Probably, idk if there are such specific studies. The thermal sensitive layer contains very large amounts of BPA in a dusty form that will easily contaminate your hands. BPA is a major endocrine disruptor. They might say BPA-free, which would be technically correct, but that just means they'll use a near identical BPA variant that isn't proven to be an endocrine disruptor yet. Handle with care, wash your hands, don't put them in the kitchen.
