About Exposure & Risk

Risk is the product of Hazard and Exposure

We must understand the nature of the Hazard and the Exposure 

before we can understand and manage the Risk

 We are experts in human health exposure & risk assessment

Four Step Risk Assessment Process 

  • Hazard Identification – determination of whether exposure to a hazard can cause an increased incidence of an adverse health effect and the characterization of the nature and severity of the effect 

 

  • Dose-response relationship characterization of the relationship between exposure (or dose) and the incidence and severity of the adverse health effect 

 

  • Exposure assessment – determining of the intensity, frequency, and duration of exposures to the hazard 

 

  • Risk characterization – combines the assessments of exposure and response under various exposure conditions to estimate the probability of specific harm to an exposed individual or population.
