This Standard specifies a method for the determination of tetra-through octachlorodibenzo- p-dioxins, tetra-through octachlorodibenzofurans and dioxin-like PCBs in flue gas which are generated by combustion and chemical reactions, and discharged to a flue, stack or duct (hereafter referred to as duct) in stationary source emissions using a gas chromatograph/mass spectrometer (hereafter referred to as GC-MS). The GC-MS employed in this Standard shall be the double-focusing mass spectrometer (hereafter referred to as MS) where the capillary column of a gas chromatograph (hereafter referred to as GC) is used and its resolution is 10 000 or more.

WARNING Since dioxins are very toxic, inhalation, accidental ingestion, direct contact to skin, etc. shall be avoided as much as possible, and ventilation of pretreatment room and analysis room and control of waste liquid and waste shall be sufficiently carried out. Since the health of the measurer may be damaged by inhalation or accidental ingestion of other drugs, solvents, etc., the handling shall be carried out as carefully as possible, and attention shall be paid to sufficient ventilation in the laboratory.
