a
When at least half of the sample results were below the limit of detection, the LOD was used in the mean calculation and reported as less than the resultant value.
b
A third or less of the sample results contributing to the mean calculation were less than the limit of detection and were replaced by either the LOD /√2 or the LOD/2..
