摘要

This study investigated the passenger exposure to particulate matter (PM) in long-distance buses in Taiwan. PM and CO(2) were measured in thirty buses traveling between Taipei and Tainan. The results indicated that average in-cabin PM levels were below the guidelines or standards suggested by Taiwan and other countries. Cigarette smoking ...更多

简介
  • Transportation vehicles are indispensable in daily life.
  • The time spent in transportation vehicles daily may range from several minutes to several hours.
  • In a study of commuters in Taipei, Taiwan, Wu (2005) reported that exposure to PM10, PM2.5, and PM1.0 was highest in those commuting by bus.
  • Short-term exposure to PM is associated with increased hospital admission and mortality for cardiovascular illnesses as well as stroke (Dockery et al, 1993; Downs et al, 2007; Pope and Dockery, 2006; Pope et al, 2002).Given the above findings, more research efforts are needed to clarify the health effects in bus commuters

  • Transportation vehicles are indispensable in daily life
  • The arithmetic means of PM10, PM2.5, and CO2 levels were all lower than the indoor air quality (IAQ) guidelines set by the Taiwan EPA (PM10: 150 lg/ m3 – 24 h; PM2.5: 100 lg/m3 – 24 h; CO2: 1000 ppm – 24 h) (Taiwan Environmental Protection Administration, 2005)
  • This study investigated in-cabin particulate matter (PM) in long-distance buses traveling between two cities along the west coast of Taiwan
  • Levels of particulate matter in long-distance buses countries, which indicates that the potential adverse health effect of people expose to such levels is insignificant
  • Some bus drivers were found to smoke while driving, cigarette smoking revealed no effect on in-cabin PM2.5 level
  • As exposure to high PM level is known to be associated with increased morbidity and mortality (Pope and Dockery, 2006), lowering exposure to in-cabin PM is essential for the health of passengers and especially for bus drivers who frequently work long hours
方法
  • Sampling strategy

    Five bus companies providing passenger transportation service between Tainan City in southern Taiwan and Taipei City in the north were analyzed.
  • Levels of particulate matter in long-distance buses traveling on the highway, drove on local streets again after exiting the highway to get to the terminal.
  • These long-distance buses usually stopped for passenger boarding and alighting while on local streets in the departure and arrival cities, respectively.
  • To obtain values closer to true PM10 and PM2.5 values from DustTrak, all readings from the DustTrak aerosol monitor were calibrated against a model 1400a TEOM

  • Results and discussion

    Levels of in-cabin pollutants

    Table 1 summarizes the hourly average concentrations of PM10, PM2.5, and CO2 obtained for the 30 measurement days, and Figure 1 shows a box-andwhisker plot of the in-cabin PM10, PM2.5, and CO2 to which passengers were exposed as well as relevant regulations or guidelines.
  • The arithmetic means of PM10, PM2.5, and CO2 levels were all lower than the IAQ guidelines set by the Taiwan EPA (PM10: 150 lg/ m3 – 24 h; PM2.5: 100 lg/m3 – 24 h; CO2: 1000 ppm – 24 h) (Taiwan Environmental Protection Administration, 2005).
  • Compared with the guidelines or standards set by Hong Kong (Hong Kong Environmental N AM s.d. GM g.s.d Min PM10 173.
  • Protection Department, 2003), USA (US Environmental Protection Agency, 2008) and World Health Organization (WHO, 2005), the exposure of long-distance bus passengers in Taiwan to PM and CO2 is apparently acceptable
结论
  • Some bus drivers were found to smoke while driving, cigarette smoking revealed no effect on in-cabin PM2.5 level.
  • As exposure to high PM level is known to be associated with increased morbidity and mortality (Pope and Dockery, 2006), lowering exposure to in-cabin PM is essential for the health of passengers and especially for bus drivers who frequently work long hours.
  • Feasible approaches to lowering in-cabin CO2 and PM concentrations include increasing the air exchange rate and installing filters with high PM removal efficiency in ventilation system

  • This study found that in-cabin CO2 level was positively associated with the number of passenger (P < 0.01), i.e. CO2 level increased with the increasing passenger number (Figure 2)
