Air pollution invades London subway

Air quality doesn’t improve in London either. In January, the emission limits of nitrogen oxides established by the WHO (200 µg/m³) were exceeded for 17 hours every day, according to the measurement station at King’s College London. According to a study of the University of Surrey, travelers in the London subway are 8 times more affected by fine particulates than drivers and commuters, since polluted air is sucked in by the subway tunnels. In addition, the rest of the way to the workplace is made by foot and through dirty air.
