Assessment of Dechlorane compounds in foodstuffs obtained from retail markets and estimates of dietary intake in Korean population.
A total of 175 samples, composed of 35 different foodstuffs, were obtained from retail markets in Korea and analyzed to investigate the contamination status and dietary intake of Dechlorane compounds. The concentrations of Dechlorane Plus (DP), mirex, Dechlorane (Dec) 602 and 603 ranged from ND to 169.85 pg/g wet weight (ww), 107.30 pg/g ww, 20.81 pg/g ww, 0.41 pg/g ww, respectively, while Dechlorane (Dec) 604 was not detected in any samples. Strong correlations between anti- and syn-DP and between mirex and Dec 602 were observed. The average anti-isomer fractional abundance (fanti) was 0.78±0.11 which was larger than the technical DP value (fanti=0.75). The estimated dietary daily intake of DP, 11.2×10(3) pg/day, was one to three orders of magnitude higher than other Dechloranes. Grain was the most contributed food group to dietary daily intake of DP for Korean population.
