SOIL CONTAMINATION IN SHAANXI: CHINA'S INDUSTRIAL LEGACY CHALLENGE Shaanxi Province's industrial foundation—coal mining, petrochemicals, and heavy manufacturing—has left documented soil contamination across approximately 16.1% of surveyed agricultural land in the province, significantly above the national average of 8.6%. The "Pure Land Defense Campaign" represents China's systematic response to decades of unregulated heavy metal and organic pollutant accumulation, particularly from legacy sites in the Wei River basin and surrounding coal-industrial zones. Remediation efforts here matter because Shaanxi feeds roughly 120 million people through inter-provincial grain distribution, meaning soil restoration directly impacts food security across central and eastern China. Success in this region establishes a template for remediating contamination in 300+ other Chinese industrial centers built during the 1980s-2000s expansion phase, determining whether China can decouple industrial growth from persistent environmental debt.
