Protecting children from environmental threats like lead poisoning and pesticides is becoming a greater public health priority. Research dedicated to prenatal and pediatric environmental health (PPEH) coupled with the green movement and increasingly intensive parenting has created a new, dynamic environment in which information can play a critical role in determining protective behaviors. New and expecting mothers particularly vulnerable to toxic chemicals in the environment are exposed to health information from a variety of sources, including the mass media. Despite several decades of environmental and health communication research, the nature and effects of environmental health information available to mothers have received limited research attention. This dissertation launches a new exploration into environmental health communication by asking three overarching research questions: (1) how prevalent is PPEH information in the media, (2) is mothers' exposure to such information linked to key outcomes- namely, protective behaviors, behavioral intentions, knowledge, descriptive norms, and perceived threat, and (3) are the effects of such exposure contingent on the relative volume of media coverage PPEH topics receive? To address these questions, four studies were conducted. Study 1, an elicitation survey, determines where mothers routinely come across, or scan, PPE
