This review is extracted from the literature from January 1995 to December 1996 and is an extension of literature previously discussed (A1). The major source of information was Chemical Abstracts Selects: Pollution Monitoring and Air Pollution (Books and Reviews).The organization consists of two major divisions: gaseous methods, which have single-letter designations before reference numbers, and aerosol and particulate methods, which have twoletter designations before reference numbers. Areas that are included are listed in the table of contents.The classification and subclassification scheme is not necessarily technique or pollutant specific. An example occurs in the ozone section (B). This section contains articles that are primarily about ozone techniques. However other articles refer to ozone in sampling and spectroscopy sections. Please read other sections which might contain information of interest.
