The back seat of a taxi is one of the worst places to be for exposure to ultrafine particulate pollution, a new study has revealed.

People on buses and those riding bikes are also exposed to a lot of the pollutant, while pedestrians and, ironically, those in private cars, are exposed to the least.

Researchers from Imperial College London, UK, tracked exposure to fine particulate pollution second by second as volunteers travelled around a test area along a stretch of Marylebone Road, a busy street in the city.

The researchers were interested in exposure to particles under 100 nanometres in diameter. Some studies suggest that ultrafine particles might pose an especially serious health hazard, and that brief exposures to high levels of particles might be more important than lower exposure over a longer period.
