Cute bird: Male Tree swallow at Serpentine Fens, Surrey, B.C.
Why this project?
Concern about potential health impacts of environmental contaminants has exploded over the past decade. Much research has focused on endocrine-disrupting compounds š chemicals that interfere with normal hormonal communication (e.g., by mimicking endogenous hormones). In 1991, Soto et al.* discovered that 4-Nonylphenol, a substance leaching from polystyrene centrifuge tubes, caused proliferation of breast cancer and endometrial cells, thus defining 4-Nonylphenol as an estrogenic compound. 4-Nonylphenol and its ethoxylates are widely used by industry as surfactant products and are found in municipal and industrial effluent.
Most studies of Nonylphenol ethoxylates have examined effects of acute, laboratory exposure in rats or aquatic species. Very little work has considered effects in terrestrial species of chronic exposure to low levels of Nonylphenol.
