2 . D i o x i n

m Both the ROK and US analysis detected trace amounts. The

ROK: 0.018 - 4.012 pg-TEQ/g, and the US: 0.001 - 10.087

pg-TEQ/g.

m The US detected 7.44 pg/g and 0.57 pg/g of 2,3,7,8-TCDD at 2

different sampling spots.

- It is more than 100 times lower than the US EPA

recommendation for residential areas (1,000 pg/g,

2,3,7,8-TCDD), so it would not affect human health.
