中国标准高铁车厢内的pm2.5和二氧化碳暴露量进行了检测。研究发现，0.07mg/m3和1200ppm的浓度受乘客人数、通风系统和车厢等级的显著影响。当车厢内的乘客从10人增加到80人时，乘客呼吸区的浓度会增加0.04mg/m3，并且与空气交换率成反比。车厢内pm2.5浓度最高的车厢是餐车，其他车厢的pm2.5浓度较低，但水平相似。空气周转越快，pm2.5的去除率就越高。
Exposure to PM2.5and CO2inside standard high-speed Chinese rail carriages is examined. The concentrations, 0.07mg/m3and 1200ppm, are found to be significantly affected by passenger numbers, ventilation systems, and the carriage class. As passengers increase from 10 to 80 in a carriage, the concentrations increases by up to 0.04mg/m3in the passenger-breathing zone, and are inversely proportional to the air exchange rate. The greatest in-carriage PM2.5concentration are found in the dinning carriage, with lower but similar levels found in other carriage classes. More rapid air turnover leads to slightly higher PM2.5removal.
