A review of human exposure to estrogens and an ecologic study of atrazine exposure and breast cancer incidence in Missouri counties


Estrogens are a broad class of compounds which exert many physiological effects. In addition to gonadal and peripheral endogeneous estrogen production, humans can be exposed to exogenous estrogenic compounds (xenoestrogens) from medicinal, dietary and environmental sources. These compounds can exert effects similar to that if 17⁷-estradiol (E2) through estrogen receptor (ER) mediated mechanisms, or via ER-independent pathways. One such compound is the triazine herbicide atrazine. A number of studies have implicated atrazine as an endocrine disrupting chemical (EDC). An ecologic study of breast cancer incidence and atrazine exposure in Missouri counties was conducted for the combined years of 1996-2002. The objective of this study was to determine if breast cancer incidence rates were associated with atrazine exposure in Missouri counties"--Abstract, leaf iv.
