The major objective of the project aims to develop sampling and analysis technology of organic air pollutants (1-Chloro-2,3-epoxypropane, bis-Chloromethyl Ether, n-Buthyl Acetate, Ethyl Acrylate, Toluene Diisocyanate, Methylene Disphenyl Isocyanate, Diethyl Sulfate, n-Butyl Acrylate ) in ambient and provide test methods established to Environmental Analysis Laboratory, EPA. Follow the previous study, we expected to analysis all organic air pollutants by sampling cans and GC-MS analysis system. However, there are many differences of 8 air pollutants, like the boiling point range of 99 ~ 251 ℃ and saturated steam pressure of 13 ~ 0.00014mmHg and with gas, mist or particulate type exist in ambient. Therefore, in this study, assess epichlorohydrin(ECH), butyl acetate(BA), ethyl acrylate(EA) and butyl acrylate(n-BA) could be analysis by sampling with cans, analyzing by GC-MS method. diethyl sulfate(DES) and bis-Chloromethyl Ether(BCME) that will try to be sampled by sampling tubes and analyzed with GC-MS. Toluene diisocyanate, and methylene disphenyl Isocyanate will be reacted with derivation reagent in impinger and analyzed by HPLC. We developed 8 kinds of air pollutants analyse technology, including methods of quality assurance standards, calibration, detection limits, sample storage time, precision accuracy, etc.,This project demonstrated the detection limits of these developed methods can match the currently EPA regulations for ambient air, and furthermore to provide draft standard operation procedure for EPA.
