(FACID-09) O bisfenol A (BPA) é utilizado na obtenção de policarbonatos, uma espécie de polímero empregado na fabricação de cd’s, garrafas transparentes, mamadeiras e outros utensílios domésticos. Estudos recentes demonstraram que o BPA pode causar deformações em células cerebrais de fetos e recém-nascidos, além de ser responsável pela formação de tumores na próstata e câncer de mama em cobaias, devido à sua semelhança química com o estrogênio. A lixiviação do BPA em água aumenta com o aumento da temperatura. Se, a 25 ºC, a massa de BPA dissolvido em uma mamadeira é 0,32 nanogramas e, a 60 ºC, aumenta para 23,12 nanogramas, o número de moléculas de bisfenol A desprendidas da mamadeira durante o seu aquecimento será: Dado: 1 ng = 1 ∙ 10-9 g
