苔藓与城市空气重金属污染:监测评价方法与新近应用

苔藓监测空气重金属污染作为一个古老命题,近十年来却有崭新进展。引入了大气净度指数(IAP)、空气质量值(LGW)、相对累积因子(RAF)、污染因子(CF)、富集因子(EF)和沉降速率(D)六个监测评价指标,介绍了其评价方法。重点综述了欧洲近十年来重金属沉降苔藓调查的成就与进展,论及了中国的苔藓监测重金属研究现状及发展对策。

Mosses and metropolis airborne heavy metal contamination: methods for monitoring and assessment and recent utilization

As an old topic,moss technique in airborne heavy metal contamination monitoring has been highlighted during the last decade.Various indices for contamination monitoring and assessment,namely index of atmospheric purity,air quality value,relative accumulation factor,contamination factor,enrichment factor,and deposition rate,as well as their analyzing procedures,were introduced in the current study.A worldwide review on this moss technique was provided by the author,with much attention to the European survey of atmospheric heavy metal deposition and the Chinese practice in moss technique.
