dc.description.abstract | We evaluated personal exposure of 62 individuals to the air pollutant Black Carbon, using 13 portable aethalometers while keeping detailed records of their time-activity pattern and whereabouts. Concentrations encountered in transport are studied in depth and related to trip motives. The evaluation comprises more than 1500 trips with different transport modes. Measurements were spread over two seasons. Results show that 6% of the time is spent in transport, but it accounts for 21% of personal exposure to Black Carbon and approximately 30% of inhaled dose. Concentrations in transport were 2-5 times higher compared to concentrations encountered at home. Exposure was highest for car drivers, and car and bus passengers. Concentrations of Black Carbon were only half as much when traveling by bike or on foot: when incorporating breathing rates, dose was found to be twice as high for active modes. Lowest 'in transport' concentrations were measured in trains, but nevertheless these concentrations are double the concentrations measured at home. Two thirds of the trips are car trips, and those trips showed a large spread in concentrations. In-car concentrations are higher during peak hours compared to off-peak, and are elevated on weekdays compared to Saturdays and even more so on Sundays. These findings result in significantly higher exposure during car commute trips (motive 'Work'), and lower concentrations for trips with motive 'Social and leisure'. Because of the many factors influencing exposure in transport, travel time is not a good predictor of integrated personal exposure or inhaled dose. (C) 2012 Elsevier Ltd. All rights reserved. | - |
dc.description.sponsorship | Bruno Kochan and Dirk Roox from IMOB are acknowledged for their work on the data collection tool 'PARROTS'; Rob Brabers from VITO for technical assistance with the aethalometers. Black Carbon measurements from the Flemish Environment Agency (VMM) have been used to correct for variations in background concentrations. The authors also wish to thank all test persons for participating in this experiment, and two anonymous reviewers for their suggestions. This study was partly financed by VITO strategic research funds and a VITO scholarship to Evi Dons. | - |
