(FUNCTIONAL FLUIDS)
Dear Customer:
Receiitly several newspaper and magazine articles have been
published indicating that Polychlorinated Biphenyls (PCBs)
have been discovered at some points in some marine, aquatic
.
and wildlife environments. The quantities detected are said
to be in the parts per million and parte per billion categories.
It is claimed that the PCBs found strongly resemble chlorinated
biphenyls containing 5*$ and 60# chlorine by weight. Products
which are sold by Monsanto under the trade names of Aroclor
1254 and 1260 do contain chlorinated biphenyls*' In addition
to Aroclor 1254 and 1260/ Monsanto sells certain functional
fluids containing Arocl.ox 1254. These include Pydraul 625,
Pydraul AC, Pydraul AC - Winter. Grade, Pydraul 5^0, Terminol
FR-3 and certain dielectric formulations. Several other
companies around the world also produce products containing
chlorinated biphenyls.

As your supplier of Aroclor 1254 and 1260 and formulated products

2. PCBs with a chlorine content of less than 54$ have not been found in the environment and appear to present no potential problem to the environment.
We haye developed, and are now testing, new formulations to

We feel that all possible care should be taken in the appli tion, processing and effluent disposal of these products to prevent them becoming environmental contaminants. Of interest to you may be an article in Chemical Week, October 29, 19&9 regarding water pollution standards set by each state in the Union. It is attached. This article reflects that good manu facturing practice in the future may require that no products used by any company should find their way into waterways.
