Poultry manure contains free and conjugated forms of the natural estrogens 17β-estradiol and estrone, which can be transported to receiving waters via runoff when land-applied. Previous studies have demonstrated estrogens in runoff from poultry manu

Municipal biosolids contain natural estrogens, e.g., 17ß-estradiol (E2) and estrone (E1), and synthetic estrogens, e.g., 17a-ethinylestradiol (EE2), which can be transported to receiving waters via runoff when land-applied as fertilizer. Previous st

Roxarsone has been used extensively in the broiler chicken industry. We reviewed the environmental concerns of this usage. To summarize, arsenic added to poultry feed as roxarsone ends up in poultry litter. Fresh litter contains predominately roxarso
