The Risk Assessment Information System

Step 4: Risk Characterization

The risk characterization step synthesizes all the information gathered in the three previous steps to estimate the likelihood that a hypothetical exposure may adversely impact human health.

  • Review toxicity and exposure assessment output

  • Quantify risks

  • Combine risks across all pathways

  • Assess & present uncertainties

  • Consider site-specific human studies, if available

  • Summarize & present baseline risk assessment characterization results
