Due to air pollution a disease called asbestosis can occur.
This disease consists of a respiratory problem caused by inhaling asbestos fibers. This inhalation causes pulmonary fibrosis caused by staying for a long time in an environment that contains asbestos in the air.
Air pollution from asbestos can not only cause asbestosis but also cancer.
Given this information we can say that the correct answer is asbestosis.
