Bisphenol-A is a compound used as a building block of certain types of plastics, including polycarbonates. The chemical, dubbed BPA for short, has been largely eliminated from consumer products such as baby bottles and water bottles. However, BPA has another less obvious use in thermal printers and 'carbonless copy paper.' That means the compound may be found in some fax machines, as well as in store cash register receipts. We'll talk about it and whether it matters.
