One of the most important tasks was to improve respiratory protection, particularly against toxic smokes, which had been a feature of chemical warfare in the latter years of the war. Little was known of the properties and behaviour of particular clouds and of methods which might be used to remove them from the atmosphere. It was recognised that many years of research was required in order to provide adequate understanding and knowledge of the particulates, which could then sanction the design of effective filters for inclusion in the new respirators. Towards the end of the First World War, charcoal was normally used as a filter in...

The future of the respiratory irritants b somewhat difficult to estimate. The experimental work done by the Allies toward the end of, and since, the World War showed conclusively that these compounds an innuendously effective when thermally distilled and disseminated a. toxic smokes while all modem masks contain special filters for protecting against these smokes, the protection is only relative and greatly adds to the breathing resistance of the mask. All things considered, it is believed that these compounds are destined to play an important part in gas warfare of the future. 

The toxicity of tobacco smoke may be decreased by treatment with dilute potassium permanganate solution (Rosenthal 1989). Nascent oxygen from KMnO may oxidize the nicotine and tar components of a smoke stream. Zinc oxide and ferric oxide are found to reduce or eliminate the carcinogens in tobacco smoke (Hardy and Ayre 1987). Amonkar and coworkers (1989) found that hydroxychavicol, a phenolic component of betel leaf, showed protective action against the tobacco-specific carcinogens NNN and NNK. The authors suggest that this compound may reduce the risk of oral cancer...
