Report from the Harbor Consortium of the NY Academy of Sciences
Summary by: M. L. Anderson
A device that converts power generators low-voltage electricity to higher voltage levels for transmission to the load center (a city).
A passive electronic component used to store energy within an intrinsic electrostatic field.
Plasticizer in resins and rubber
Wax extenders (including ceramic molds)
Carbonless copy paper
Heat transfer systems
Sealants / caulking materialMonsanto (US) manufactured PCBs under the name “Aroclor”
PCB fluid was totally enclosed within the electrical equipment (transformers, capacitors and small capacitors in refrigerators, air conditioners, microwave ovens and ballasts.)
PCBs were used as insulating material, flame-retardant materials or as coolants and lubricants.
Hydraulic fluids in underground pumps and mining operations.
Also as compressors in gas pipelines.
A fine mist of PCBs contaminated oils was sprayed in underground metal gas pipes to retard corrosion.More Industrial and commercial usage of PCBs.
1966 - First study that identified PCBs in the environment.
No updated data on:
Passage of the Clean Water Act 1972 Resulted in:
Prohibition on production, distribution and commercialization of PCB’s in 1978.
Superfund legislation was enacted to address previously contaminated sites.
In 1976 Congress enacted the Toxic Substances Control Act (TSCA) to identify and control toxic chemical hazards to human health and the environment.
The NRC requires reporting of PCB transformer fires and spills of 1lb. or more.
Create a safer environment for the @ 20 million people that live in the watershed adjacent to the Harbor by:
Where are the PCBs in Harbor sediments, biota and the atmosphere?
Undertaken to understand PCB loadings, inputs to the system.
Loadings and losses are calculated by multiplying concentration by flow rate.
