• 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.
