大气污染物的植物监测方法研究

Research on the method of monitoring air pollutants by plants

和传统的监测方法相比,利用植物监测大气污染物是一种经济、简便而且可靠的方法.植物受到不同的大气污染物的危害会表现出不同的受害症状,根据这些受害症状可以判断出大气污染物的种类,并根据植物受害程度和污染时间来估测其质量浓度范围.在总结国内外科研工作者研究的基础上,论述了植物对大气污染物的监测作用的基本原理、监测机理、优点和不足,并列举出大量的监测植物及其监测大气污染物而显示受害症状时的最低质量浓度和时间,最后介绍了大气污染物的植物监测方法和优点.

Monitoring air pollutants via plants is an economic, convenient and credible method compared with the traditional ways. Plants show different damage symptoms to different air pollutants, which can be used to determine the species of air pollutants. Besides, pollutants mass concentration scope can be estimated by the damage extent of plants and the span of polluted time. Based on the research at home and overseas, this paper discusses the principles, mechanism, advantages and disadvantages of plant-monitoring, exemplifies plenty of such plants and the minimum mass concentration and pollution time of the plants showing damage symptoms. Finally, the methods and many advantages of using plants to monitor air pollutants are introduced.
