基于SEFA方法的区域多污染场地土壤修复环境足迹分析
Environmental footprint analysis of regional soil remediation at multiple contaminated sites using the SEFA method
摘要
Abstract
Assessing the environmental footprint of contaminated sites on a regional scale is a relatively underexplored yet crucial area in environmental studies.This study focuses on a central city in the Beijing-Tianjin-Hebei region.Based on the definition of evaluation boundaries and the development of a data inventory,we utilized the widely recognized environmental footprint analysis tool,SEFA,to conduct a quantitative assessment.The results show that the remediation activities at eight priority polluted sites led to a total consumption of 1.8×104 tons of materials and reagents,while the total waste disposal was 1.2×105 tons.The total water usage reached 3.3× 104 m3,and total energy consumption amounted to 1.4×109 MJ.The total emissions of NOx,SOx,and PM were 68.5 tons,with hazardous air pollutant emissions totaling 0.7 tons and greenhouse gas(GHG)emissions amounting to 1.1×104 tCO2e.The GHG emission intensity was 140.1 kgCO2e·m-3,with 84％of the GHG emissions arising from the material and reagent usage phase.These findings provide valuable insights for the green and sustainable remediation of multiple polluted sites in the region.关键词
