Pregnancy, lactation, and menopause: how physiology and gender affect the toxicity of chemicals.
We explore ways in which biological events and nonbiological gender factors in women's lives can mediate the toxicity of chemicals to women. We examine the physiologic changes that accompany pregnancy, lactation, and menopause in order to discuss how these changes might influence the target organ dose and distribution of toxic chemicals within women's bodies. We suggest that the interactions between divalent metals and calcium metabolism and those between lipophilic chemicals and fat metabolism could modulate the toxicity of metallic and lipophilic toxins in women over the course of a lifetime. These hypotheses need careful research consideration.
