Cigarette butt is known as hazardous waste with numerous toxic and carcinogenic pollutants which impose serious concern for both the environment and human. Heavy metals are recognized as the most common pollutant in the cigarette butts. The concentration of some heavy metals (cadmium, chromium, nickel, lead and zinc) in leachate obtained from the pilot landfill with commingled waste and freshly smoked cigarettes butts were analyzed. The results showed that the addition of 0.76% (in weight) freshly smoked cigarette butts in landfilled waste increased total heavy metal concentration by 4.8%, while addition of 1.3% (in weight) freshly smoked cigarette butts leads to increased 3.72% of total heavy metals concentrations. An increased 10.52% and 3.43% health risk values were found from the leachate of the landfill pilot, where 1% freshly smoked cigarette butt and a littered cigarette were added, respectively. Overall, it can be concluded that cigarette butt landfilling is not recommended for management of this type of waste and is necessary to be replaced with less hazardous ways such as recycling.
烟头被视为危险废物，含有大量有毒和致癌污染物，这对环境和人类都造成了严重影响。重金属被认为是烟头中最常见的污染物。对从混合垃圾和新吸过的烟头的试验性垃圾填埋场获得的渗滤液中一些重金属（镉、铬、镍、铅和锌）的浓度进行了分析。结果表明，在填埋废物中添加0.76%（重量）新吸过的烟头会使总重金属浓度增加4.8%，而添加1.3%（重量）新吸过的烟头会使总重金属浓度增加3.72%。在试验性垃圾填埋场的渗滤液中，分别添加1%新吸过的烟头和一个乱扔的烟头后，发现健康风险值分别增加了10.52%和3.43%。总体而言，可以得出结论，不建议采用烟头填埋的方式来处理此类废物，有必要用危害较小的方式（如回收利用）来替代。
