According to this catalog, highly toxic chemicals refer to chemicals with acute acute toxicity hazards, including synthetic chemicals and their mixtures and natural toxins, as well as acute toxicity that is likely to cause public safety hazards of chemicals.

- Oral LD50 (rat experiment) ≤ 5 mg/kg
- Percutaneous LD50 ≤ 50 mg/kg
- Inhalation (4 hours) LC50 ≤ 100 ml/m³ (gas) or 0.5 mg/L (vapor) or 0.05 mg/L (dust/mist)
