Laser-induced breakdown spectroscopy (LIBS) was applied for detection and quantification of lead in contaminated soils. The paper develops LIBS as a rapid, field-deployable method for soil Pb monitoring. Relevant as a supply-chain monitoring tool for agricultural soils where crop Pb uptake is a concern.
Key numbers
- LOD, calibration model, and measurement performance in full paper.
- Soil Pb concentrations: see full paper for specific values.
Methods (brief)
LIBS for total elemental Pb analysis in soil matrix. Not speciated. Field-relevant method.
Implications
Certification: Supply-chain context for Pb in soil as a driver of crop contamination. Courses: Demonstrates LIBS as a rapid non-destructive method for soil quality monitoring.
