室内空气品质研究的趋势和面对的挑战

人类90％的时间在非工业建筑环境中度过，而室内空气品质（IAQ）学就是研究在非工业建筑环境下，空气中影响人体健康的污染物来源、污染程度大小、产生的后果及其控制和管理方法等。本文主要讨论目前的研究发展趋势，介绍最新的研究成果。首先，提出并分析了本领域研究的七大发展趋势，取得的成就及存在的问题；然后，指出了五个研究发展中应注意的问题，藉此对未来短期内的发展方向提出建议；最后，讨论了三个长期发展的目标。提出IAQ领域的战略性发展方向。

Indoor air quality research trends and future challenges

Indoor Air Quality (IAQ) in this lecture denotes the interdisciplinary science that studies the source, magnitude, effect, control and management of public exposures to airborne pollutants in non - industrial environments, These are the environments where individuals typically spent over 90 percent of their day, The goal of this lecture is to motivate discussion on present trends and, to a lesser extent, findings of recent and ongoing IAQ research. Toward this goal, the first objective of this lecture is to present and discuss research trends and point out strengths and limitations of broad areas of inquiry. Seven such trends were identified from the assessment of publications found in an electronic literature search. The second objective of this lecture is to suggest future directions by posing questions that should be addressed in the shortterm of future IAQ research. Five such questions or research enigmas are formulated and discussed. The final objective of this lecture is to identify strategic, long - term, research objectives of IAQ researchers. Three such long - term goals are discussed briefly.
