Abstract
Synthetic musk fragrances have been measured in water air sediments sewage sludge and biota worldwide As the study of the environmental fate and impacts of these compounds progresses the need for Standard Reference Materials SRMs for these compounds to facilitate analytical method improvement and interlaboratory comparisons becomes increasingly important The National Institute of Standards and Technology NIST issues environmental matrix SRMs with certified concentrations for a variety of persistent organic pollutants including polycyclic aromatic hydrocarbons PAHs chlorinated pesticides and polychlorinated biphenyl congeners PCBs Until now synthetic musk fragrance concentrations have not been reported in NIST SRMs The objective of this study was to provide reference values for several commonly detected synthetic musk fragrances in several NIST natural matrix SRMs In this study five polycyclic musk fragrances HHCB 134678hexahydro466788hexamethylcyclopentaγ2benzopyran AHTN 7acetyl113446hexamethyl1234tetrahydronaphthalene ADBI 4acetyl11dimethyl6tertbutylindane AHMI 6acetyl112335hexamethylindane and ATII 5acetyl1126tetramethyl3isopropylindane and two nitro musk fragrances musk xylene 1tertbutyl35dimethyl246trinitrobenzene and musk ketone 4tertbutyl35dinitro26dimethylacetophenone were measured in selected environmental SRMs Gas chromatography–electron impact mass spectrometry GC/EIMS was used for all analyses HHCB was the most frequently detected synthetic musk fragrance and was detected in SRM 2585 Organic Contaminants in House Dust SRM 2781 Domestic Sludge SRM 1974b Organics in Mussel Tissue Mytilus edulis and SRM 1947 Lake Michigan Fish Tissue It was not detected in SRM 1946 Lake Superior Fish Tissue or SRM 1945 Organics in Whale Blubber Concentrations of HHCB in these SRMs ranged from 112 ng/g in SRM 1947 to 92901 ng/g in SRM 2781 All of the polycyclic musk fragrances were detected in SRM 2781 and all of the target compounds were detected in SRM 2585Certain commercial equipment instruments or materials are identified in this paper to specify adequately the experimental procedure Such identification does not imply recommendation or endorsement by the National Institute of Standards and Technology nor does it imply that the materials or equipment identified are necessarily the best for the purpose
