Greenpeace Thailand has called on the Pollution Control Department to devise a law to fight particulate matter with a diameter of 2.5 micrograms per cubic meter or less (PM2.5).
A seminar on Thai air quality hosted by Greenpeace on Friday highlighted that 10 Thai cities were battered by PM2.5 in 2018 including the capital district of Tak province, Phra Pradaeng in Samut Prakan, Muang district of Chiang Mai, and several areas of Bangkok.
The city hit the hardest by PM2.5 last year was Tambon Mahachai in the capital district of Samut Prakan province, with the highest PM2.5 reading of 144 micrograms per cubic meter, exceeding the threshold of 50 micrograms per cubic meter, a level considered safe by the Pollution Control Department.
At the seminar, Greenpeace Thailand urged the government to draft a law to combat fine dust particles, revise the safety threshold down to 35 micrograms per cubic meter, and step up its effort to protect the vulnerable – children, people with congenital diseases, and the elderly.
