Dermal Exposure Calculator (RAGS USEPA)
Estimate dermal exposure dose from water and soil following the RAGS USEPA Part E methodology, including skin permeability coefficient (Kp) and contact surface area.
Overview
This calculator estimates the dermal exposure dose from environmental chemicals such as those in water and soil, following the USEPA Risk Assessment Guidance for Superfund (RAGS) Volume I: Human Health Evaluation Manual, Part E — Supplemental Guidance for Dermal Risk Assessment. Its output is the fundamental input for assessing non-carcinogenic (Hazard Quotient) and carcinogenic (Cancer Risk) risk from direct contact.
What you will learn
- Estimate dermal dose from water and soil

Who it is for
Environmental health and occupational health practitioners, students, and researchers assessing dermal exposure via water or soil.
Prerequisites: No prerequisites. A background in environmental health helps.

Questions about this product
How does it differ from the MoH EHRA calculator?
This one covers the dermal pathway using RAGS USEPA Part E. The MoH EHRA calculator covers the inhalation and ingestion pathways.
