Figure 1. This image shows how the shirts were hanged indoors and exposed to high concentrations of BP-3 and then how those same shirts were used by participants of the study. Figure taken from Glenn et al. 2017.
If you ask someone if they think their shirt is deadly, the most probable answer will be no. No one thinks that a simple shirt could be a danger to your health in any type of way. A study done on the dermal uptake of Benzophenone-3 from clothing was conducted to see how much of a burden this endocrine disruptor would be once it has gotten into your home and onto your clothing via plastics and sunscreens. The study describes how cotton shirts were exposed constantly to BP-3 for 32 days at high concentrations with the final concentration being 4.4 μg/m³. The participants then wore the shirts for three hours and had urine samples collected and analyzed to reveal that the sum of BP-3 excreted were sums of 12, 9.9 and 82 μg for the different participants. This study mainly implies that the applications of cosmetics and other care products are not the only issue but that BP-3 in our indoor air could cause a greater burden to our human health as well.
