Chemical Safety & Toxicology Assessment
Toxicity assessment : identify the chemical, check known hazards (GHS, IARC), then look for ADMET predictions. Dose makes the poison — always consider exposure level, as a compound that is toxic at high doses may be safe at relevant exposures. Distinguish between acute toxicity (LD50, GHS category) and chronic hazards (carcinogenicity, endocrine disruption) — they require different risk management approaches. Computational predictions (ADMETAI) are T3 evidence and must be anchored by experimental data from PubChemTox or FDA labels wherever available. When evidence conflicts between prediction and experiment, always defer to the experimental finding.
LOOK UP DON'T GUESS : never assume GHS categories, IARC classification, or CTD disease links — always call PubChemTox and CTD tools to retrieve current classifications before reporting.
Comprehensive chemical safety analysis integrating predictive AI models, curated toxicogenomics databases, regulatory safety data, and chemical-biological interaction networks.
When to Use This Skill
Triggers :
"Is this chemical toxic?" / "Assess the safety profile of [drug/chemical]"
"What are the ADMET properties of [SMILES]?"
"What genes does [chemical] interact with?" / "What diseases are linked to [chemical] exposure?"
"Drug safety assessment" / "Environmental health risk" / "Chemical hazard profiling"
Use Cases :
Predictive Toxicology : AI-predicted endpoints (AMES, DILI, LD50, carcinogenicity, hERG) via SMILES
ADMET Profiling : Absorption, distribution, metabolism, excretion, toxicity
Toxicogenomics : Chemical-gene-disease mapping from CTD
Regulatory Safety : FDA label warnings, contraindications, adverse reactions
Drug Safety : DrugBank safety + FDA labels combined
Chemical-Protein Interactions : STITCH-based interaction networks
Environmental Toxicology : Chemical-disease associations for contaminants
COMPUTE, DON'T DESCRIBE When analysis requires computation (statistics, data processing, scoring, enrichment), write and run Python code via Bash. Don't describe what you would do — execute it and report actual results. Use ToolUniverse tools to retrieve data, then Python (pandas, scipy, statsmodels, matplotlib) to analyze it.
KEY PRINCIPLES
Report-first approach - Create report file FIRST, then populate progressivelyTool parameter verification - Verify params via get_tool_info before calling unfamiliar toolsEvidence grading - Grade all safety claims by evidence strength (T1-T4)Citation requirements - Every toxicity finding must have inline source attributionMandatory completeness - All sections must exist with data or explicit "No data" notesDisambiguation first - Resolve compound identity (name -> SMILES, CID, ChEMBL ID) before analysisNegative results documented - "No toxicity signals found" is data; empty sections are failuresConservative risk assessment - When evidence is ambiguous, flag as "requires further investigation"English-first queries - Always use English chemical/drug names in tool calls
Evidence Grading System (MANDATORY) Tier Symbol Criteria Examples T1 [T1] Direct human evidence, regulatory finding FDA boxed warning, clinical trial toxicity T2 [T2] Animal studies, validated in vitro Nonclinical toxicology, AMES positive, animal LD50 T3 [T3] Computational prediction, association data ADMET-AI prediction, CTD association T4 [T4] Database annotation, text-mined Literature mention, unvalidated database entry
Evidence grades MUST appear in: Executive Summary, Toxicity Predictions, Regulatory Safety, Chemical-Gene Interactions, Risk Assessment.
