Lin Lin's dataset provides contamination levels for heavy metals, pesticides, and mycotoxins in 42 types of traditional Chinese medicine formula granules (TCMFGs). The data includes detection rates and results from a three-dimensional risk assessment framework (HI-P-CV). It was last updated on 2026-05-28.
Use Cases
- Assessing cumulative dietary risk from contaminants based on hazard index (HI) values.
- Identifying high-risk TCMFG varieties based on the 18 flagged varieties.
- Monitoring contamination patterns based on medicinal plant part (aerial vs. underground).
- Evaluating the prevalence of banned pesticides and plant growth regulators.
- Comparing contamination variability across heavy metals, pesticides, and mycotoxins using coefficient of variation (CV) values.
Strengths
- Covers 42 distinct types of traditional Chinese medicine formula granules.
- Reports detection rates for 7 heavy metals, 143 pesticides, and 57 mycotoxins.
- Includes a three-dimensional risk assessment model output (HI, P, CV values).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The dataset is small (33.6 KB), indicating limited scope.
Provenance
- Source
- Lin Lin via figshare.
- Collection Method
- Contaminants were determined by inductively coupled plasma mass spectrometry (ICP-MS), high-performance liquid chromatography tandem mass spectrometry (HPLC-MS) and gas chromatography tandem mass spectrometry (GC-MS).
