ABC’s of PCB’s

“In A Near Nature but Not So Perfect Situation”

  • So many PCB’s!

  • Global production - 1930’s - 1980’s

  • Greater than 1.5 Million Tons

  • U.S. Production 600,000 Tons

  • 1970’s – 1980’s Initiating Controls on PCB’s

  • Spokane River Standards:

    • 170 parts per Quadrillion for Ecology

    • 3.37 parts per Quadrillion for Spokane Tribe


Transport into the environment
Transport Into the Environment

  • PCB’s have a low vapor pressure allowing water to Dissolve PCB’s

  • PCB’s have an ability to grasp particles

  • Air transportation of PCB’s especially those simpler forms with/1-4 chlorine atoms

  • Ventilation of PCB’s containing air from buildings
