Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) were found in annually laminated sediments from Lakes Zurich, Baldegg, and Lugano in Switzerland. Octachlorodibenzo-p-dioxin (OCDD) predominated, averaging approximately 1.3 ppb. The congener distribution indicated that combustion was the source of PCDD and PCDF in these sediments. In these data sediment cores, the authors found that PCDD and PCDF were absent from the sediments before about 1945, but increased thereafter.
