ABSTRACT
Many steroids, hormones, and their metabolites are being detected in the environment in waters, soils, sediments, and biosolids. The identification and quantification of such pollutants at trace concentrations have therefore assumed significant importance similar to many other classes of emerging pollutants. The US EPA Method 1698 describes an analytical procedure for the determination of steroids and hormones in aqueous, solids, and biosolid samples. The chapter lists the names and the Chemical Abstracts Service (CAS) registry numbers for the steroids and hormones determined by this method. It also lists the internal standards and the labeled isotope used in this method. The laboratory performing analyses of steroids and hormones is required to operate a formal quality assurance program. The program broadly consists of initial demonstration of the laboratory's capability, analysis of samples spiked with labeled compounds to evaluate and document data quality, and analysis of standards and blanks as tests of continued performance.
