A new method accurately measures acetone in seawater using chemical derivatization and GC/MS analysis. This research provides the first acetone measurements in the North Atlantic and Arctic waters, revealing concentrations up to 9.6 nM.

Area of Science:

  • Environmental Chemistry
  • Oceanography
  • Analytical Chemistry

Background:

  • Acetone is a significant compound influencing atmospheric and oceanic chemistry, impacting the tropospheric HO(x) budget.
  • Understanding acetone's role is crucial due to its environmental and health implications.
  • Accurate measurement of acetone in marine environments is essential for atmospheric-ocean interface studies.

Purpose of the Study:

  • To develop a mobile, sensitive, selective, economical, and facile method for determining acetone concentrations in seawater.
  • To address the challenges posed by seawater's buffering capacity for accurate acetone analysis.
  • To report the first measurements of acetone in the North Atlantic and Arctic Ocean surface waters.

Main Methods:

  • Acetone derivatization to pentafluorobenzyl oxime using 1,2,3,4,5-pentafluorobenzylhydroxylamine (PFBHA).

  • Solid-phase microextraction (SPME) for sample concentration.
  • Gas chromatography/mass spectrometry (GC/MS) for sensitive and selective detection, achieving a 3.0 nM detection limit.

    • Main Results:

    • A robust method was established, overcoming seawater pH challenges by using buffered standards and sample acidification.
    • Acetone concentrations in Nordic seas surface samples ranged from 5.5 to 9.6 nM.
    • These findings represent the initial reported acetone measurements for the far North Atlantic and Arctic waters.

    Conclusions:

    • The developed method offers a practical solution for acetone determination in complex marine matrices.
    • The study provides novel insights into acetone distribution in previously unmeasured polar oceanic regions.
    • Further research can utilize this method to investigate acetone's role in polar atmosphere-ocean exchange processes.
