Abstract

Recently, the recycling on the increasing organic waste and its application such as the utilizing to resources to the green field and compost manure are great concern. The composting of sewage biosoilds must be continued to increase.On the other hand, it was reported that the higher level of synthetic fragrance materials, which are widely used as personal care products, was detected in the sewage biosoilds.The present study, we have investigated the persistent of synthetic fragrance materials, such as 7-acetyl-1,1,3,4,4,6-hexamethyl- tetrahydro naphthalene (AHTN) and 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8- hexamethyl-cyclopenta-?-2-benzopyrane (HHCB), HHCB related compound (HHCB-lactone) and [1,2,3,4,5,6,7,8-octahydro-2,3,8,8- tetramethylnaphtalen 2yl] ethan -1-one (OTNE) in compost manure.As the results, we have identified ND ~ 5.3mg AHTN/kg, ND ~ 4.2mg HHCB /kg, ND ~ 14.2mg HHCB lactone /kg and ND ~ 2.1mg OTNE/kg in compost samples from sewerage biosolids.In this study, it is revealed that the higher level of synthetic fragrance materials such as AHTN, HHCB, HHCBLactone and OTNE still contained in the compost manure from sewage biosoilds.It means that the synthetic fragrance materials related compounds do not remove though-out the manufacturing process. It is concern that the recycle usage of the compost manure by sewage biosolids may cause an additional pollution of soil by the synthetic fragrance materials related compounds.
