To assess the potential benefit of these technologies in reducing the level of release of steroid hormones to adjacent waterways, distribution profiles of nine steroid hormones (pregnenolone, progesterone, dehydroepiandrosterone, androstenedione, testosterone, dihydrotestosterone, estrone, 17α-estradiol, and 17β-estradiol) were determined in raw swine manure, and in solid and liquid fractions separated from ten full-scale manure separation systems. Steroid hormone concentrations, normalized for nitrogen content, were significantly higher in separated solids than in liquids.
