In brief
Delhi's deteriorating air quality has led schools to adopt hybrid learning methods for primary students, banning non-essential construction activities. With PM2.5 levels soaring to 438, nearly 30 times the WHO's safe limit, authorities have introduced more stringent anti-pollution measures, including limiting vehicle movements. The situation has sparked protests and political disputes over air quality management, with calls for a public health emergency.
Schools in Delhi have been instructed to implement hybrid classes for primary students as the city grapples with escalating air pollution. Authorities have also banned non-essential construction activities in response to worsening air quality.
On Tuesday, stricter anti-pollution measures were enforced, which included restricting the movement of goods carriers in and around the capital. Delhi's air quality has plummeted to 'severe' levels, posing health risks even to healthy individuals and severely affecting those with pre-existing conditions.
Recent data from the Central Pollution Control Board reported PM2.5 levels reaching an alarming 438, indicating dangerous concentrations of fine particulate matter in the air that can lead to respiratory issues.
This figure is nearly 30 times higher than the World Health Organization's safe limit and about eight times greater than India's national average, which is a serious cause for concern as the WHO maintains that a safe 24-hour average should not exceed 15.
Doctors have cautioned especially vulnerable groups—including children and the elderly—to limit outdoor activities and to wear protective masks if they must go outside.
The toxic air quality in Delhi is a recurrent issue during winter months, driven by a combination of factors such as stagnant winds, industrial emissions, vehicular exhaust, dropping temperatures, and crop stubble burning from nearby states.
The Delhi government follows a structured Graded Response Action Plan (GRAP) aimed at managing pollution levels. Recently, Stage Three measures were activated, which include bans on mining, stone crushing, and heavy vehicle transport of dust-generating materials.
The worsening air quality prompted public protests last weekend and has ignited political controversy, with opposition leaders accusing the Delhi government of underreporting pollution data and demanding a public health emergency declaration. The ruling Bharatiya Janata Party (BJP) has refuted these claims, asserting their commitment to pollution control. Chief Minister Rekha Gupta emphasized the government's serious efforts while denying any manipulation of air quality data.
