Dust from roads and construction sites could be contributing to elevated particulate pollution across Mumbai, with 13 of 14 air quality monitoring stations recording annual average PM10 levels above the national limit in 2025-26.
Winter is yet to set in, but Kolkata has already exceeded its annual PM10 pollution level ... They calculated the cumulative PM10 concentration recorded since Jan 1 and divided it by 365 days.
Around 88% of the readings, or 156 entries, also crossed 100 µg/m³, the national 24-hour limit.“The fact that all cities in Haryana have exceeded the annual PM10 standard for five consecutive years points to a systemic pollution problem.
This year’s crossing was earlier than in four of the previous five years, though later than in 2024.An overshoot day is calculated by tracking cumulative daily PM10 concentrations and dividing the total by 365.
Delhi’s PM10 levels surpassed India’s annual standard of 60 micrograms per cubic metre on April 9, nearly six months before the start of the winter season, according to Centre for Research on Energy and Analysis (CREA).
