However, the results indicated that no target compounds were present with the exception of bis(2-Ethylhexyl)phthalate, which could be due to collection or laboratory contamination. The breakdown for Endrin in the Breakdown Standard was 23%. The recoveries for 3 of the 10 compounds in the LCS Standard were below their acceptance ranges.
