Subject(s):Hormones -- Environmental fate

Abstract:Dairy products are a staple of the American diet. The main ingredient of the dairy industry, milk, has a byproduct even before it reaches the pasteurizing factory. For cows to produce milk, they need to have given birth recently. Pregnancy and lactation hormones include estrogen compounds. These hormones are excreted through urine and feces. Liquid manure and wastewater from precipitation and washing processes of the herd end up in a series of dairy farm lagoons designed to remove solids from the water. What happens to the estrogen compounds? How can we prevent hormones from contaminating the environment and causing detrimental effects in aquatic species? One research query is to determine if the lagoons have long enough retention times for hormones to degrade. Results appear in Wei Zheng, Xiaolin Li, Scott R. Yates, and Scott A. Bradford (2012).
