PBT pollutants are chemicals that are toxic, persist in the environment and bioaccumulate in food chains and, thus, pose risks to human health and ecosystems. The biggest concerns about PBTs are that they transfer rather easily among air, water, and land, and span boundaries of programs, geography, and generations.
Annual Accomplishments Reports
The third in the annual series, "Breaking the Cycle - PBT Program Accomplishments Report 2001-2002" outlines the successful actions and ongoing investments by EPA's PBT Program. This report describes successes of the PBT Program that cut across a broad spectrum of activities including pollution reductions; filling PBT data gaps; collaborative efforts with private, governmental and international partners; and developing further strategic approaches for reducing releases and exposures to priority PBTs.
The Second Annual Edition of the EPA's Agency-wide Multimedia Persistent, Bioaccumulative, and Toxic Pollutants effort, the 2000 PBT Program Accomplishments Report [PBT] is available online. (1,700 KB)
The 2000 accomplishments report is organized around 4 primary goals:
- preventing the introduction of new PBTs into the marketplace
- reducing risk to human health and the environment from exposure to priority PBTs already in the environment
- halting the transfer of PBTs among air, water and land
- assessing PBTs long-term effect on the environment.
