We assessed spatial disparities in the distribution of Toxic Release Inventory (TRI) facilities in Charleston, SC.
We used spatial methods and regression to assess burden disparities in the study area at the block and census-tract levels by race/ethnicity and socioeconomic status (SES).
Results revealed an inverse relationship between distance to TRI facilities and race/ethnicity and SES at the block and census-tract levels. Results of regression analyses showed a positive association between presence of TRI facilities and high percentage non-White and a negative association between number of TRI facilities and high SES.
There are burden disparities in the distribution of TRI facilities in Charleston at the block and census-tract level by race/ethnicity and SES. Additional research is needed to understand cumulative risk in the region.
我们评估了南卡罗来纳州查尔斯顿市有毒物质释放清单(TRI)设施分布的空间差异。
我们使用空间方法和回归分析,按种族/民族和社会经济地位(SES)评估研究区域内街区和普查区层面的负担差异。
结果表明,距离 TRI 设施的距离与街区和普查区层面的种族/民族和 SES 呈反比关系。回归分析结果表明,TRI 设施的存在与高比例的非白人呈正相关,而与高 SES 呈负相关。
查尔斯顿的 TRI 设施分布在街区和普查区层面存在负担差异,按种族/民族和 SES 划分。需要进一步研究以了解该地区的累积风险。
