Nineteen years after Na Phra Lan district in Saraburi -- which is home to a number of major stone mills and cement plants -- was declared a pollution control zone, the government surprised the whole nation by announcing that it is planning to develop a "web-based app" to collect local residents' health information.
The app will be developed by the Ministry of Public Health in response to "growing concerns" over the severe PM10 pollution in the area, which comes from the area's mines, stone mills and gypsum factories.
