Polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) are classes of related environmental pollutants produced through diverse sources or industrial use and are known to strongly bio-accumulate and produce multiple toxic endpoints in animals and humans 1,2 . The 2,3,7,8- tetrachlorodibenzobenzo-p-dioxin (TCDD) isomer has been classified as a group 1A human carcinogen by IARC 2 . PCBs with dioxin-like properties are often measured with the PCDD/Fs. These three classes of chemicals are listed as persistent organic pollutants (POPs) by the Stockholm convention designated for world-wide reduction in the environment 1 .The primary route of non-occupational human exposure to PCDDs and PCDFs is foods and animal feeds 3-5 . Monitoring programs established are aimed to aid efforts to control contamination in foods and animal feeds 5 . Central to these efforts are confirmatory methods capable of measuring these chemicals at low concentrations in foods. We investigated an orbital trapping mass spectrometer for the measurement of PCDD/Fs and PCBs at low concentrations in whole cow’s milk.
