The objective of this research was to develop an accurate and precise analytical method to detect and quantitate the 12 ethanesulfonic acid (ESA) and oxanilic acid (OA) acetanilide pesticide degradates in drinking water matrices. This included two steps: evaluating the capability of solid phase extraction (SPE) techniques to concentrate the acetanilide ESA and OA degradates from drinking water; and, evaluating the capability of liquid chromatography/mass spectrometry (LC/MS) techniques to separate and detect ESA and OA acetanilide herbicide degradates in the concentrated sample extracts. Future occurrence data gathered with this developed method can then be used in determining whether to study the health effects of the acetanilide herbicide degradation products, and ultimately whether to regulate these compounds or remove them from the CCL.
