A similar situation exists for the case of estrogens, which have also been analyzed by GC or LC coupled to MS or MS-MS. However, LC-MS offers the advantages, as compared to GC-MS, of not requiring prior compound derivatiza-tion and allowing the analysis of both free and conjugated estrogens in a single run. 

The main source of hormones is thus the excretions of the human population and livestock. The make-up and rate of hormone excretion by humans and animals varies as a function of their sex, age, state of reproduction and development, and for animals, their species (Table 3 [67, 79-83]). Human excretions are generally collected in sewers, while animal hormones are concentrated in manure thus, high levels of free and conjugated estrogens have been measured in raw sewage and manure [67, 79, 84-88]. Human hormones will eventually enter the environment mainly via wastewater treatment plants while hormones produced by animals reach the environment via direct excretion in fields or by manure spreading (treated or not) on the land.
