先前的研究发现，一些地区的低社会经济地位（SES）人口和少数民族居住在危险化学品暴露不成比例的社区。本研究的目的是评估社会人口特征的相关性，对存在的有毒物质释放清单（TRI）设施，空气释放，并在20个县亚特兰大大都会统计区（MSA）的空气质量投诉的患病率和解决方案。我们发现，在TRI设施所在的人口普查区，少数民族居民增加了4.7%。拥有大学学位的女性每增加1%，TRI设施存在的优势比（OR）为0.89（p < 0.01），收入为22，000美元至55，000美元的家庭为2.4（p < 0.01）。与具有大学学位的女性人口相关的每次释放的化学物质排放量的估计减少量为18.53磅（p < 0.01）。在西班牙裔人口较多的人口普查区，投诉需要更长时间才能解决（OR = 1.031，95% CI：1.010-1.054）。总体而言，结果表明，SES和种族/民族与亚特兰大地区的TRI机构选址，发布和投诉有关。这些发现以前没有记录，表明社会经济地位较低和非白人社区可能受到不成比例的影响。
Prior research has found that low socioeconomic status (SES) populations and minorities in some areas reside in communities with disproportionate exposure to hazardous chemicals. The objectives of this study were to evaluate the relevance of socio-demographic characteristics on the presence of Toxic Release Inventory (TRI) facilities, air releases, and prevalence and resolution of air quality complaints in the 20-county Atlanta Metropolitan Statistical Area (MSA). We found that there were 4.7% more minority residents in census tracts where TRI facilities were located. The odds ratio (OR) for the presence of a TRI facility was 0.89 (p < 0.01) for each 1% increase of females with a college degree and 2.4 (p < 0.01) for households with an income of $22,000–$55,000. The estimated reduction in the amount of chemicals emitted per release associated with population of females with a college degree was 18.53 pounds (p < 0.01). Complaints took longer to resolve in census tracts with higher Hispanic populations (OR = 1.031, 95% CI: 1.010–1.054). Overall, results indicate that SES and race/ethnicity are related to TRI facility siting, releases, and complaints in the Atlanta area. These findings have not been documented previously and suggest that lower SES and non-White communities may be disproportionately exposed.
