Occurrence and Distribution of Polycyclic Musks in Surface Water from the Songhua River

摘要

Concentrations and distributions of four polycyclic musks (galaxolide (HHCB), tonalide (AHTN), celestolide (ADBI) and phantolide (AHMI)) in surface water from the Songhua River were investigated. Experimental data showed that the Songhua River had been polluted to different degrees except the river's source. Concentrations of HHCB, AHTN, ADBI and AHMI were in the ranges of 6.77-30.65, 2.19-7.97, < LOD-1.94 and < LOD-2.53 ng/L, respectively. The results indicated a low proportion of wastewater burden in this river, and the HHCB and AHTN were the major components. Risk assessments on HHCB and AHTN suggest that the current polycyclic musk levels in Songhua River represent a low potential risk to the aquatic organisms.
