在萨吉诺河和海湾以及休伦湖[美国、加拿大]的沉积物中发现了多氯二恶英和呋喃。二恶英和呋喃的同系物分布表明，燃烧可能是这些化合物的主要来源。已测年沉积物岩心的深度与浓度分布表明，自 1940 年以来，二恶英和呋喃的排放量大幅增加。这种历史增长与氯化有机化合物的生产、使用和处置趋势相似，表明焚烧炉燃烧燃料中存在的二恶英和呋喃的氯化前体可能是这些沉积物中发现的二恶英和呋喃的主要来源。
Polychlorinated dioxins and furans were found in sediments from the Saginaw River and Bay and from Lake Huron [USA, Canada]. The congener distributions of the dioxins and furans indicated that combustion may have been the major source of these compounds. The depth vs. concentration profiles in dated sediment cores showed that emission of dioxins and furans had increased greatly since 1940. This historical increase was similar to trends for the production, use and disposal of chlorinated organic compounds and suggested that chlorinated precursors of dioxins and furans, present in incinerator combustion fuels, may have been the main source of the dioxins and furans found in these sediments.
