Delhi Chokes on Smog: Schools Shift to Hybrid Classes and Mining Halted Amid Hazardous Air
Delhi is facing a severe air crisis, and the measures being taken are a stark reminder of how dangerous pollution has become. Schools in the city have been instructed to adopt hybrid learning for primary students, while non-essential construction work has been put on hold as the air quality continues to deteriorate.
On Tuesday, local authorities rolled out stricter anti-pollution regulations. These include limiting the movement of goods vehicles within the city and its surrounding areas to reduce emissions and dust. The situation is far from normal: Delhi's air quality has now reached "severe" levels, which poses health risks even for healthy individuals and can be extremely harmful for people with existing medical conditions.
On Wednesday, the Central Pollution Control Board recorded PM2.5 levels hitting 438 in Delhi—concentrations of fine particulate matter that are alarmingly high and can deeply penetrate the lungs. To put this in perspective, this level is nearly 30 times above the World Health Organization's safe threshold and about eight times higher than India's national average. According to the WHO, a 24-hour average of 15 is considered safe for human health.
Medical professionals are urging citizens, especially children and the elderly, to stay indoors as much as possible. When going outside is unavoidable, wearing protective masks is strongly recommended.
This isn’t a one-off issue—winter months routinely bring toxic air to Delhi and much of northern India. The causes are multifaceted: low wind speeds trap pollutants, vehicle emissions and industrial activities release harmful particles, falling temperatures worsen the situation, and seasonal crop burning in nearby states adds to the smog.
To tackle the crisis, Delhi enforces the Graded Response Action Plan (GRAP), a series of phased measures aimed at curbing pollution. Stage three of GRAP came into effect on Tuesday, introducing restrictions such as banning mining and stone-crushing activities, and halting the movement of vehicles carrying dust-producing materials.
The worsening air quality has not only impacted daily life but has also triggered public protests and political debates. Over the weekend, citizens voiced their frustrations, and political tensions escalated. Saurabh Bhardwaj of the opposition Aam Aadmi Party (AAP) accused the Delhi government of "manipulating" pollution data and failing to safeguard public health. He argued that despite alleged adjustments to the figures, the air quality remains dangerously high and called for the declaration of a public health emergency.
In response, the BJP-led Delhi government rejected these accusations. Chief Minister Rekha Gupta stated, "Our administration is tackling pollution with utmost seriousness and speed." Environment Minister Manjinder Singh Sirsa explained to Hindustan Times that all air quality data is publicly accessible. He clarified that sprinkling water near monitoring stations was only intended to reduce dust, not to alter readings.
But here's where it gets controversial: can air quality management truly be transparent when multiple stakeholders have competing interests? And how should governments balance economic activity with public health?
