A colorimetric method using amino-1,8-naphthalenediamine (ADA) and Victoria Blue B (VBB) reagents was developed for cadmium detection and applied to actual food samples including rice, milk, and vegetables, reporting real Cd concentrations. This makes the paper a food occurrence study as well as an analytical methods paper. Confirm specific concentration values and sample numbers from the full paper.
Key numbers
- Cd concentrations in rice, milk, and vegetables: see full paper for specific values.
- LOD, linear range, and recovery data in full paper.
- Sample provenance not confirmed at classification stage; see full paper for geographic details.
Methods (brief)
Colorimetric detection using ADA/VBB dye-based reaction. Method compared against standard ICP methods for validation. Measures total dissolved Cd after digestion; not speciated. Real food samples tested rather than spike-recovery only.
Implications
Certification: Contains real Cd occurrence data in rice, milk, and vegetables. Data should be evaluated against ICP reference values reported in the same study for accuracy assessment. Courses: Demonstrates low-cost colorimetric approaches for food Cd monitoring applicable to resource-limited settings. App: Potential Cd occurrence data contribution to rice, milk, and vegetable contamination profiles pending confirmation of specific values and ICP validation correlation.
