Feminization of Longnose Dace (Rhinichthys cataractae) in the Oldman River, Alberta, (Canada) Provides Evidence of Widespread Endocrine Disruption in an Agricultural Basin
Table 1
Concentrations are ng/12 L of 28 target compounds measured by ultratrace analytical gas chromatography-high-resolution mass-spectrometry in river water from 7 sites on the Oldman River, Alberta, Canada during September, 2009. Many of these compounds are hormonally active or are suspected to be hormonally active. The contaminants are grouped according to their functionality (headings in italics) to facilitate identification of potential sources and are used in subsequent interpretations.
