OCCURRENCE OF SYNTHETIC MUSK COMPOUNDS (SMCS) AS EMERGING CONTAMINANTS IN NAKDONG RIVER BASIN, KOREA
The aims of this paper were to investigate and confirm the occurrence and distribution patterns of synthetic musk compounds(SMCs) in Nakdong river basin (i.e., mainstream and its tributaries), Korea. Four (i.e., HHCB, AHTN, AHDI and ADBI) out of six polycyclic musk compounds (PMCs) and one (i.e., Musk xylene) out of 5 nitro musk compounds (NMCs) were detected in 28 sampling sites and HHCB (>50％) was predominant compound followed by MK (16.7％) and AHTN (9.0％). The total concentration levels of SMCs in surface water samples ranged from N.D. to 2147 ng/L. The STPs along the river affect the SMCs levels in river and the SMCs levels decreased with downstream because of dilution effects. The HHCB/AHTN ratios can be used as in indicator of ongoing supply of HHCB and AHTN and the ratioof this study (mean HHCB/AHTN ratio 6.4) was higher than those of other countries (mean HHCB/AHTN ratio 1.7 - 4.3), indicating high usage of HHCB in Korea.
