Chemical Watch - Silent Spring study reveals higher than expected BPF levels

September 7, 2017

Excerpt: "Urine analysis for a campaign run by the Silent Spring Institute has revealed higher than expected levels of bisphenol F, an alternative to BPA.

The US institute is running a crowdsourced campaign called Detox Me, with more than 300 people having signed up so far. It sends out urine test kits to detect the presence of ten common environmental chemicals. Each participant then receives a report listing their urine analysis results.

Initial results suggest that participants have lower levels of BPA than the US population in general, but higher levels of BPF.

The BPF finding is "troubling", says the institute. About 85% of action kit users deliberately avoid buying products known to contain BPA. However, by choosing 'BPA-free', they may be buying products containing substitutes like BPF, it suggests.

The results for BPF may reflect rising levels in the general public, with the most recent nationwide measurements for the US Centers for Disease Control and Prevention taken several years ago, it adds.

Studies suggest that BPF, and the commonly used BPS, may cause similar health effects to BPA. 

The Swedish Chemicals Agency recently suggested that BPF and BPS should be the focus of regulatory action, together with four other related chemicals. 

The EU has already initiated risk management option analyses (RMOA) under REACH for the chemicals.

Although Detox Me users report avoiding products containing parabens, they all had at least one in their sample and more than 60% had three or four.

Overall, participants have lower levels of target chemicals than the US population as a whole, according to the institute."
