Many environmental justice studies have sought to examine the effect of residential segregation on unequal exposure to environmental factors among different social groups, but little is known about how segregation in non-residential contexts affects such disparity. Based on a review of the relevant literature, this paper discusses the limitations of traditional residence-based approaches in examining the association between socioeconomic or racial/ethnic segregation and unequal environmental exposure in environmental justice research. It emphasizes that future research needs to go beyond residential segregation by considering the full spectrum of segregation experienced by people in various geographic and temporal contexts of everyday life. Along with this comprehensive understanding of segregation, the paper also highlights the importance of assessing environmental exposure at a high spatiotemporal resolution in environmental justice research. The successful integration of a comprehensive concept of segregation, high-resolution data and fine-grained spatiotemporal approaches to assessing segregation and environmental exposure would provide more nuanced and robust findings on the associations between segregation and disparities in environmental exposure and their health impacts. Moreover, it would also contribute to significantly expanding the scope of environmental justice research.
许多环境正义研究试图考察居住隔离对不同社会群体间环境因素不平等暴露的影响，但对于非居住环境中的隔离如何影响这种差异却知之甚少。基于对相关文献的综述，本文讨论了传统的基于居住地的方法在环境正义研究中考察社会经济或种族/民族隔离与不平等环境暴露之间关联时的局限性。它强调，未来的研究需要超越居住隔离，要考虑人们在日常生活的各种地理和时间背景下所经历的全方位隔离。伴随着对隔离的这种全面理解，本文还强调了在环境正义研究中以高时空分辨率评估环境暴露的重要性。成功整合全面的隔离概念、高分辨率数据以及用于评估隔离和环境暴露的精细时空方法，将为隔离与环境暴露差异及其健康影响之间的关联提供更细致入微且有力的研究结果。此外，这也将极大地有助于扩大环境正义研究的范围。
