Physiochemical Characterization of Steroid Hormones in Soil
Laboratory studies on the fate and transport of reproductive, steroidal hormones and their primary metabolites indicate that aqueous concentrations are short-lived, where dissipation half-lives are on the order of a few hours or days. Dissipation of hormones is caused by i) binding or sorption to the soil and ii) degradation. Sorption of both androgenic and estrogenic hormones occurs predominantly in the organic fraction of the soil and is very rapid through time. Hormone degradation is controlled predominantly by the biological activity of the soil. Hormones will persist in soil where the biological activity is low, such as sterilized or cool low-oxygen soils. Laboratory soil column studies have also indicated that mobility of androgenic and estrogenic hormones is limited, where little will escape the top 5 cm of soil.
