In the Materials and Methods Section, Sample Derivatization for GC-MS Analysis Subsection, the incorrect silanizing reagent is reported. The correct agent is trimethylsilylimidazole, not trimethylsilylacetamide. We tested many derivatizing reagents during method optimization, including trimethylsilylacetamide, but the pentafluorobenzylbromidetrimethylsilylimidazole combination had the highest sensitivity and was used for all measurements.

The Carboxen-PDMS fiber has a thickness of 75 micrometers (µm), rather than 75 millimeters (mm). The Stabilwax fused silica column has a thickness of 1 micrometer (µm), rather than 1 millimeter (mm). Page 1025, Table 2. The unit of the measured and predicted TBA concentration is micromolar (µM), rather than millimolar (mM). This difference is rather significant and can be misleading.
