为了解决与环境空气污染相关的种族/少数民族群体健康风险的差异，本研究在可疑的空气污染热点-滨水区南村（WFS）和城市参考社区-新泽西州卡姆登的Copewood/Davis街道（CDS）社区中描述了个人和环境挥发性有机化合物（VOCs）的浓度。这两个地方都是少数民族为主的贫困社区。在2004-2006年夏季和冬季，我们收集了54名WFS居民和53名CDS居民的24小时综合个人空气样本，其中一个样本在工作日，一个在周末。个人空气采样时，同时采集各社区中心的环境空气样本。WFS中甲苯、乙苯和二甲苯（TEX）的环境含量高于CDS (p < 0.05)，特别是在工作日。与CDS相比，WFS中MTBE和TEX的个人浓度和环境浓度之间存在更强的相关性。个人甲基叔丁基醚、己烷、苯和特克斯含量变化的14%到42%可以解释为当地室外空气污染。这些观察结果表明，当地来源影响了WFS的社区空气污染和个人暴露。当地排放的两种挥发性有机化合物苯和乙苯造成的癌症风险，以及己烷、苯、甲苯和二甲苯造成的非癌症神经系统和呼吸系统影响，在这两个社区都超过了美国环保署的风险基准。这些调查结果强调，需要解决与环境空气污染有关的社会经济弱势群体的健康风险差异问题。该研究还表明，与WFS相似的空气污染热点可以为研究环境空气污染对健康的影响提供稳健的环境。
To address disparities in health risks associated with ambient air pollution for racial/ethnic minority groups, this study characterized personal and ambient concentrations of volatile organic compounds (VOCs) in a suspected hot spot of air pollution – the Village of Waterfront South (WFS), and an urban reference community – the Copewood/Davis Streets (CDS) neighborhood in Camden, New Jersey. Both are minority-dominant, impoverished communities. We collected 24-h integrated personal air samples from 54 WFS residents and 53 CDS residents, with one sample on a weekday and one on a weekend day during the summer and winter seasons of 2004–2006. Ambient air samples from the center of each community were also collected simultaneously during personal air sampling. Toluene, ethylbenzene, and xylenes (TEX) presented higher (p < 0.05) ambient levels in WFS than in CDS, particularly during weekdays. A stronger association between personal and ambient concentrations of MTBE and TEX was found in WFS than in CDS. Fourteen to forty-two percent of the variation in personal MTBE, hexane, benzene, and TEX was explained by local outdoor air pollution. These observations indicated that local sources impacted the community air pollution and personal exposure in WFS. The estimated cancer risks resulting from two locally emitted VOCs, benzene and ethylbenzene, and non-cancer neurological and respiratory effects resulting from hexane, benzene, toluene, and xylenes exceeded the US EPA risk benchmarks in both communities. These findings emphasized the need to address disparity in health risks associated with ambient air pollution for the socio-economically disadvantaged groups. This study also demonstrated that air pollution hot spots similar to WFS can provide robust setting to investigate health effects of ambient air pollution.
