sci.risk-assessment-USEPA Calculator
Calculates cancer risk from chronic exposure using USEPA risk assessment framework: Risk = CDI × CSF, where CDI is chronic daily intake and CSF is cancer slope factor. Acceptable risk level: 10⁻⁶ (one excess cancer per million) — arsenic in drinking water at 10 µg/L has risk ≈ 3 × 10⁻⁴, 300× the EPA target.
Inputs
Intake Mg Kg Day
Reference formula or conversion factor shown for context.
Csf Per Mg Kg Day
A multiplier applied in the calculation.
Rfd Mg Kg Day
Amount of medication administered per period. Most dosing is weight-based — verify with a licensed prescriber before clinical use.
Results
incremental lifetime cancer risk ILCR
Overall risk level based on the computed score or classification. Higher risk may call for mitigating actions or additional review.
hazard quotient HQ (non-cancer)
Sample size or count used in the calculation.
cancer risk assessment
Overall risk level based on the computed score or classification. Higher risk may call for mitigating actions or additional review.
ILCR = CDI × CSF
Reference formula or conversion factor shown for context.
non-carcinogenic status
Current state of the system, process, or metric — typically pass/fail, healthy/warning/critical, or a descriptive classification.
risk management
Overall risk level based on the computed score or classification. Higher risk may call for mitigating actions or additional review.
