Sample 1Sample 2Sample 3
Not detected means at or below the following lower method calibration limits (MCLs): The 2,3,7,8-TCDD-based MCL
Sample 1Sample 2Sample 3
Not detected means at or below the following lower method calibration limits (MCLs): The 2,3,7,8-TCDD-based MCL—0.01 parts per trillion (ppt), sample weight of 1000 g, IS spiking level of 1 ppt, final extraction volume of 10-50 μL. For other congeners— multiply the values by 1 for TCDF/PeCDD/PeCDF, by 2.5 for HxCDD/HxCDF/HpCDD/HpCDF, and by 5 for OCDD/OCDF.
