N2 - A municipal sewage sludge from Syracuse, New York and a largely domestic sludge from Sodus, New York were analyzed for polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) using combined gas chromatography and high resolution mass spectrometry (GC/HRMS). Concentrations in ppt of the following PCDDs were found in the syracuse sludge: tetrachlorodibenzo-p-dioxins (TCDDs), 150, hexachlorodibenzo-p-dioxins (HxCDDs), 2100, heptachlorodibenzo-p-dioxins (HCDDs), 6300, octachlorodibenzo-p-dioxins (OCDDs), greater than 60,000. The following ppt concentrations were found in the Sodus sludge: TCDDs, 7200, HxCDDs, 300, HCDDs, 900, OCDDs 7500. The TCDD was a single but not the highly toxic 2,3,7,8-isomer. PCDFs were mostly nondetectable in the sludges. The toxicology and potential for environmental contamination by these compounds are discussed.
