Pedestrian exposure to air pollution along a major road etc

Pedestrian exposure to PM 2.5, the loss of reflectance (‘blackness’) of the PM 2.5 filters, ultrafine particle counts and carbon monoxide (CO) was investigated along a major road running through the DAPPLE study site in Central London, UK. During an intensive 12-day exposure measurement campaign, groups of four volunteers sampled twice in the morning and twice in the afternoon along Marylebone Road.
