Notes:
↵1 Reported as the difference between the levels measured in the extracts and the extraction blanks. The approximate reporting threshold is 1 μg/g.
↵2 Minimum refers to the lowest quantity extracted from those materials for which this extractable is reported. Clearly, as no extractable was reported in all materials, the absolute minimum for all resins is “not reported”.
↵3 Sulfur was only reported in one of the test resins.
