    兰州市代表性城区居民时间活动模式调查

    Time-activity Patterns among Residents in Representative Urban Areas of Lanzhou City

      摘要
    • 摘要:
      目的 了解兰州市居民时间活动模式，为精确评估城市大气污染对居民健康的影响提供依据。
      方法 于2016年10-11月，选取兰州市代表性生活与工业城区共709户1 727名常住居民开展问卷调查，分析不同城区、性别、年龄、文化程度、职业特征居民活动模式的差异，并估算其居室内甲醛致癌风险。
      结果 兰州市成年居民10-11月工作日、休息日总室内活动时间分别为1 239和1 275 min/d，总室外活动时间分别为136和102 min/d，交通时间分别为65和63 min/d。男性及技术工人室外时间较长，老年人及离退休人员在家时间较长，服务人员和办公人员室内工作时间较长，中青年人及技术工人交通出行时间较长。成年男性居室内甲醛致癌风险为3.51×10-4，成年女性为3.41×10-4，均超过1.00×10-6安全限值。
      结论 大气污染健康风险评价及防控工作要结合不同地区、不同特征人群的时间活动模式，以提高评价的精确性和防控的可靠性。

       

      Abstract:
      Objective To investigate the time-activity patterns of representative residents in Lanzhou City, and provide the evidence for accurate assessment of the impact of urban air pollution on residents' health.
      Methods A total of 1 727 residents from 709 households in representative living and industrial urban areas of Lanzhou City were surveyed from October to November in 2016. The differences of time-activity patterns in various urban areas, gender, age, education levels and occupational characteristics were analyzed. Then the carcinogenic risk of formaldehyde in the house was estimated.
      Results The indoor activity time of Lanzhou residents in weekdays and rest days was 1 239 and 1 275 min/d, respectively, the total outdoor activity time was 136 and 102 min/d, respectively, and transportation time was 65 and 63 min/d, respectively. Male and skilled workers spend longer time outdoor than female and others professionals. The elderly and retirees spend more time at home than young people, service staff and office staff have a long indoor working time, young people and skilled workers take a longer time for transportation. The cancer risk probability of formaldehyde was 3.51×10-4 for adult man, 3.41×10-4 for adult woman, both of which exceeded the acceptable level (1.00×10-6).
      Conclusions The time-activity patterns in population of different regions and characteristics should be combined with the health risk assessment and prevention and control of air pollutionh, as well as to improve the accuracy of evaluation and the reliability of prevention and control.
