What is the PM2.5 level in Pakistan and Bangladesh compared to WHO standards?

Question

Accepted Answer

Pakistan and Bangladesh Experience PM2.5 Levels Significantly Exceeding WHO Recommendations

In 2023, both Pakistan and Bangladesh faced severe air quality challenges, with average PM2.5 concentrations substantially higher than the World Health Organisation's (WHO) recommended limits. These levels place them among the world's most polluted countries, indicating a critical public health concern.
Pakistan's PM2.5 Levels

Pakistan recorded an average PM2.5 concentration of 73.7 micrograms per cubic metre in 2023. This figure positions Pakistan as one of the three most polluted countries globally for that year.
Bangladesh's PM2.5 Levels

Bangladesh experienced even higher average PM2.5 concentrations, reaching 79.9 micrograms per cubic metre in 2023. This elevated level also contributed to its ranking among the world's smoggiest nations.
WHO Recommended Standards

The World Health Organisation (WHO) guideline for PM2.5 concentration is a maximum of 5 micrograms per cubic metre. The levels observed in both Pakistan and Bangladesh in 2023 were approximately 15 times higher than this established health standard.
Contributing Factors to High Pollution

Experts attribute the extreme PM2.5 concentrations in South Asia to a combination of climatic conditions, geography that traps pollution, and local factors. These additional contributors include agricultural practices, industrial emissions, and high population density, which collectively exacerbate the air quality crisis.
