Residents of environmental justice (EJ) communities may bear a disproportionate burden of environmental health risk, and often face additional burdens from social determinants of health. Accounting for cumulative risk should include measures of risk from both environmental sources and social determinants. This study sought to better understand cumulative health risk from both social and environmental sources in a disadvantaged community in Texas. Key outcomes were determining what data are currently available for this assessment, clarifying data needs, identifying data gaps, and considering how those gaps could be filled. Analyses suggested that the traditionally defined EJ community in Port Arthur may have a lower environmental risk from air toxics than the rest of the City of Port Arthur (although the entire city has a higher risk than the average for the state), but may have a larger burden from social determinants of health. However, the results should be interpreted in light of the availability of data, the definitions of community boundaries, and the areal unit utilized. Continued focus on environmental justice communities and the cumulative risks faced by their residents is critical to protecting these residents and, ultimately, moving toward a more equitable distribution and acceptable level of risk throughout society.

环境正义 (EJ) 社区的居民可能承受不成比例的环境健康风险负担，并且经常面临健康的社会决定因素带来的额外负担。对累积风险的核算应包括对来自环境来源和社会​​决定因素的风险的衡量。这项研究旨在更好地了解德克萨斯州弱势社区的社会和环境来源的累积健康风险。主要成果是确定目前可用于该评估的数据、阐明数据需求、确定数据差距以及考虑如何填补这些差距。分析表明，亚瑟港传统定义的 EJ 社区可能比亚瑟港市的其他地方具有较低的空气有毒物质环境风险（尽管整个城市的风险高于该州的平均水平），但可能有健康的社会决定因素带来的更大负担。但是，应根据数据的可用性、社区边界的定义和使用的面积单位来解释结果。继续关注环境正义社区及其居民面临的累积风险对于保护这些居民并最终在整个社会中实现更公平的分配和可接受的风险水平至关重要。应根据数据的可用性、社区边界的定义和使用的面积单位来解释结果。继续关注环境正义社区及其居民面临的累积风险对于保护这些居民并最终在整个社会中实现更公平的分配和可接受的风险水平至关重要。应根据数据的可用性、社区边界的定义和使用的面积单位来解释结果。继续关注环境正义社区及其居民面临的累积风险对于保护这些居民并最终在整个社会中实现更公平的分配和可接受的风险水平至关重要。
