Overview

Randomized trial assesses heavy metal risks in glacier basin waters, indicating low ecological hazards.

Key Points

  • This research aims to analyze the distribution and sources of heavy metals in surface waters from a glacier basin.
  • Conducted a comprehensive analysis of heavy metals in surface water samples from Meili Snow Mountains glacier basin.
  • Utilized principal component analysis to group heavy metals and identify source contributions.
  • Performed risk assessments to evaluate ecological and non-carcinogenic risks for different age groups.
  • Heavy metal concentrations were higher in glacier meltwater (0.00300–33.4 μg/L) than downstream rivers (0.00500–2.85 μg/L).
  • Risk assessments revealed low ecological risks (ERI < 150) and non-carcinogenic risks (HI < 1), with children more susceptible than adults.
  • Acceptable carcinogenic risks (TCR: 10−6–10−4), though ingestion of As and Ni posed higher risks, especially in the Yubeng River basin.
