Great scientific review about endocrine disruptors. Routes of exposure include ingestion, inhalation, and dermal contact. Also, there may be widely divergent effects of these compounds due to dose. For instance, lower exposure levels may exert more potent physiological effects in some cellular/tissue/systemic contexts than higher exposure levels, and vice versa. Furthermore, there is little research with regard to the effects of simultaneous exposure to multiple endocrine disruptors.
