Rama II Road, which is a key route for people and cargo heading to the country’s South, has been blanketed with a dangerous level of PM2.5 dust particles for several days already. According to the Pollution Control Department (PCD), the amount of PM2.5 particles should not exceed 50 micrograms per cubic metre of air. The World Health Organisation says PM2.5 dust particles, which are 2.5 microns in diameter or smaller, are carcinogenic. The affected areas include the front of Kasetsart University in Bang Khen district (106 micrograms); Charan Sanitwong Road in Bang Phlat district (94 micrograms); Bang Kho Laem district (92 micrograms); Bueng Kum district (92 micrograms) and Bang Khunthien district (91 micrograms). BMA has also dispatched drones to spray water in the hope of lowering the dust particles.
