Polychlorinated dibenzo-P-dioxins and dibenzofurans in raw milk samples from farms located near a new resource recovery incinerator

Bovine milk: samples were taken from farms near a new resource recovery incinerator both before and one year after the incinerator went into operation. These samples were analyzed for 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofitrans using liquid-liquid extraction, a semi- automated clean-up procedure and high resolution gas chromatography/high resolution mass spectrometry. No significant differences were observed between the PCDD/F concentrations in the pre-operational and postoperational samples.
