Fig. 1. Dissipation and mineralization of [4–14C]-testosterone and [4–14C]-17ß-estradiol in unamended loam soil and loam soil amended with 10% (v/w) liquid swine slurry or municipal biosolid, incubated at 30°C. Each point and error bars represent the mean value of three replicate samples and corresponding standard deviation. Hormone equivalents correspond to androgenic and estrogenic activities determined by means of yeast androgen or estrogen receptor gene transcription assays.
