24 September 2021Industrial chemical PFBA does not accumulate excessively in lungs and kidneys
A 2013 study by Pérez et al. reported a very high accumulation of the industrial chemical perfluorobutanoic acid (PFBA) in human lungs and kidneys. The German Federal Institute for Risk Assessment (BfR) checked these results using a more precise quantification method. The result: Only one sample contained a quantifiable PFBA value of 0.17 nanograms (ng) per gram (g) of lung tissue. The BfR comes to the conclusion that PFBA is very unlikely to accumulate strongly in human lung and kidney tissue. This is supported by the short half-life of PFBA in the blood, which was determined in another study.
