Bioaccumulation and decontamination mechanisms of persistent organic pollutants (PCB, DDT) in bodies of Bactrian camels
chromatography and mass spectrometry method. Concentrations of PCBs and DDT in milk and hump reached a plateau at the end of the 2 months exposure period. Transfer rates into milk ranged between 2% for PCB 101 and 71 % for PCB 180 of the daily dose, which was generally lower than rates observed in ruminants. In the same time, the most
important part of the contaminants has been stored in the humps. At the end of experimentation, the total quantity of PCBs excreted in milk was estimated to 28.6 μg and the total quantity accumulated during the contamination period in humps was 5530 μg. Despite a huge variability between the different congeners of iPCBs, the intermediate storage of
lipophilic compounds in the humps reduced the concentrations excreted in milk but on the other hand would extent the duration of the decontamination period in comparison with ruminants.
