Unseasonal, poor air quality has descended on Bangkok and surrounding suburbs threatening people’s health. The problem, which filled the headlines at the end of last year, has returned to parts of the capital over the weekend.

Readings up to 233 have been recorded this morning, well in excess of the 50 micrograms per cubic metre safety level. That means that the general air quality is now ‘very unhealthy’ (chart below).

The Pollution Control Department attributes the worsening air quality to a large high pressure cell, which is covering most parts of the country. The large cell is robbing the centre of Thailand of winds to blow away the local smog. The same weather pattern has brought ‘high season’ weather to the south of Thailand with mostly north-easterly airflows replacing the seasonal south-west monsoon.

The department advises small children, pregnant women, the aged and ailing people to stay indoors or to wear proper face masks if they have to leave their homes.

The prolonged haze problem affected Bangkok and its neighbouring provinces, such as Samut Prakan, Pathum Thani, Nonthaburi and Samut Sakhon, for several months late last year. Many people were forced to wear face masks when they were outdoors and schools were ordered closed for several days by the Ministry of Education as the level of PM2.5 far exceeded the 50-micron level, as set by the World Health Organisation.

At the height of the haze problem, useless water cannons were deployed to try and get rid of the fine dust particles and a fleet of aircraft conducted cloud-seeding operations to ease the pollution problem.

Government claims they’re serious about northern air pollution

Thailand’s northern provinces, particularly Chiang Mai and Chiang Rai, suffer mightily during the annual plantation burning season, infamously known as “smoky season,” when farmers there and in neighbouring Laos, Myanmar and Cambodia burn their fields in preparation for the next harvest. The season lasts from January to April, and during that time Chiang Mai often rates as having the worst air quality in the world. But now the government says it’s taking air pollution seriously and aims to clean up the North.

Chiang Mai’s air quality problems have been a consistent issue, since the northern Thai city was declared ‘most polluted city in the world’ on March 10, according AirVisual.com. The city has ‘won’ the accolade on more than 10 days this year. Adding to the problem, in March and April this year were the forest fires challenging local authorities in the mountains around the city.

Government spokeswoman Narumon Pinyosinwat expressed gratitude to the Chiang Mai Breath Council for its concern on smog in the North and gave assurances the government is earnest about solving the problem. Responding to the council’s demand for successful resolution she said the council makes a huge contribution by monitoring air pollution for the sake of public health.

“The government has tried to solve the problem and assigned local authorities to implement relevant measures. It is never distracted from the effort, despite the coronavirus pandemic.”

“The government is grateful for the Chiang Mai Breath Council’s campaigns for clean air. However, the problem cannot be solved by a single organisation. All parties must join forces. I believe that solutions will improve from now on.”

The government spokeswoman also said that Deputy PM Prawit Wongsuwon would visit Chiang Mai province today to follow up on smog solutions.

“The government understands that it may not be impossible for provincial and regional parties to solve the issue by themselves. We believe that if all parties join hands and watch out for wildfires, which are at the root of the problem and cause of the fine dust, air pollution will be relieved eventually.”

As the annual crop season in north Thailand comes to an end the only good side-effect of the whole Covid-19 outbreak is a drop in the number of fires and plantation burning activity in the past few months.

As a result, Chiang Mai’s Air Quality has experienced significant improvements, according to aqicn.org.

The website data shows that Chiang Mai air quality index reported PM2.5 levels of less than 100 particles per cubic metre for more than two weeks. 50 AQI is the general safety standard in Thailand (and 25 for the World Health Organisation upper limit of safe air quality. On some days in the middle of the highest readings the AQI reached about 500!

The AQI is a standard that indicates the level of air pollution.

• Level 0-50 means good air quality

• 51-100 means moderate quality

• 101-105 will affect sensitive groups

• 151-200 is slightly harmful to health

• 201-300 is highly harmful

• 301-500 means extremely dangerousThe end of the annual crop-burning season - Chiang Mai gets some fresh air | News by The Thaiger
For several days in the past two weeks, Chiang Mai’s air quality index has seen a decrease of more 50%, compared to the AQI levels at the same time in 2019. For two days in a row the northern city scored dubious distinction of having the world’s worst air quality.

2019 – Air Quality Index of 152 | 2020 – Air Quality Index of 57

May 12

2019 – Air Quality Index of 129 | 2020 – Air Quality Index of 69

Smog, smoke and haze have been a widespread public health problem in North & Central Thailand for over a decade. It typically occurs from January to April, but peaks in March as very dry conditions intensify the forest fires. It’s exacerbated by farmers who burn plantation waste to clear land for the next harvest season.

Content creator Manit Monsur, a certified drone pilot, has taken to the skies of Bangkok giving us a unique insight into the sights, sounds and daily life of the Big Mango, before and now. Travel restrictions and business closures have severely impacted on the city’s ability to function. One of the biggest changes, he notes, is the clear skies above one of Asia’s busiest cities.

“Enjoy the empty Bangkok. Despite of the impact on the economy and lifestyle, Covid-19 is really the only thing that is helping reduce the pollution caused by big cities like Bangkok. Now that Bangkok and other big cities in the world sleeps, nature can finally recover from all the damage we human have made over the past hundreds and thousands of years.”

In his second video in the series “Bangkok Lockdown” Manit checks out more of the street life during the current city ‘lockdown’.

“So this week I went out again and shot more footages of the Central Bangkok. I went to Siam Paragon and Chong Nonsi Bridge this time. Watch the vlog for more information and enjoy the empty Bangkok. Despite of the impact on the economy and lifestyle, Covid-19 is really the only thing that is helping reduce the pollution caused by big cities like Bangkok.”
