Soil contamination type identification dataset

Soil contamination can be harmful to the ecosystem and humans. Rapid identification of soil contamination types is vital for targeted soil remediation, prevention, and sustainable development of agriculture. This dataset contains raw LIBS spectral data for four types of contaminated soils (heavy metal- contaminated soils, oil-contaminated soils, fertilizer-contaminated soils, clean soils). These soil samples are from eight regional soils from seven major geographical regions in China (Northeast China, North China, East China, Central China, South China, Northwest China, Southwest China, ) respectively.
