ABSTRACT
Hexachlorobutadiene (HCBD) is a persistent organic pollutant (POP), and a toxin whose primary target organ is the kidney. Consequently, quantifying the amount of HCBD in food is essential for determining whether it poses a health risk. The current study established and validated an analytical method for assessing HCBD in food using gas chromatography/mass spectrometry (GC/MS). Subsequently, we conducted for the first time a risk assessment of HCBD through Korean food consumption. The ranges of HCBD concentration in 595 food samples were as follows: not detectable (nd)-0.947 ng/g for agricultural products, nd-0.920 ng/g for animal products, nd-1.323 ng/g for fishery products and nd-1.081 ng/g for processed food products. The daily intakes of HCBD for the general population were 0.22 ng/kg body weight (b.w.)/day for agricultural products, 0.30 ng/kg b.w./day for animal products, 0.07 ng/kg b.w./day for fishery products and 0.33 ng/kg b.w./day for processed food products. These exposure levels are below the tolerable daily intake (TDI, 2 µg/kg body weight/day) established by the National Institute of Food and Drug Safety Evaluation (NiFDS) in the Republic of Korea. Taking into account the risk index of 0.011%, we can, therefore, conclude that there are no health concerns for the Korean population.
