The IQAir report, produced by a Swiss organization monitoring worldwide air quality, focused on fine particulate matter, known as PM2.5, which is among the smallest yet most harmful pollutants. PM2.5 originates from various sources, including fossil fuel combustion, dust storms, and wildfires. Due to its minuscule size—measuring 1/20th the width of a human hair—it can bypass the body’s standard defenses and enter the lungs or bloodstream.

These particles cause inflammation and irritation and are also linked to respiratory diseases. Exposure to this pollutant can cause heart attacks and cancer.

As per the World Health Organization (WHO), the average yearly levels of PM2.5 must not exceed 5 micrograms per cubic meter.

Byrnihat, an industrial city located in northeastern India, reported a PM2.5 level of 128.2 last year, which exceeds the World Health Organization’s standard by over 25 times.
