Air Quality Monitoring for the Purple Line Railway Construction Project (Tao Poon – Rat Burana)

The company conducted air quality monitoring at the Purple Line railway construction site (Tao Poon – Rat Burana) by measuring total suspended particles (TSP) and PM10 levels based on 24-hour averages. Monitoring took place from January to December 2024. The results indicated that air quality remained within standard safety levels, and no complaints were filed. Beyond this project, the same air quality monitoring standards were applied to other construction sites. CH. Karnchang remains committed to upholding air quality control measures to minimize dust dispersion from construction activities.
