Urinary mercapturic acid testing using chromatography is complex and costly. Automation could reduce expenses, making these vital xenobiotic exposure biomarkers more accessible for human biomonitoring.

Area of Science:

  • Analytical Chemistry
  • Environmental Health
  • Biomarker Discovery

Context:

  • Urinary mercapturic acids are key biomarkers for human exposure to xenobiotics.
  • High-performance liquid chromatography (HPLC) and gas chromatography (GC) are established methods for their determination.
  • Current methods often require extensive preliminary sample preparation, such as solid-phase extraction (SPE).

Purpose:

  • To review current analytical techniques for urinary mercapturic acids.
  • To identify limitations in the biomonitoring application of these tests.
  • To explore potential avenues for improving cost-effectiveness and accessibility.

Summary:

  • HPLC and GC coupled with derivatization and sensitive detectors enable mercapturic acid measurement.

  • Sample purification steps like SPE are crucial for accurate analysis.
  • The high cost and complexity currently limit the widespread use of urinary mercapturic acid tests in biomonitoring.

    • Impact:

    • Cost reduction through fully automated systems could enhance the utility of urinary mercapturic acid tests.
    • Increased accessibility of these tests would benefit human biomonitoring and exposure assessment.
    • Further research into automated analytical systems is warranted to overcome current limitations.
