GLRPPR Sector Resource: The PBT Profiler

The PBT Profiler

The PBT Profiler was designed to be an easy to use, widely available, no-cost tool to screen chemicals lacking experimental data in order to help identify pollution prevention (P2) opportunities. It is a continuation of the Office of Pollution Prevention and Toxics (OPPT, U.S. Environmental Protection Agency) Pollution Prevention (P2) Assessment Framework - a collection of screening models and methods to help promote the design, development, and application of safer chemicals and processes. The P2 Framework uses computerized methods, such as structure/activity relationships (SARs) and standard scenarios, to predict risk related data (physical/chemical properties, bioconcentration, environmental fate, carcinogenicity, toxicity to aquatic organisms, worker and general population exposure, and other information) on chemicals lacking experimental data. The PBT Profiler uses a subset of P2 Assessment Framework computer-based tools to help identify chemicals that potentially may persist, bioaccumulate, and be toxic to aquatic life, i.e., PBT chemicals.

The PBT Profiler was developed jointly by EPA, The American Chemistry Council, The Chlorine Chemistry Council, The Synthetic Organic Chemical Manufacturers Association and with the support and contributions of Environmental Defense.
