BPA in dust bunnies?
Dust is defined as fine, dry particles of matter, present everywhere where matter is present. From the cosmic dust of the universe to the dust that lingers on household surfaces, it is a part of our everyday lives.
Other than being a common annoyance, dust is also a topic of research for some scientists. A current focus is the environmental contaminants in household dust: what types are present, how they got there and how they move around. These factors can provide important information about what exactly is in these particles, and is especially good to know for babies and toddlers who are more likely to put items in their mouth.
One of the contaminants tested is bisphenol A (BPA), which is primarily used to make polycarbonate plastic and epoxy resins. Clear and highly shatter-resistant, polycarbonate is used in common consumer products such as bicycle helmets, sunglass lenses and CDs. Epoxy resins are tough, durable materials that excel as protective coatings used to prevent corrosion of metal products.
Recent studies revealed BPA in dust samples from 15 countries in North America, South America, Europe, Asia and the Middle East. The levels found were all very low, in the range of one part per million.
Researchers also estimated the levels of human exposure to BPA from dust, and found that levels were about 5,000 times below the safe intake limit set by U.S. government agencies. Remember, FDA answers the question “Is BPA Safe?” with an unambiguous answer – “Yes.” In other words, the next time you’re vacuuming those dust bunnies from under the couch, there’s no need to worry about BPA.
