In an investigation in 2007 also in Busan in which the amount of these components taken into human bodies was measured, it was found that 0.028 to 0.038 pg-TEQ/kg/day was taken in the day when kosa fell, more than double 0.01pg-TEQ/kg/day that was taken in an ordinary day.
また同じく釜山で、2007年に人体への摂取量を調べた調査では、通常時は約0.01pg-TEQ/kg/日なのが、黄砂の日は0.028-0.038pg-TEQ/kg/日と、2倍以上になるという結果が出ている。
