^aThe recovered parent SCCPs in different compartments expressed as the mass percentage of initial exposure chemicals. The initial mass was 4000 ng for 1,2,5,6,9,10-HexCD, 8098 ng for 1,1,1,3,8,10,10,10-OctaCD, 7973 ng for 1,1,1,3,10,11-HexCU, and 7980 ng for 1,1,1,3,12,13-HexCT.

^bMean value ± standard deviation, n = 5 for exposure groups, n = 3 for unplanted chemical controls.

^cNo sample for detection.

^dNondetectable, nd.

^eThe summation of different compartment.
