Drinking water samples including home tap water and well water collected in Shiga and Osaka Prefectures, Japan, were analyzed for polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and non-ortho coplanar PCBs (Co-PCBs).
The levels of three chemicals were low ppq (fg/ml) or less than ppq levels in all samples analyzed.
The total daily intakes of them via drinking water were estimated on the bases of their levels and daily intake of water (1.5 L).
Consequently, the amounts of PCDDs+PCDFs and Co-PCBs were revealed to be only 0.00086 to 0.015% and 0.0004 to 0.037%, respectively, of those via food.
