In a bid to counter air pollution in Bangkok, Thailand officials have turned to drones for answers. Early into 2019, the city’s air quality was reported to hit PM2.5, which meant that the air was full of particles with a diameter of 2.5 microns, reaching 185 micrograms per cubic meter.
To put the scale into perspective, PM2.5 dust particles have a diameter nearly as wide as one-third of human hair.
With the air pollution hazards marked at levels above 150 micrograms, the result was enough to cause damage to the lungs of the average civilian. As can be imagined, these particles can cause irreparable cardiovascular damage. In fact, the World Health Organization states that around 7 million people die due to air pollution in a year, with 4.2 million directly attributed to poor outdoor air quality.
