Each sample value is the mean of two samples taken from different experiments (coefficient of variation of the mean of samples taken from different experiments of <5%). Each sample was analyzed in duplicate (coefficient of variation of samples from the same experiment of <0.65%). ND, not detected; NA, not analyzed; TR, trace amounts.
