US Environmental Protection Agency, National Health and Environmental Effects Laboratory, Duluth, Minnesota 55804, USA
Environ Toxicol Chem 21:1973-6. 2002..We conclude that, although androstenedione was present at easily detectable concentrations in the river water (> 100 ng/L), this compound is not associated with androgenic activity of water from the site... - Cloning and differential expression of estrogen receptor and aromatase genes in the self-fertilizing hermaphrodite and male mangrove rivulus, Kryptolebias marmoratusEdward F Orlando
Department of Biological Sciences, Florida Atlantic University, North, Ft Pierce, Florida 34946, USA

Department of Anatomy and Cellular Biology, Tufts University School of Medicine, 136 Harrison Avenue, Boston, MA 02111, USA
Environ Health Perspect 112:346-52. 2004..Tap water was devoid of hormonal activity. We conclude that feedlot effluents contain sufficient levels of hormonally active agents to warrant further investigation of possible effects on aquatic ecosystem health...
