Few studies have considered the sociohistorical intersection of environmental injustice and gentrification; a gap addressed by this case study of Seattle, Washington. This study explored the advantages of integrating air toxic risk screening with gentrification research to enhance proximity and health equity analysis methodologies. It was hypothesized that Seattle's industrial air toxic exposure risk was unevenly dispersed, that gentrification stratified the city's neighborhoods, and that the inequities of both converged.
Spatial characterizations of air toxic pollution risk exposures from 1990 to 2007 were combined with longitudinal cluster analysis of census block groups in Seattle, Washington, from 1990 to 2000.
A cluster of air toxic exposure inequality and socioeconomic inequity converged in 1 area of south central Seattle. Minority and working class residents were more concentrated in the same neighborhoods near Seattle's worst industrial pollution risks.
Not all pollution was distributed equally in a dynamic urban landscape. Using techniques to examine skewed riskscapes and socioeconomic urban geographies provided a foundation for future research on the connections among environmental health hazard sources, socially vulnerable neighborhoods, and health inequity.
很少有研究考虑环境不公正和 gentrification 的社会历史交集；本研究以华盛顿西雅图为例，弥补了这一空白。本研究探讨了将空气有毒风险筛选与 gentrification 研究相结合，以增强接近度和健康公平性分析方法的优势。假设西雅图的工业空气有毒暴露风险分布不均，gentrification 使城市社区分层，两者的不平等现象趋同。
将 1990 年至 2007 年的空气有毒污染风险暴露的空间特征与 1990 年至 2000 年华盛顿西雅图的人口普查街区组的纵向聚类分析相结合。
在西雅图中南部的一个地区，空气有毒暴露不平等和社会经济不平等的集群趋同。少数族裔和工人阶级居民更集中在西雅图最严重工业污染风险附近的同一社区。
在动态城市景观中，并非所有污染都均匀分布。使用技术来检查倾斜的风险景观和社会经济城市地理为研究环境健康危害源、社会脆弱社区和健康不平等之间的联系奠定了基础。
