Overview

High precision analysis of low Pb concentrations in wet deposition samples from Japan, indicating effective extraction methods.

Key Points

  • To analyze low Pb concentration in wet deposition samples from remote areas using advanced techniques.
  • Conducted Pb isotope ratio analysis using multi-collector inductively coupled plasma mass spectrometry.
  • Employed solid phase extraction for sample preparation.
  • Collected samples from mountainous regions in Japan.
  • Pb concentrations ranged from 0.0020 to 1.94 μg L-1.
  • Findings compare the concentrations to those found in Antarctic snow.
