W监测是在英国伦敦的48条路线上同时步行和驾车时进行的。2005年5月和6月期间进行了监测。路线长度从601米到1351米不等，大多数路线是双向的。每次步行的车程时间为1.5至15分钟(平均3.7分钟)和7.3至30分钟(平均12.8分钟)；因此，每次步行最多重复5次汽车旅行，并计算路线的平均结果。汽车出行时车窗紧闭，通风系统设置适中。结果表明，步行时的平均暴露量远远超过驾车时的平均暴露量，粗颗粒物质量(PM10-PM2.5)的系数为4.7，细颗粒物质量(PM2.5-PM1)的系数为2.2，极细颗粒物质量(PM2.5-PM1)的系数为1.9(
w Monitoring was carried out of particulate concentrations whilst simultaneously walking and driving 48 routes in London, UK. Monitoring was undertaken during May and June 2005. Route lengths ranged from 601 to 1351 m, and most routes were travelled in both directions. Individual journey times ranged from 1.5 to 15 min by car (average 3.7 min) and 7.3 to 30 min (average 12.8 min) whilst walking; car trips were therefore repeated up to 5 times for each single walking trip and the results averaged for the route. Car trips were made with windows closed and the ventilation system on a moderate setting. Results show that mean exposures while walking are greatly in excess of those while driving, by a factor 4.7 for the coarse particle mass (PM10-PM2.5), 2.2 for the fine particle mass (PM2.5-PM1), 1.9 for the very fine particle mass (
