摘要：

Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), dioxin-like polychlorinated biphenyls (DL-PCBs), polybrominated diphenyl ethers (PBDEs), and hexachlorobenzene (HCB) concentrations were determined in abdominal fat samples from 30 cattle. The relationships between chemicals, age, and gender were investigated. The concentration of PCDD/Fs ranged from 0.01 to 1.36 pg TEQ g(-1) fat, DL-PCBs ranged from 0.17 to 1.64 pg TEQ g(-1) fat, PBDEs ranged from 135 to 725 pg g(-1) fat, and HCB ranged from 25.5 to 2061 pg g(-1) fat. A comparison between cattle's age and gender vs. the concentration of contaminants revealed higher concentrations of PCDD/Fs and DL-PCBs in cattle aged more than 3 years; no difference between genders was apparent. Moreover, the concentrations of PBDEs in cattle fat did not correspond with the age of cattle. Relative to cattle 1.5-2.5 years of age, cattle aged 3 and 4 years had higher concentration of HCB but the concentration difference was not clear at age 5. Human exposures to these compounds from beef sources were calculated based on beef consumption. (c) 2012 Elsevier Ltd. All rights reserved.
