In brief
Delhi's decision to shift primary education online highlights the severe health risks posed by hazardous air pollution affecting millions.
Delhi's chief minister, Atishi Marlena Singh, has announced the closure of all primary schools in the Indian capital due to alarming levels of air pollution. Classes will transition to online formats until further notice as a thick blanket of smog continues to shroud the city and surrounding areas. According to officials, pollution levels in Delhi and neighboring regions have reached hazardous thresholds, with the fine particulate matter levels recorded at over 50 times the World Health Organization's (WHO) safety standards.On Thursday, the Air Quality Index measured an alarming average of 254 micrograms of PM 2.5 per cubic meter of air, far exceeding the WHO's recommended limit of 15. This scale of pollution poses severe health risks, with fine particles capable of entering the bloodstream and affecting vital organs, leading to various cardiovascular and respiratory issues. A recent report indicated that 7.2% of daily deaths in Delhi could be linked to fine particulate pollution.The smog, attributed to a range of factors including low temperatures, smoke from vehicles, dust, and the burning of agricultural stubble, is a recurring annual predicament for the region during winter months. Larger particulate matter also reached alarming levels, with PM 10 averaging 495 micrograms, vastly surpassing WHO safety benchmarks.As residents contend with various health complaints like eye irritation and respiratory difficulties, the government's response has included measures such as dust suppression through road spraying and a ban on non-essential construction. However, critics argue that these strategies have yielded minimal success in mitigating the pollution crisis.While air quality is expected to improve in the days ahead, it will still remain at unhealthy levels. Recently shared satellite images from NASA revealed the extensive smog cloud stretching across northern India and into Pakistan, showcasing the region's dire air quality situation. Earlier this month, officials in Lahore, Pakistan, were also forced to close primary schools due to similar pollution levels.
