Notes:
↵a ME = this element a component of the extracting solution used and thus was not measurable as an extractable.
↵b Detected in only one of the two replicate extracts.
↵c NP = not present in this extract in measurable quantities.
↵d The reported value is the largest amount measured in either the sealed vessel or sonication extract.
