Cigarette butts (CBs) can travel via stormwater runoff so they are very common on the beach. While there is evidence they can leach toxic chemicals into water, there is not much information about their behavior in sediment. We buried CBs in aquaria containing marine sediment at a concentration of 0.025 CB/g, and sampled it after 0, 5, 10, 20, 45, and 60 days. The sediment was solvent-extracted and analyzed by GC/MS. The chromatograms were compared to those of CB extracts to look for compounds in common. Nicotine, β-nicotyrine, myosmine, cotinine, linear alkanes, and xylenol were detected in the sediment up to 60 days from exposure so the leachates could have long-term impact on benthic fauna. The tobacco alkaloids or its metabolites could be used as specific markers of cigarette litter in sediment monitoring. These outcomes support the need for stricter regulation on cigarette waste to prevent it from reaching aquatic environments.

烟头（CB）可以通过雨水径流传播，因此在海滩上很常见。尽管有证据表明它们可以将有毒化学物质浸入水中，但有关其在沉积物中的行为的信息却很少。我们将CB埋入浓度为0.025 CB / g的水族箱中，并在0、5、10、20、45和60天后对其进行采样。沉淀物经溶剂萃取并通过GC / MS分析。将色谱图与CB提取物的色谱图进行比较，以查找共同的化合物。暴露后长达60天，在沉积物中检测到了尼古丁，β-烟碱，肌氨酸，可替宁，直链烷烃和二甲苯酚，因此沥滤液可能会对底栖动物群产生长期影响。烟草生物碱或其代谢产物可作为烟尘中沉积物监测的特定标志物。
