is still unknown about the effects of long-term exposure to complex mixtures. Over the longer term, the report expects new mixtures of chemicals, among them endocrine disruptors, could create new health challenges.
