Mercury in Marine Tetrapod Liver: Comparison of CV-AFS and ICP-MS Techniques

A study comparing cold vapour atomic fluorescence spectrometry (CV-AFS) and inductively coupled plasma mass spectrometry (ICP-MS) for determining mercury in hepatic tissue from marine tetrapods. Detection limits were 0.02 mg kg-1 for ICP-MS and 0.01 mg kg-1 for CV-AFS, with accuracy assessed using TORT-3 certified reference material. The research, authored by Raiza F. da Silva, found significant mercury loss during lyophilization.

Use Cases

• Comparing analytical method performance based on detection limits for mercury quantification.
• Assessing sample preparation effects based on the described comparison of results with and without lyophilization.
• Validating spectrometry techniques based on accuracy assessment using certified reference material analysis.

Strengths

• Detection limits are quantified: 0.02 mg kg-1 for ICP-MS and 0.01 mg kg-1 for CV-AFS.
• Accuracy was assessed using TORT-3 (lobster hepatopancreas) certified reference material.
• The study includes a systematic comparison between two established analytical techniques.
