UK urban air pollution hits 'very high' as fog traps fireworks emissions

Air pollution reached 'very high' levels at 11 UK monitoring sites, mainly in London and Greater Manchester, after a weekend of fireworks and bonfires combined with foggy, still conditions trapped particulate matter. The event is a localized air-quality episode rather than a systemic shift, but it highlights the vulnerability of urban areas to emission accumulation under stagnant weather. The health impact is immediate but likely short-lived as weather patterns change.
