吸烟是诱发肺癌的重要因素,但不是唯一的因素。因此,随着吸烟诱发肺癌的肯定,对肺癌的非吸烟病因的研究逐渐引起了重视。目前,在这一领域的研究中,室内小环境污染是一个热点。厨房烟尘是室内空气污染的主要来源之一,它主要来自燃料的不完全燃烧和烹调时的食用油油烟雾。这些物质可能在肺癌的发生上起一定的作用,为此,我们用Ames试验对某些食用油油烟凝聚物的致变性进 Smoking is an important factor in lung cancer induction, but it is not the only factor. Therefore, with the affirmation of lung cancer induced by smoking, the study of the cause of non-smoking of lung cancer has gradually attracted attention. At present, in the research of this field, the pollution of indoor small environment is a hot spot. Smoke in the kitchen is one of the main sources of indoor air pollution. It mainly comes from incomplete combustion of fuel and cooking oil fumes during cooking. These substances may play a role in the development of lung cancer. For this reason, we used the Ames test to determine the mutability of some edible oil fume agglomerates.
