Chemical Database

BREEZE Risk Analyst includes a fully editable chemical database providing the flexibility necessary for keeping the database current and complete. The chemical database includes the 204 HHRAP Companion Database chemicals and the necessary fate, transport, and toxicity parameters for evaluating acute exposure, cancer risks, and noncancer hazards. Users can modify parameters based on specific state and regional regulatory requirements or unique site-specific factors. New chemicals can also be added and quickly populated with the necessary fate and transport and toxicity parameters.

Chemical types includes volatiles, semi-volatiles, and metals including:

  • Polychlorinated dibenzo(p)dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)
  • Polynuclear aromatic hydrocarbons (PAHs)
  • Polychlorinated biphenyls (PCBs)
  • Nitroaromatics
  • Phthalates
  • Other organics (e.g., Benzene, Cumene, 1,3-Butadiene)
  • Metals (e.g., Mercury, Lead, Arsenic, Chromium)
