Overview
Boiteau and colleagues characterized natural nickel- and copper-binding ligands in Eastern Pacific seawater along the US GEOTRACES transect. This is in-scope lane a3 aquatic pathway evidence and not infant-formula occurrence evidence.
Key numbers
The paper reports marine nickel and copper ligand characterization across the transect and notes that dissolved ligand concentrations exceeded dissolved nickel concentrations across the section by a factor of 1.6-12, with results summarized in Table 1.
The methods used 1000 ppm metal reference standards, FT-ICRMS with sub-ppm mass-measurement accuracy, and ICP-MS / voltammetric workflows described throughout the methods section.
Methods (brief)
The study combined chromatographic separation, high-resolution mass spectrometry, voltammetry, and marine-sample collection from the US GEOTRACES Eastern Pacific Zonal Transect. The focus is dissolved marine-metal speciation and ligand structure, not food or formula matrices.
