All living creatures maintain a regulated hormonal balance internally specific to that organism depending on the demands of the endocrine system. Depending on the hormone, any extracellular supplementation can cause variation in homeostatic functioning of that organism. Estrogenic hormones are known to be endocrine system disruptors with 17�-estradiol being a known carcinogen. This study was concerned with detecting estrogens in chicken waste products such as fresh chicken manure, compost chicken manure, internal chicken house dust and external chicken house dust. Chickens; like all living animals, excrete estrogen in their waste, and they mainly excrete 17a-estradiol, 17�-estradiol, estrone and estriol. Gas chromatography mass spectroscopy were used to analyze the samples as low as parts per million for detection of appreciable amounts of the four main estrogen hormones.
