Estrogenic Substances. Ii. An Analysis of Plant Sources

Evolutionary Perspectives on Sex Steroids in the Vertebrates

“…Pasture-specific variations in plant-derived estrogens (Walker & Janney 1930) affect livestock fertility according to grazing location. Hormones and hormone analogs are routinely used to manage production of agricultural animals (Brooks et al 1986) and byproducts of steroid analogs used in livestock production have endocrine activity and are likely to affect wildlife Soto et al 2004;Durhan et al 2006).…”

General Fate Model for Microconstituents in an Activated Sludge System

“…These compounds present in the environment as long as they have been made and their ability to mimic endogenous hormones has been known since at least the 1930's (Walker and Janney, 1930) and more importantly by the fish deformation report in UK in 1990s (Desbrow et al, 1998). However, thanks to recent developments in analytical techniques their occurrence can be monitored in various environmental samples at very low concentrations.…”

Endocrine disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs) in the aquatic environment: implications for the drinking water industry and global environmental health

“…It was reported as early as 1930 that certain chemical compounds and plant tissues can have an impact on the hormone system (Walker & Janey 1930;Cook et al 1934). doi: 10.2166/wh.2009.021 With the advances in analytical capability, the presence of a long list of chemically diverse compounds at trace concentrations has been identified in the environment.…”
