The global atmospheric monitoring plans of the World Meteorological Organization are detailed. Single and multipurpose basic monitoring systems and the monitoring of chemical properties are discussed. The relationship of the World Meteorological Organization with the United Nations environment program is discussed. A map of the World…

Describes guidelines for consideration in selecting sites for air monitoring systems. Careful selection for spatial scale and specific sources assures that the collected data are accurately representing the situation. (Author/MA)

Dispersion, chemical oxidation, and masking are reviewed as techniques primarily employed for odor control. Devices and systems, costs, and problems of measurement are considered in light of environmental agencies' efforts to curb smelly emissions. (BL)

A direct aqueous injection (DAI) technique was compared with the purge method for chloroform measurement in drinking water. The DAI method gave consistently higher values for chloroform than the purge method. The results indicated the need for caution in the interpretation of chloroform and other trihalomethane values generated by DAI. (Author/MA)

By measuring certain transport and degradation properties of chemicals one can establish priorities for the routes and likely points of residence of these materials in the environment. Outlined are transport and degradation tests. (Author/MA)

Trace organic analysis (TOA) is seen as a more useful way to quantify environmental pollutants. Current practices and future trends are discussed in detail. Seven steps in TOA are identified: collection, storage, extraction, concentration, isolation, identification, and quantification. (MA)
