Key Points

To evaluate inductively coupled plasma-mass spectrometry coupled with sedimentation field-flow fractionation for quantifying trace elements in size-fractionated submicrometer particles.
Separated submicrometer (<1 µm) colloidal particulates using sedimentation field-flow fractionation centrifugation.
Introduced fractions via a Babington-type pneumatic nebulizer into an argon inductively coupled plasma-mass spectrometer to measure ion currents.
Characterized suspended matter collected from river surface waters and performed cadmium ion adsorption assays.
Successfully quantified the major, minor, and trace element distributions across distinct submicrometer colloidal size fractions.
Demonstrated trace cadmium adsorption onto suspended sediments to characterize trace metal-particle interactions in natural aquatic systems.
