In these three public service videos from the National Institute of Environmental Health Sciences, learn how to minimize exposure to pesticides, chemical contaminants, and secondhand smoke. Through simple demonstrations, the videos describe the importance of washing the skin after coming into contact with pesticides, how to safely use household chemicals to prevent harmful vapors from escaping into the air, and how to gently confront smokers to avoid secondhand smoke. Two of these videos are available in both English and Spanish audio, along with corresponding closed captions. Includes a background essay and discussion questions.
