Sterols and hormones belong to a large group of naturally occurring, synthetic lipids or lipid-soluble chemicals called steroids, which have a diverse repertoire of physiological functions and activity. Steroid compounds, including sterols and hormones, have a variety of health, agricultural, and industrial applications.
Hormones can be released into the environment from water treatment plants, agricultural runoff and other sources. Endocrine-disrupting compounds in the environment are of great concern because even trace, parts per trillion levels have been linked to adverse effects in aquatic organisms.
Sterols such as cholesterol, coprostanol and sitosterol are used as tracer compounds to monitor the sources of organic contamination in ecosystems. Coprostanol, for example, is used as a marker for human fecal matter.
In addition to our pharmaceutical and personal care product (PPCP) methods, SGS AXYS provides multiple options for the analysis of Hormones and Sterols. All methods are applicable in a wide variety of matrices including aqueous, soil/sediment, biosolid, and wastewater treatment plant matrices, and detection limits are usually in the low ng/L range:
Method Description GC-HRMS, similar to EPA 1698 Analysis of 17 hormones and 9 sterols, by MLA-068. LC-MS/MS method, similar to EPA 1694 Analysis of 17 hormones, alongside PPCPs if required, by MLA-075
Metro Vancouver Multi-Year Project to Study POPS and CECs loading in WWTP and diffusion in the Receiving Environment
AXYS has provided Alkylphenol, Sterols and Hormones, Dioxins, PCB congeners, PAHs, Alkylated PAHs, Pyrethroids, and Organochlorine Pesticides analysis for the characterization of WWTP effluent, storm water/ CSO effluent, and its subsequent diffusion to receiving waters and receiving water sediments. Resident fish are also measured on a scheduled basis.
