An elderly patient hooked up to a tangle of tubes lies struggling for breath in a Bangkok hospital as Thailand battles a “drastic increase” in respiratory problems caused by a spike in air pollution.
His wife holds his hand and strokes his face, with a nurse in blue scrubs listening to his chest through a stethoscope.
Every single breath is an exertion.
About 2.4 million people in Thailand have needed treatment for medical problems linked to air pollution since the start of the year, including nearly 200,000 this week alone, according to health officials.
Bangkok and the northern city of Chiang Mai were among the top 10 most polluted cities in the world on Friday, according to air quality monitoring firm IQAir.
Piamlarp Sangsayunh, a respiratory disease specialist at the Central Chest Institute of Thailand in Nonthaburi, says she has seen a “drastic increase in patients since February”.
“The patients usually have respiratory problems like coughing and sore throats,” she said on Friday, adding that eye irritation is also common.
Elderly people are among the most vulnerable to air pollution, which can exacerbate existing conditions, sometimes requiring them to be put on oxygen machines, she said.
But she said those working outdoors – such as Bangkok’s vast army of street vendors and motorbike taxi drivers – were the ones “on the front line” of the crisis.
Uraiwan Chantana, who sells fish balls on the street in Bangkok’s central shopping district, said breathing in toxic air every day made her exhausted, but she could not shut her stall because she had no other way to earn money.
“I feel a burning pain inside my nose and I regularly cough,” she said.
“I feel out of breath when I climb the stairs when I normally didn’t.”
World Health Organisation (WHO) representative to Thailand, Jos Vandelaer, said air pollution was not solely a health issue but also dented economic productivity.
“If people are sick they can’t go to work, there will be a reduction in economic activity,” he said.
The economic cost of air pollution in Thailand in 2019 was equal to US$63.1bil (RM280bil) or 11% of gross domestic product, according to Kasetsart University environmental economist Witsanu Attavanich.
One of the biggest concerns are tiny particles known as PM2.5, smaller than the diameter of a hair, which can penetrate deep into the lungs and even reach the bloodstream.
According to IQAir, in 2022 the average PM2.5 concentration in Thailand was 3.6 times the WHO’s annual air quality guideline limits.
Air pollution was a factor in about 31,000 deaths in 2019 in Thailand, according to WHO data.
Smoke from forest fires, farmers burning crop stubble, as well as vehicle emissions and heavy industry-generated fumes, are among the main causes of toxic smog in the kingdom. — AFP
