TRI Chemical Toxicity Data and Comparative Analysis

TRI-CHIP allows easy access to toxicity information from multiple data sources for chemicals on the Toxics Release Inventory (TRI) list. This downloadable Microsoft Access database allows you to customize searches across a single chemical, a set of specific chemicals or a TRI chemical category of interest.

Download TRI-CHIP version 2.08.

With TRI-CHIP you can:

• Search toxicity information from multiple data sources for TRI chemicals
• Use built-in queries to identify chemicals that meet quantitative toxicity criteria, such as lowest observed adverse effect levels (LOAEL), above a specified value
• Identify all TRI chemicals associated with a critical adverse human health effect of interest
• Print customized chemical toxicity profile reports
• Readily move in and out of websites containing additional chemical toxicity information

Health hazard information sources available for query are:

• EPA's Integrated Risk Information System (IRIS)
• EPA's Office of Pesticide Programs (OPP) Registration Documents
• Agency for Toxic Substances and Disease Registry (ATSDR)
• Cal/EPA - California Environmental Protection Agency
• National Toxicology Program (NTP) - 12th Report on Carcinogens
• International Agency for Research on Cancer (IARC)
• Toxics Release Inventory (TRI) Federal Register Notices
