The U.S. Environmental Protection Agency (EPA) reassessment of the toxicity of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDF) and dioxin-like polychlorinated biphenyls (PCB) identifies ingestion as a key route of human exposure to these compounds. The reassessment, however, found that everal potentially key routes of ingestion had not yet been thoroughly investigated. Vegetable oils, of concernd due to their high fat content, were among the food items for which only limited data (and none from North America) could be found. This paper addresses experimental procedures adapted to simultaneously determine PCDD/PCDF and dioxin-like PCBs in edible vegetable oils and provides a brief discussion of results obtained for thirty oil samples taken in 1996
