This study investigates the Impact of Incremental Incense Stick Consumption on PM2.5 Loading, focusing on the relationship between source intensity and indoor air quality degradation. The research objectives are: 1) to quantify and compare the PM2.5 mass loading generated from burning 2, 5, and 9 incense sticks; 2) to analyze the incremental accumulation patterns within a simulated environment over a fixed temporal scale; and 3) to evaluate the implications for public health regarding hazardous exposure. The experiment utilized dual-sensor monitoring in a controlled environment. The results demonstrate a significant non-linear correlation between incense quantity and particulate density: as incense consumption increased, PM2.5concentrations rose exponentially, frequently exceeding international safety thresholds within minutes. The findings reveal that incremental increases in source material lead to rapid pollutant saturation in enclosed spaces, with PM2.5 remaining at hazardous levels long after combustion. These results underscore the severe respiratory risks associated with ritualistic smoke and emphasize the need for source reduction and enhanced ventilation to improve indoor air quality.
