The effectiveness of filter tips for reducing cadmium, tar, nicotine, carbon monoxide and carbon dioxide in cigarettes was studied. The cigarettes were made from tobacco grown on municipal sewage sludge-amended soil and were therefore high in cadmium. When machine-smoked, filter tips did not result in a significant reduction of cadmium deposited on Cambridge filters. This may indicate that a considerable fraction of cadmium is present in the vapor phase of the smoke and therefore not reduced to the same extent as the tar by certain filters. Nicotine and carbon monoxide were reduced to a lesser extent than tar. This indicates that the filter tip has influenced the combustion of the tobacco column during smoking.
研究了滤嘴对减少香烟中镉、焦油、尼古丁、一氧化碳和二氧化碳的效果。这些香烟由种植在城市污水污泥改良土壤上的烟草制成，因此镉含量很高。当用机器抽吸时，滤嘴并没有显著减少沉积在剑桥滤片上的镉。这可能表明相当一部分镉存在于烟雾的气相中，因此不会像焦油那样被某些滤嘴减少到相同程度。尼古丁和一氧化碳的减少程度低于焦油。这表明滤嘴在吸烟过程中影响了烟柱的燃烧。
