香烟对人体有害已是不争的事实,并且对人体的危害绝不仅仅是1～2种化学物质[1],只在包装上标明含量焦油、烟碱不足以界定其对机体的毒性,有必要对香烟按其对生物毒性的大小进行分类,让消费者远离高毒性的香烟。常用的研究香烟毒性的生物实验方法有体内和体外两种,但体内试验存在混杂因素多、周期
It is an indisputable fact that cigarettes are harmful to the human body, and the danger to the human body is not limited to only one or two kinds of chemical substances [1]. Only the content of tar is indicated on the package, and nicotine is insufficient to define its toxicity to the body. Cigarettes are classified according to their biological toxicity, keeping consumers away from highly toxic cigarettes.
