Human Health Risk Assessment (HHRA) Services

November 08, 2022
Roux's team of toxicologists, industrial hygienists, and human health risk assessors have evaluated complex exposure, toxicity, and risk assessment in the context of product safety evaluations, occupational exposure, contaminated site investigation and cleanup, and in toxic tort litigation. Our human health risk assessors guide efficient cleanup of contaminated sites via creative technical approaches to exposure unit/land use assumptions, background contributions, historic fill, and statistical approaches under various regulatory regimes across the United States.

Roux also provides qualitative and quantitative industrial hygiene assessments for commercial and industrial clients in various industries to assist them with both complex and regulatory challenges. Our services include guiding clients through product regulatory testing and compliance and identifying additional potential product exposure hazards.
