Odor industrial complex Metropolitan city monitoring Health impact

PDF

This study reviewed the previous odor monitoring statuses of industrial complexes in the domestic metropolitan cities (Ulsan and Daegu) of Gyeongsang Province and their relevant counter-measures. In addition, it identified future technical and management issues and made suggestions on how to overcome them. The statuses and counter-measures were mainly obtained through domestic research studies from the 2020s. The target industrial complexes included manufacturing plants inside metropolitan city areas where severe civil complaints could occur. The counter-measures were generally classified into further in-depth odor analysis through the placement of monitoring equipment at multiple locations, scientific odor prediction and source tracking by integrating regional database systems or applying mathematical models, reasonable diagnosis and follow-up action after the identification of odor issues, and effective mutual communication with on-going or potential civil complaints from nearby residents through the Internet or smartphone apps. Additionally, this study suggested the automation of odor monitoring by using improved technologies with enhanced reliability through machine learning. These technologies would make it possible to organize a feasible monitoring network by deploying multiple low-cost odor sensors with automatic calibration and validation capabilities. Furthermore, this odor monitoring data could be made more effective when implemented together with health impact analyses based on secondary data from employees at workplaces or nearby residents.
