Background levels and dietary intake of PCDD/Fs in domestic and imported meat in South Korea

Decreasing concentrations of PCDD/Fs in pork based on Korean monitoring in years 2002 and 2005

“…Thus, the cause in the overall decrease in the concentrations is from the greatly decreasing PCDF levels. Figure (Abad et al 2002;Eljarrat et al 2002;Kim et al 2007). …”

“…The US Environmental Protection Agency (USEPA) has estimated that more than 90% of the human exposures to dioxins occur through food consumption, primarily from food of animal origin (USEPA 2004). According to a previous study, toxic equivalent (TEQ) levels of PCDD/Fs in pork were higher than in beef or chicken (Kim et al 2003(Kim et al , 2007. The amount of pork consumption (46.14 g/person day À1 ) has been more than twice the beef consumption (17.39 g/person day À1 ) and almost three times the chicken consumption (15.81 g/person day À1 ) in 2005 in South Korea (Korea Rural Economic Institute 2005).…”

“…The samples collected and analysed in 2002 were from 48 domestic pork and 58 imported pork originated from Austria, Australia, Belgium, Canada, Denmark, France, Hungary, Mexico, Poland, Sweden, and the USA (Kim et al 2007). …”

“…In this study, the monitoring results for the levels of PCDD/Fs in pork in 2005 were compared with the results in 2002 which was previously published (Kim et al 2007), and the dietary intakes of PCDD/Fs from pork were calculated for both years to indicate if a trend could be observed.…”

“…For analysis, an isotope dilution method was used based on USEPA 1613B protocol. The detailed procedure is described in a previous report (Kim et al 2007). Extraction was carried out with hexane after spiking 13 C-labeled PCDD/F standards into the proper amount of melted fat.…”
