An Evaluation of the VOST Method for non-Halogenated Compounds at a Agricultural Chemical Manufacturing Facility

摘要

Laboratory testing and one field evaluation study have been performed to assess the performance of the VOST method non-halogenated volatile organic analytes listed in Title III of the Clean Air Act Amendments of 1990. This paper reports on a second field evaluation study performed at a different source category to demonstrate that the methodology is not source-specific. An incinerator that burned chemical waste was selected as the second test site. The field test was designed according to the guidelines of EPA Method 301, using gaseous dynamic spiking. Volatile organic compounds were spiked into two of four quadruple VOST trains as a gaseous spike. A minimum of ten quadruple sampling runs each was performed for VOST. Each quadruple run used four collocated sampling probes attached to four similar sampling trains, with two spiked trains and two unspiked trains.
