Smog blankets Bangkok as experts warn of serious threat to public health

ak_smog_1401Bangkok has been engulfed by smog for the past few days as experts warn of the threat to public health if the unhealthy air quality levels persist.

The authorities must take the air pollution problem in the Thai capital seriously and strictly enforce mitigation measures to protect people’s health, academics said, while warning of serious financial costs to match.

They pointed out that the country would face billions of baht in additional health costs unless the severe air pollution blanketing the capital was promptly curbed.

The pollution continued to remain at harmful levels for the third straight day on Sunday (Jan 13) and the situation was likely to remain critical for at least another month due to weather patterns, said Dr Witsanu Attavanich, associate professor of economics at Kasetsart University.

He feared both state agencies and the public were largely underestimating the dangers of air pollution and proper prevention and mitigation measures were still inadequate.

Bangkokians awoke on Sunday morning to find their city once again smothered by thick smog that reduced visibility to just one kilometre in some areas. It was not regular winter fog, but a deadly cloud of fine dust particles and other air pollutants, according to China-based air-pollution monitoring website http://aqicn.org. The site reported that the PM2.5 air-quality index (AQI) in Bangkok on Sunday reached a peak of 195, an unhealthy level, while some areas such as Bang Khen district were at hazardous levels, with PM2.5 AQI at 394 on Sunday morning. The site forecast that Bangkok would face harmful levels every morning for the rest of the week because there was little wind.

Nevertheless, people wearing face masks remained a rare sight around the capital. Many children and seniors could be seen going about their outdoor activities as usual.

“Air pollution is really a silent killer and many Thais underestimate the danger to their health, so not many people protect themselves by wearing a face mask or installing air purifiers at home,” Dr Witsanu said.

The official air pollution warning system is also too weak and does not reflect the true severity of the situation,” he said. “Thais don’t have lungs of steel, so we need to consider the environment and people’s health before we pursue economic growth.”

According to his research on pollution-related health costs in 2017, every microgram of PM10 beyond the safe limit cost the people of Bangkok up to 18.42 billion baht (S$780 million) in medical expenses.

While his research did not examine the financial impact that PM2.5 pollution triggered, Dr Witsanu said medical costs are definitely much higher because PM2.5 has a greater impact on health. The current pollution in the capital will cause immeasurable additional health expenditure, he warned.

“We all know that air pollution is not a new problem in Bangkok and agencies such as the Bangkok Metropolitan Administration (BMA) and Pollution Control Department (PCD) already have mitigation measures to tackle the problem. But our question is whether these measures are being strictly implemented and whether they can truly mitigate the problem,” he said.

He emphasised the importance of the authorities taking air pollution seriously and immediately tackling the problem at its root. He called for monitoring construction sites and limiting cars on the streets, rather than simply telling people to wear face masks. He urged everyone to spread the word about air pollution.

Environmental-health expert Sonthi Kotchawat cautioned that PM2.5 was so harmful because it consists of very fine dust particles small enough to pass through the lungs and enter the bloodstream. Long exposure can cause respiratory diseases, including lung cancer, heart disease and stroke, he said. He added that it was important to mitigate air pollution at its roots by controlling outdoor burning, implementing pollution controls in the transportation sector and curbing the use of fossil fuels.

He urged the PCD to not merely issue warnings, saying its officials are obligated by law to mitigate the pollution at its source and protect the environment and public health.

BMA Environment Department director Chatree Wattanakhajorn said his agency has issued a ban on outdoor burning, was monitoring pollution-control measures at all construction sites and was constantly cleaning the roads.

    Come on now…this is not smog at all.. It is geoengineering fallout. The same junk that we get in California . You can wipe off your windshield and look at the junk under a microscope. It is very tiny fibers and sparkling aluminum particles and other substances. That is why we are seeing a new disease in lungs and digestive tracts based on excess eosinophils for the last 20 years (since geoengineering started). Now diseases associated with asbestos that were once dying out as the exposed population died, are now in a resurgence. Scientists are trying so hard to push this climate change agenda that they will kill us with their weather control agendas. And there still isn’t a facemask that an extreme outdoor athlete can wear for protection against this continuous assault that allows fast and extreme inhalation/exchange of oxygen/air.
