1.1 This test method covers analysis of nonylphenol (NP), nonylphenol monoethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), octylphenol (OP), and bisphenol A (BPA), referred to collectively as target phenols (TPs), in soil, sediments, and biosolids by extraction with acetone, filtration, dilution with water, and analysis by liquid chromatography/tandem mass spectrometry. The sample extracts are prepared in a solution of 75 % acetone and 25 % water because TPs have an affinity for surfaces and particles that is more pronounced at lower concentrations. The range of applicability of the test method is shown in Table 1. The method may be extended outside of these ranges depending on additional performance studies not undertaken here.
