| Abstract |
|
A total of 36 volatile organic compounds in water samples collected 3 times (April, August, October) from 33 representative points along the Nakdong river and from 5 industrial complex discharge points were quantitated and summarized as follows. cis-1,2-Dichloroethylene was detected on the 1st, 2nd and 3rd investigations at 4 points (Kumho6, Suyong5, Kumi and Seongseo). 1,2-Dichloroethane was detected at 0.83 μg/L on the 2nd investigation at 1 point (Namgang4-1), and also detected at 0.08 μg/L and 1.55 μg/L on the 1st and 2nd investigations,repectively, at 1 point (Seongseo), and was detected on the 1st, 2nd and 3rd investigations at 1 point (Jinju) at 2.27 μg/L, 9.04 μg/L and 7.22 μg/L respectively. These detected concentration values were less than EPA and WHO drinking water guidelines. Risk assessment performed on cis-1,2-dichloroethylene revealed that the current level of the compound is less than estimated criteria and was not risky. On the other hand, 1,2-dichloroethane exceeded estimated criteria in the risk assessment, while its level was less than the WHO drinking water guideline. |
