Why in news
Delhi's AQI hit 261 due to transnational mineral dust from Afghanistan, Iran, and Pakistan, highlighting the transboundary nature of air pollution.
Background
The Commission for Air Quality Management (CAQM) identified mineral dust from Afghan storms as the primary driver for the AQI spike. The air quality reached its highest level since April 17, 2024, without necessitating the immediate invocation of GRAP Stage-I.
