...components of smoke that paralyze the cilia, and are therefore important in bronchitis and related diseases, are largely carbolic and other acids. A proportion of these (up to 90% in the case of phenol) can be removed by cellulose acetate filters. Other cilia-damaging components, such as acetaldehyde and acrolein, are cut down by an activated charcoal filter, especially if the charcoal is compressed. A still better way, said Wynder and Hoffmann, is to filter the smoke through water and then through compressed charcoal, but so far this is not practicable -except, conceivably, in homes with filter-tipped hookahs...
...cause of lung cancer is still unknown, but there is clinical evidence linking cancer with foreign matter in the respiratory system. Cilia are thin hairs that prevent such particles from lodging in the tract. The charcoal granules in the compartmentalised Lark filter adsorb such gases as hydrogen, cyanide, formaldehyde, acrolein, and ammonia, which interfere with this process...
...valuable lesson in public health: disease can be transmitted by polluted water. In the years since, along with his progress in sanitation and health, man has picked up new ways of polluting his environment. The new, more subtle contaminants bear such exotic names as alkyl benzene solfonate and acrolein, and they differ in one major respect from the contaminants of a century and a half ago. They are man-made-the undesirable byproducts of technological progress...
