农民工是我国城市化和工业化进程加快中的一个特殊弱势群体，他们在污染环境中工作和生活。例如，在电子废物回收领域，移徙工人接触多氯联苯等污染物是非正规电子废物回收过程的结果。对一个外来务工人员聚集的电子垃圾回收区的村庄进行了调查。按照工作地-路上-回家的三个空间转换模拟农民工的日常生活。对农民工住宅、工作场所的室内空气、粉尘和道路环境空气进行采样。外来务工人员所在地空气和粉尘中PCB含量高于当地居民。外来务工人员的健康风险是当地居民的3.8倍。这不仅是由于工作中的接触，而且也是由于他们的活动模式和居住的环境条件。这些结果揭示了外来务工人员与当地居民健康风险差异的原因，同时也表明生活方式和经济状况是相对于职业暴露而言经常被忽视的重要因素。
Migrant workers who work and live in polluted environment are a special vulnerable group in the accelerating pace of urbanization and industrialization in China. In the electronic waste (e-waste) recycling area, for example, migrant workers' exposure to pollutants, such as PCBs (polychlorinated biphenyls), is the result of an informal e-waste recycling process. A village in an electronic waste recycling area where migrant workers gather was surveyed. The migrant workers' daily routines were simulated according to the three-space transition: work place–on the road–home. Indoor air and dust in the migrant workers' houses and workplaces and the ambient air on the roads were sampled. The PCB levels of the air and dust in the places corresponding to the migrant workers are higher than those for local residents. The migrant workers have health risks from PCBs that are 3.8 times greater than those of local residents. This is not only caused by the exposure at work but also by their activity patterns and the environmental conditions of their dwellings. These results revealed the reason for the health risk difference between the migrant workers and local residents, and it also indicated that lifestyle and economic status are important factors that are often ignored compared to occupational exposure.
