Techniques for Estimating Generation and Non-ventilation Removal Rates of Volatile Organic Compound using the Near-field/far-field (NF/FF) model

Ernest N. Morial New Orleans Convention Center 

In many real-world scenarios, direct measurement data are often limited by high costs. To address these challenges, mathematical exposure models serve as critical supplementary tools. the near-field/far-field (NF/FF) model was developed to partition indoor spaces into two zones: a near-field (NF) representing the immediate vicinity of the source and the worker's breathing zone, and a far-field (FF) representing the rest of the room. NF/FF models are widely used to estimate indoor exposure concentrations; however, their application has largely been restricted to known generation rates and neglected non-ventilation removal, limiting relevance to realistic workplaces.
