Synthetic musks are used as additives in many household *** absorption into the human body,they accumulate and their concentrations in human milk reflect both the mother and her infant＇s exposure *** of four synthetic musks,musk xylene（1-tert-butyl-2,6-dimethyl-2,4,6-trinitrobenzene,MX）,musk ketone（4-tert-butyl-2,6-dimethyl-3,5-dinitroacetophenone,MK）,1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[γ]-2-benzopyran（HHCB） and 7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4tetrahydronaphthalene（AHTN）,were determined in human milk samples collected from Shanghai,Wuxi,and Shaoxing in Eastern *** four synthetic musks were found in most samples analyzed,with HHCB the dominant component followed by *** median（mean） values for HHCB,AHTN,MX and MK concentrations were 63（82）,5（12）,17（24） and 4（9） ng/g lipid weight,*** data suggested the total synthetic musk contamination was low,and the distribution percentage was HHCB 〉 MX 〉 AHTN ≈ *** relative high ratio of nitro to polycylic musk indicated that nitro musks were still widely *** musk concentrations in these cities were not significantly different from each other（p 〉 0.05）.Principal components score plots were obtained,which showed similar exposure *** amount of total synthetic musks in human milk were not associated with mother＇s age,although HHCB was significantly correlated with AHTN（p 〈 0.05）.Daily ingestion of HHCB,AHTN,MX and MK for infants from human milk were estimated as（2526 ± 2926）,（370 ± 524）,（7391 ± 832）,and（277 ± 462） ng/day,*** doses were 1-2 orders of magnitude below the provisional tolerable daily intakes.
