Abstract
The several synthetic fragrance materials are widely used as personal care products. Because of its lipophilic property, they have a possibility to accumulate in living animals. There are a few reports about the information regarding their potential impacts on humans and the environment (especially the aquatic environment).In this study, we have investigated about the removing and discharge of the synthetic polycyclic musk compounds,such as 6-acetyl-1,1,2,4,4,7-hexamethyltetraline (AHTN) and 1,3,4,6,7,8-hexahydoro-4,6,6,7,8-hexamethylcyclopenta-?-2-benzopyran (HHCB), HHCB related compound (HHCB-lactone), [1,2,3,4,5,6,7,8-octahydro-2,3,8,8,-tetramethylnaphtalen2yl] ethan-1-one (OTNE) in sewage treatment plant (STP).As the results, we have identified AHTN 2.3 µg/L, HHCB 4.8 µg/L and HHCB-lactone 1.2 µg/L and OTNE 5.4 µg/L in influent water into the STP. On the other hand, the concentration of AHTN 0.7 µg/L, HHCB 0.9 µg/L and HHCB-lactone 0.9 µg/L and OTNE 0.7 µg/L were detected in effluent water from STP.Their concentrations in sewage biosolids were detected in AHTN 2.1~9.3 mg/kg, HHCB 3.9~11.7 mg/kg, HHCB-lactone 1.8~3.4 mg/kg and OTNE 2.0~9.3 mg/kg.Although the concentration of AHTN, HHCB and OTNE in sewage biosolid was decreased during their treatment process, the level of HHCB-lactone was almost same. This means that HHCB-lactone is derived from HHCB during treatment process in STP.In this study, it is revealed that the 60% of influent volume of PCMs is discharged into effluent water and adsorption by sewage biosolids, and their removal ratio by biodegradation is 40%.
