The Ministry of Environment has formulated "Standards for Stationary Sources Air Pollutants Emission Standards " to control pollutants in the air. Among them, the odor pollutant analysis method uses the "Odor Pollutant Determination Method-Three Points Comparative Sensing Bag Method" announced by the National Environmental Research Institute. ” (NIEA A201), but the conditions for the sampling and analysis process are very strict. This project intends to evaluate the portable technology of electronic sensors for odors in the Middle East to collect odors in areas where odors are often reported (such as animal husbandry, industrial areas, catering industries etc.)) Simultaneously compare the sensory perception discrimination of the odor Hunan electronic sensor and the announcement method to evaluate the odor Hunan electronic sensor's future evaluation of environmental odor detection and smell.
The research process planning of this project includes inviting sensor manufacturers to participate and field sampling analysis. The field sampling analysis is divided into two stages. Finally, the feasibility of the field application of electronic odor sensors will be evaluated based on the implementation results, and a plan will be developed. Possible technology for electronic sensors of odor pollutants.
This year, sensor manufacturers have been invited to participate, and a total of three instruments have been confirmed to be used, including the GROD taste detector of Green River Technology INC., the Cosmos electronic nose odor detector (model: XP-329ⅢR) of Auto Art Engineering Company, WT1 outdoor air monitoring site of SCIENTECH CORPORATION.The on-site sampling locations are selected from 111 years of odor information provided by the Environmental Protection Agency of Taichung City, Changhua County and Yunlin County as a spot check. We completed two batches of 11 points of sampling in each field, a total of 66 points of field sampling analysis and instrument testing, and an additional 33 points of supplementary testing.
After analysis and testing results, there is no correlation trend in the results. It is judged that the existing commercially available electronic odor sensors have not been able to directly replace the three-point comparison sniffing bag method, and it is low probability to directly replace the three-point comparison sniffing bag method.
