Recent public recognition that children are different from adults in their exposures and susceptibilities to environmental contaminants has its roots in work that began >46 years ago, when the American Academy of Pediatrics (APA) established a standing committee to focus on children's radiation exposures. We summarize the history of that important committee, now the AAP Committee on Environmental Health, including its statements and the 1999 publication of the AAP Handbook of Pediatric Environmental Health, and describe the recent emergence of federal and state legislative and executive actions to evaluate explicitly environmental health risks to children. As a result in large part of these efforts, numerous knowledge gaps about children's health and the environment are currently being addressed. Government efforts began in the 1970s to reduce childhood lead poisoning and to monitor birth defects and cancer. In the 1990s, federal efforts accelerated with the Food Quality Protection Act, an executive order on children's environmental health, the Agency for Toxic Substances and Disease Registry/Environmental Protection Agency Pediatric Environmental Health Specialty Units, and National Institute of Environmental Health Sciences/Environmental Protection Agency Centers of Excellence in Research in Children's Environmental Health. In this decade, the Children's Environmental Health Act authorized the National Children's Study, which has the potential to address a number of critical questions about children's exposure and health. The federal government has expanded efforts in control and prevention of childhood asthma and in tracking of asthma, birth defects, and other diseases that are linked to the environment. Efforts continue on familiar problems such as the eradication of lead poisoning, but new issues, such as prevention of childhood exposure to carcinogens and neurotoxins other than lead, and emerging issues, such as. endocrine disruptors and pediatric drug evaluations, are in the forefront. More recently, these issues have been taken up by states and in the international arena.

Childhood lead poisoning is a preventable illness. In the past 3 decades, removal of key lead sources and prevention of exposure in the United States have led to dramatic decreases in population blood lead concentrations and also in instances of severe lead poisoning requiring treatment. From an international perspective, childhood lead poisoning seems to be of greatest concern in developing countries. The phasing out of lead from gasoline is a critical first step in decreasing worldwide blood lead concentrations. However, many focal sources that can cause lead poisoning remain, such as lead from flour mills, lead-glazed ceramics, mining and smelting, and battery repair and recycling. A large and diverse country, such as India, may have many sources of lead. The challenge will be for developing countries to implement effective national and regional efforts to address their specific sources of lead., ABBREVIATIONS.
