Abstract
Levels of perchlorate in 15 river, 24 soil, 10 dairy products samples were quantified using LC/MS/MS. Levels of perchlorate in 15 river samples ranged from N.D.~77.6 μg/L(mean : 6.55 ± 19.9 μg/L). The concentration level of perchlorate in most river samples were below the Waegwan bridge guideline (6 μg/L in adry season) except two samples. They are sampled collected from Daecheon stream (77.6 μ g/L) and, Jukseong stream (13.0 μg/L). The concentration of perchlorate in 24 soil samples ranged from N.D.~18.24 μg/kg. The highest concentration level among soil samples was 18.24 μg/kg. The sample was collected from high traffic downtown area(D-2). In case of milk and yoghurt, the average concentration level of perchlorate were 8.22 ± 1.88 μg/L and 6.33 ± 1.25 μg/L, respectively. These results indicate that the continuous monitoring of perchlorate in river, soil, and dairy products samples are needed along with investigating perchlorate sources.
