Hanoi: The World’s Most Polluted City and Its Impact on Health and Travel

Hanoi, the capital of Vietnam, ranks as the most polluted city in the world

Hanoi, the capital of Vietnam, has been identified as the most polluted city in the world. The pollution in Hanoi is mainly caused by thick smog generated from high levels of particulates, which come from factors such as widespread construction, vehicle emissions, carbon emissions from coal plants, and agricultural burning. According to Swiss air quality firm IQ-Air, these sources contribute to Hanoi’s poor air quality.

The negative effects of the pollution in Hanoi are severe, with levels of PM2.5 pollutants classified as “very unhealthy,” exceeding the World Health Organization’s (WHO) annual guideline by over 24 times. Exposure to air pollution or PM2.5 pollutants has been linked to serious health conditions such as strokes, heart disease, and lung cancer. Due to these health risks, healthcare authorities have advised residents to wear masks and limit outdoor activities. A recent report by the World Bank reveals that 40% of Hanoi’s population is exposed to air pollution levels nearly five times higher than the WHO guidelines.

Residents of Hanoi are feeling the impact of the pollution on their health. Duong Kim Oanh, a 58-year-old resident, expressed concerns saying, “This is damaging for our health. I think Hanoi’s pollution is caused by a large number of personal vehicles and the fine dust from all the construction, plus this cold weather.” The pollution in Hanoi has also been affecting air travel, with nearly 100 flights to and from the city’s international airport experiencing delays or being redirected to other cities last month due to dense fog caused by the pollution, leading to reduced visibility.
