O amianto é composto por silicato de mineral fibroso de composição química diversa. Quando se inala, as fibras de amianto fixam-se profundamente nos pulmões, causando cicatrizes. A inalação de amianto pode também produzir o espessamento dos dois folhetos da membrana que reveste os pulmões (a pleura). As pessoas que trabalham com o amianto correm o risco de sofrer doenças pulmonares. Os operários que trabalham na demolição de construções com isolamento de amianto também correm risco, embora menor. Quanto mais tempo um indivíduo estiver exposto às fibras de amianto, maior é o risco de contrair uma doença relacionada com o amianto.
