The recent report of the U.S. Environmental Protection Agency on the respiratory health effects of passive smoking (1) and the known adverse effects of active smoking emphasize the need to quantify the exposure of the U.S. population to tobacco smoke. Measurements of cotinine (a nicotine metabolite) in serum, urine, and saliva have been used effectively to quantify exposure to tobacco smoke (2-10). As part of the Third National Health and Nutrition Examination Survey (NHANES III), CDC's National Center for Environmental Health and National Center for Health Statistics is measuring serum levels of cotinine to assess exposure to tobacco smoke by persons in the United States aged > or = 4 years. This report presents preliminary findings on the first 800 persons in this survey of tobacco-smoke exposure.
美国环境保护局最近关于被动吸烟对呼吸健康影响的报告（1）以及主动吸烟已知的不良影响，都强调了量化美国人群接触烟草烟雾情况的必要性。血清、尿液和唾液中可替宁（一种尼古丁代谢物）的测量已被有效地用于量化接触烟草烟雾的情况（2 - 10）。作为第三次全国健康和营养检查调查（NHANES III）的一部分，疾病控制和预防中心的国家环境卫生中心和国家卫生统计中心正在测量可替宁的血清水平，以评估美国4岁及以上人群接触烟草烟雾的情况。本报告介绍了这项烟草烟雾接触调查中前800人的初步调查结果。
