| 英文摘要 | Concentrated animal feeding operations have been recognized as one of the most important contributors of natural estrogens which show significant endocrine-disrupting properties in aquatic environments. In this study, the concentrations of 17a-estradiol (17a-E2), 17c-estradiol (17c-E2), estrone (E1), and estriol (E3) in several matrices, including soils (surface and deep), sediments (surface and deep), and groundwaters, around a typical dairy farm were surveyed using gas chromatography/mass spectrometry. Of the two farmlands, surface and subsurface sediments in waste lagoon and along effluent drainage drench, the concentrations of 17a-E2, 17c-E2, and E1 ranged from below detection limit to the highest level of 6.60 g/kg, except that E3 was not detectable. Three estrogens of 17a-E2, 17c-E2, and E1 with the concentrations of 3.18-31.61 ng/L were observed in two groundwater samples. The results clearly demonstrated the vertical migration and horizontal transport of estrogens in the investigated area. Within 750-m distance, it was observed the attenuation of 17-E2, 17-E2, and E1 along the effluent route and the horizontal migration of estrogens was less than 1,350 m in this survey.
