Navaretnam et al. 2025 — Arsenic Speciation in White and Brown Rice
Summary
This 2025 original-research paper by Navaretnam and colleagues (multiple Malaysian institutions including Universiti Putra Malaysia) presents an improved HPLC-ICP-MS analytical method for quantifying arsenite (As(III)), arsenate (As(V)), dimethylarsinic acid (DMA), and monomethylarsonic acid (MMA) in white and brown rice samples, with a method retention time under 4 minutes. The paper combines the methodological advance with a health risk assessment based on measured rice arsenic concentrations. It is one of the recent primary references for inorganic arsenic concentration in rice samples and supports the rice ingredient page contamination_profile population.
