Bangkok smog prompts Thai PM Prayuth Chan-ocha to warn people to wear masks

Thailand’s prime minister urged residents of Bangkok to wear face masks on Monday after smog covered parts of the capital in what some fear is a harbinger of more pollution to come.

Prime Minister Prayuth Chan-ocha warned in a statement on his Facebook page that the concentration of tiny dust particles called PM2.5 in the air had reached unsafe levels and said he has ordered government agencies to expedite anti-pollution measures. He also asked the construction and manufacturing sectors to reduce activities that release pollutants.

The head of the country’s Pollution Control Department, Pralong Damrongthai, said the visibly dirty air was not caused by smoke originating from forest fires in Indonesia. Since last month, haze blown by monsoon winds from fires in Indonesia has affected nearby countries including the Philippines, Singapore, Malaysia and parts of southern Thailand, raising concerns about aviation safety and health.
