Human Health Risk Assessment

Evaluating Environmental Data to Determine Potential Health Risks

It is critical to promptly and accurately assess the extent of exposure and risk associated with contamination following a chemical exposure. CTEH risk assessors evaluate the multiple exposure pathways that are possible at a site and the complex parameters necessary to evaluate any risk from ingestion of contaminated soil, water, or food, inhalation of vapor and particulates, and consideration of absorption of chemicals through skin contact.

Our team conducts risk assessments in accordance with various state, federal, and international risk assessment guidelines (USEPA RAGS, DTSC HERO, TCEQ TRRP, LDEQ RECAP, Health Canada). However, what sets CTEH apart from others is our ability to incorporate unique and innovative strategies to build on the existing risk assessment framework to serve you and your personnel in the most effective way possible. These strategies include:

  • Site-specific exposure assessments
  • Chemical-specific exposure assessments
  • Receptor-specific exposure assessments
  • Job-task-specific exposure assessments
  • Incorporation of bioaccessibility factors into exposure assessments
  • Evaluation of multiple chemicals and biological interactions at target organs
  • Toxicological assessments of chemicals without existing USEPA-derived toxicity factors
  • Derivation of risk-based screening levels for chemicals with no existing standards
