Delhi records lowest May PM2.5 levels since 2015, but PM10 levels remain steady

Delhi saw its lowest May PM2.5 levels since 2015, with 54 µg/m³. However, PM10 levels stayed steady at 175 µg/m³. Experts said "PM2.5 has been the lowest this year largely because of meteorological conditions." This suggests rain cleared finer pollutants, but coarser particles persist.
