- Abstract:
- Estimation of measurement uncertainty of the metal content in different soils was done using validation and quality control data. Precision under within-laboratory reproducibility conditions was estimated from duplicate analysis. Trueness was determined as recovery of the analyte from two certified reference materials (CRM). The CRM properties on the results obtained is critically evaluated.
