在圣路易斯和华盛顿，华盛顿特区的城市空气微粒中发现了多氯二苯并对二恶英和多氯二苯并呋喃，以及五大湖和皇家岛锡斯基维特湖的沉积物中。在空气微粒和沉积物样本中发现的多氯二苯并对二恶英和多氯二苯并呋喃之间的相似性以及在锡斯基维特湖（一个只能接收大气输入物的地点）沉积物中发现的多氯二苯并对二恶英和多氯二苯并呋喃的存在表明，这些化合物是通过燃烧源排放到大气中的。历史输入的多氯二苯并对二恶英和多氯二苯并呋喃过时的沉积物芯显示了强劲的增长，自1940年以来，这表明，焚烧的氯化有机化合物是一个重要的来源，多氯二苯并对二恶英和多氯二苯并呋喃的环境。
PCDD and PCDF were found in urban air particulates from St. Louis and Washington, D.C., and in sediments from the Great Lakes and Siskiwit Lake, Isle Royale. The similarity between the PCDD and PCDF found in air particulates and sediment samples and the presence of PCDD and PCDF in sediment from Siskiwit Lake (a location which can receive only atmospheric inputs) suggest that these compounds are emitted to the atmosphere from combustion sources. The historical input of PCDD and PCDF to dated sediment cores shows a strong increase since 1940, and this suggests that the incineration of chlorinated organic compounds is an important source of PCDD and PCDF to the environment.
