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.

Annually, over 3 million dry tons of treated sewage sludge (or biosolids) are applied on agricultural lands in the U.S. Nonylphenol is a degradation product of nonylphenol ethoxylate, a surfactant used in industrial detergents and other products, and often found in biosolids.
The title and scope are in draft form and are under development within this ASTM Committee.Back to Top
