摘要	This project is to exploit a mobile laboratory to investigate air pollution events in the surroundings of industrial parks. A novel methodology integrating monitoring techniques with model simulation was developed and tested with an aim to tackle odorous or toxic air quality problems around industrial parks. The project has entered its final year of a three-year period. In this year (2012), at the final stage of the project, three major tasks were accomplished adding tremendous versatility and ingenuity to the existing mobile laboratory technologies. The first task was to access the overall performance of PTR-MS by tesing 25 target compounds with distinct odors. There are two parts involved: One is to calculate and update the reaction rate coefficients (kc) from the physical properties of these species (i.e., polarizability, dipole moment and moment of inertia) using the computational method of electronic structure. The other is to validate the accuracy of PTR-MS input with calculated kc by preparing gas standard mixtures of the 25 target compounds based on the permeation and GC-FID method. The second task was to design a triggering system with the use of PTR-MS and a sampling apparatus to allow instantaneous sampling at the events of high levels of VOCs. The concept was tested in field at both Hukou and ChungLi industrial parks. Several prominent pollutants (such as methanol, acetaldehyde, acetone, methyl ethyl ketone, etc.) were found and thus used as the triggering gases to active canister sampling at preset levels. The filled canisters were then analyzed by GC/MS in-lab for 108 VOCs to characterize event relavent composition. To have a comprehensive knowledge of the occurrence of pollution events at the monitoring site, wind-model simulation coupled with detailed meteorological data collected in Hokou industrial park during summer resulted in excellent agreement between measurements and simulations. The wind model was successfully used as a diagnostic tool to explain the cause of an event and to visualize the transport routes of plumes to the receptor site.
