Proposed VOC Sampling Network for a Complex Urban/Industrial Area: Fairfax Sampling Proposal

摘要

The report is part of the National Network for Environmental Management Studies under the auspices of the Office of Cooperative Environmental Management of the U.S. Environmental Protection Agency. The study develops a sampling scheme for the Fairfax Industrial District located in Kansas City, Kansas. The Fairfax Industrial District is a complex urban/industrial area possessing a wide variety of VOC sources. The complexity of the site makes individual source monitoring and discrimination difficult with existing sampling networks. However, the addition of a sequential, multi-collection sampler will improve existing sampling networks such that individual source contributions within a multiple VOC source environment can be identified and quantified. The overall objective of the study will be the development of a sampling protocol and design that is simple to operate and will allow a regulatory agency to monitor a given urban/industrial source with a reasonable degree of confidence. The objective will be developed using a four step procedure consisting of: a site characterization to collect and organize VOC emission and background information, VOC and micrometeorological data collection using the sequential, multi-collector method, analysis and integration of resulting data using gas chromatography/mass spectrometry and back trajectory analysis, and an interpretation of resulting data using a discriminant matching technique.
