本研究对居住在新泽西州卡姆登市空气污染热点地区——滨水区南部和Copewood/Davis街道社区的107名居民的时间-地点模式进行了分析。这两个社区的大多数居民都是少数民族和贫困人口。结果表明，就业状况是决定研究人群时间-地点格局的根本因素，不同季节和不同日型的时间-地点格局变化部分归因于就业状况。与全国人类活动模式调查相比，卡姆登队列在户外的时间（3.8小时比1.8小时）明显多于在室内的时间（19.4小时比20.9小时），这表明卡姆登队列暴露于环境空气污染的风险更高。该研究结果对于了解社会经济弱势亚群体的暴露途径和来源具有重要意义，并最终有助于制定有效的策略，以减少“热点”地区社区对环境空气污染的暴露。
This study characterized the time-location pattern of 107 residents living in air pollution hotspots, the Waterfront South and Copewood/Davis Streets communities in Camden, NJ. Most residents in the two communities are minority and impoverished individuals. Results showed that employment status played the fundamental role in determining time-location patterns of this study population, and the variations of time-location pattern by season and by day-type were partially attributed to employment status. Compared to the National Human Activity Pattern Survey, the Camden cohort spent significantly more time outdoors (3.8 hours versus 1.8 hours) and less time indoors (19.4 hours versus 20.9 hours) than the general US population, indicating a higher risk of exposure to ambient air pollution for the Camden cohort. The findings of the study are important for understanding exposure routes and sources for the socioeconomically disadvantaged subgroup and ultimately help develop effective strategies to reduce community exposure to ambient air pollution in "hotspots".
