Decadal mercury trends from Schrenk spruce (Picea schrenkiana) needles in the Middle Tianshan Mountains, Northwestern China: Evidence of declining industrial emissions and a rising regional background
Key Points
Mercury trends in needles indicate a decline over the past decade, reflecting changes in emissions.
The analysis revealed a significant drop of approximately 35% in mercury levels in the region.
Environmental monitoring of Picea schrenkiana provides crucial evidence of industrial activity fluctuations.
This study highlights the importance of continuous monitoring to assess environmental health and policy effectiveness.
