Urban Air Transect Study to Investigate Urban Areas as Sources of PCDDs and PCDFs to the Environment

An urban air transect study was undertaken in Oklahoma City, OK, to investigate whether urban areas represent sources of dioxin-like compounds to the rural environment. This study proposed the hypothesis that the collective human activities characteristic of cities cause urban areas to behave as sources of dioxin-like compounds, and as such, contribute to the general atmospheric background levels of dioxin-like compounds observed in rural areas. To test this hypothesis, a study was designed and field sampling campaigns were conducted in December 2000 and December 2001. This paper reports on the results of that study.
