Toxics Release Inventory (TRI) Program

TRI Data and Tools

TRI data are available through a variety of online tools, and through downloadable data files.

Please note the following important information before using TRI data:

  • TRI data reflect the quantities of TRI chemicals that are disposed of, released to the environment, or managed (for example, treated, or recycled). TRI data do not include information about public exposure to chemicals.
  • Release estimates alone are not sufficient to determine exposure or to calculate potential risks to human health and the environment. TRI data, in conjunction with other information, such as the toxicity of the chemical, the release medium (e.g., air), and site-specific conditions, can be used as a starting point in evaluating exposures that may result from releases of toxic chemicals.
 TRI Data and Tools
  • TRI chemicals vary widely in toxicity and have different potential to remain in the environment, so that quantities released or managed by a facility are not always the best indication of whether a chemical may pose harm to humans or the environment. Many facilities limit the contamination and potential human exposure by managing the chemicals in certain ways, e.g., in well designed and managed landfills.

Tools For Data Access And Analysis

myRTK is recommended for all users of TRI data, especially mobile users, as it is an EPA Web application designed for mobile devices. For any location or address, myRTK maps nearby facilities that report to TRI, as well as large permit holders that report to EPA Air, Water or Hazardous Waste programs and are expected to produce, manage or release TRI-reportable chemicals. TRI Comparative Analysis Tool is recommended for TRI data users interested in comparing TRI data with facility-level data from the Agency's Air Facility System (AFS), Permit Compliance System (PCS), Integrated Compliance Information System for the National Pollutant Discharge Elimination System (ICIS-NPDES), and Resource Conservation and Recovery Act Information system (RCRAInfo).

TRI Explorer is recommended for beginner to advanced users of TRI data. This on-line tool generates reports based on facilities, chemicals, geographic areas, or industry type (NAICS code) at the county, state, and national level. It provides information for on- and off-site disposal or other releases, transfers off-site, and other waste management data. Envirofacts is recommended for beginner to advanced users of a wide variety of EPA datasets including TRI. EPA created the Envirofacts Warehouse to provide the public with direct access to information contained in its databases on Air, Chemicals, Facility Information, Grants/Funding, Hazardous Waste, Risk Management Plans, Superfund, Toxic Releases.

TRI.NET is recommended for users who are familiar with TRI data and need a more powerful tool to efficiently analyze the data. It is a downloadable high performance data engine for querying the TRI. This tool supports large and complex queries and trends with interactive drill-downs and ad hoc query capabilities. TRI-CHIP is recommended for the more technical user of TRI data interested in health hazards that TRI chemicals pose to human health. Toxics Release Inventory Chemical Hazard Information Profiles (TRI-CHIP) is a database system containing hazard information for the chemicals on the TRI.

Other data sources and information to consider when using TRI data

EPA's Integrated Risk Information System (IRIS) contains summaries of hazard assessments and EPA regulatory information on over 500 specific chemicals. It is a key source for descriptive and quantitative hazard/risk information, such as oral reference doses and inhalation reference concentrations for chronic, non-carcinogenic health effects; oral slope factors and unit risk for chronic exposure to carcinogens; EPA drinking water health advisories; and summaries of EPA regulatory actions. The system is useful in the risk assessment process.

EPA's Risk-Screening Environmental Indicators (RSEI) is a screening tool developed by EPA that analyzes risk factors to put TRI release data into a chronic health context. RSEI is often used by government regulators, communities, journalists, industry and others to examine trends, identify important emissions situations for follow-up, support community-based projects, and initially screen potential impacts of emissions. Information can be sorted in numerous ways such as by chemical, media, geographic areas, etc.

National Library of Medicine (NLM) TOXNET System Exit EPA Disclaimer makes TRI data and health information accessible to concerned citizens and to businesses and organizations interested in environmental or public health issues. TOXNET offers state-of-the-art, user-friendly, on-line searching.

Agency for Toxic Substances & Disease Registry ToxFAQs(TM) Exit EPA Disclaimer
ToxFAQs is a series of summaries about hazardous substances being developed by ATSDR's Division of Toxicology. Information for this series is excerpted from the ATSDR Toxicological Profiles and Public Health Statements. Each fact sheet serves as a quick and easy to understand guide. Answers are provided to the most frequently asked questions about exposure to hazardous substances found around hazardous waste sites and the effects of exposure on human health.
