An article published by Chemical Watch on September 6, 2017 informed about the results of urine analyses obtained within the biomonitoring campaign “Detox Me Action Kit” run by the Silent Spring Institute, U.S.. In this campaign, participants were asked to ship in urine samples for subsequent analysis.

Initial results revealed the presence of at least two chemicals in all of the roughly 150 participants analyzed so far. One of these chemicals was the preservative methyl paraben (CAS 99-76-3), detected in every participant. Further, compared to the general U.S. population, campaign participants had lower levels of bisphenol A (BPA, CAS 80-05-7), but higher levels of bisphenol F (BPF, CAS 620-92-8). The Silent Spring Institute called this finding “troubling.” According to an in-house survey, 85% of the participants said that they “avoid buying products with BPA on the label.” Therefore, lower levels of BPA are “not surprising,” but do show that ‘BPA-free’ products may increase people’s exposure to other bisphenols which are suspected to be similarly harmful (FPF reported).
