The February 27 letter reviewed some of the potential hazards of PCBb and of environmental polution In general. The June 1 letter announced that we were withdrawing all poly chlorinated biphenyls used as plasticizers or raodifiera from the market, and that the last shipment of these materials would be made August 30, 1970. In as much aa you may have some Inventory of these materials which you might be planning to use during the period in which you change over to other products, we felt it impera tive to inform you of the latest information concerning FCBs. It was recently brought to our attention that the Food and Drug Administration has apparently established guidelines setting forth suggested maximum levelB of FCBs allowable in certain foods. These levels, as we understand them, are 5 parts per million in fish and 0*2 parte per million in milk. Monsanto, therefore, strongly recommends that FCBe not be used in applications which could lead, either directly or indirectly, to the contamination of food and water supplies for humans or animals. Examples of appli cations which would seem particularly hazardous would be coatings for water treatment facilities, coatings for food handling equipment, or coatings for suoh farm items as silos and feed hoppers. TOWOLDMON0003457 WATER_PCB-00000479 oI -2- It has recently come to our attention that PCBs have been found In cows milk. This adds emphasis to HocBanto' s re commendation that PCBs not be used In any application where they might come in contact with or otherwise contaminate food, silage, water supplies, eta. The latest available bulletin on our line of Aroclors is enclosed for your use. This publication replaces and supercedes bulletin O/PI^-306 - Aroclor Plasticizers. The only products listed which will be sold after August 31, 1970 are l) Aroclor 1221, a monochlorlnated biphenyl which is readily biodegradable, and 2) AroclorB 5442 and 546o, both chlorinated terphenyls which have not shown themselves to be environmental contaminants. Please pay special atten tion to the section of this bulletin which relates to environmental hazards. In addition to the products listed above which will remain on the market, Monsanto will sell a series of blends of Aroclor 1221 and Aroclor 5460 which will replace the poly chlorinated biphenyls for many applications. During this withdrawal of PCBs from the market, Monsanto has had In effeo.t a modified returned goods policy stating that unopened containers less than one year old could be returned for full credit through July 31, 1970. Prom August 1 through August 31, 1970, 90 percent credit would be allowed. From September 1 through December 31, 1970, 50 percent credit would be allowed. The customer will pay all return freight. All of the dates in the time schedule for this returned goods policy are hereby extended an additional two months............. Monsanto realizes that the removal of these products from the market has caused a great deal of concern and expense for our customers. This is certainly regrettable. However, it appears to us that as a responsible supplier, this is the only reasonable course of action. We stand ready to assist you as we can with your reformulation work. .................. .... /dbw Vpiy/TMpeotfurijy, y> JF Walter E. chalk Director of Sales Plasticizers . |3 i 5 t tI \I !

Solability The unique Arodor plasticizers are among the most versatile chemi cally produced materials available. One outstanding characteristic -- inertness -- makes Aroelor useful in many ways for many different applications. The major benefits offered by Aroelor include: Chemical Resistance Fire Retardsince Compatibility with most resins Nonoxidaticm Adhesivity Law Cost Monsanto's Aroelor plasticizers comprise a series of chlorinated bi phenyls and chlorinated pdyphenyls, They vary from mobile, oily liquids to white crystals and hard, transparent resins. Twelve of the Arodor plasticizers, each of which represents a series, are discussed in this bulletin. An understanding ol the system for designation of each Arodor should prove useful in the evaluation of the property gradations among them. The last two digits indicate the approximate weight percentage of chlorine in the product, and the first two digits indicate the type of material, as follows: 12 -- chlorinated biphenyla 25-- blend of chlorinated biphenyls and chlorinated tripfaenyls (75:25) 44 --- blend of chlorinated biphenyls and chlorinated triphenyls (60:40) 54-- chlorinated triphenyls For nearly every Arodor mentioned, a darker, less-pure grade exists, with about the same physical and chemical characteristics, but lower in price. _______________________________ The Aroelor liquids and resins are readily soluble in most common organic solvents and drying oils. Although all Arodor plasticizers are insoluble in water, the hard, crystalline materials are generally less soluble than the liquids and softer resins. Solubilities of some Aroelor plasticizers are shown in Table 1. fl i ,1 6.

In general the low-chlorinated biphenyls have the lowest viscosities (Figure 3). Ylxoslty, Saybolt Universal Second* t lI 11 : TOWOLDMON0003469 WATER_PCB-00000491 Torfriti And Sail Handlist hhthifM At ordinary temperatures the Aroclor chlorinated polyphenyls have not presented industrial toxicological problems. Tbc hazard of potential trade exposure varies with their volatility; the lower-chlorinated, morevolatile ones present more of a potential problem from the standpoint of both inhalation and skin contact. When Aroclor plasticizers are used at elevated temperatures, engineering controls must be applied, either by the use of dosed systems or by effective local-exhaust ventilation together with general workroom exhaust. Vapor of the liquid Aroclor plasticizers at room temperature should not be breathed in a confined space, and no vapor of any Aroclor evolved at elevated temperatures should be allowed to be dispersed into the general workroom. Inhalation tests on animals indicate that the maximum safe concen tration of vapor is in the range of from 0.5 to 1.0 milligram of the lower-chlorinated Aroclor plasticisers per cubic meter of air. The threshold limit values (maximum allowable concentration for an 8hour working day) set by the American Conference of Government Hygienists are 1.0 milligram of the lower-chlorinated Aroclor com pounds per cubic meter of air and 0.5 milligram of the mote-highlychlorinated compounds, such as Aroclor .1254, per cubic meter of air. SUatama Schwartz patch tests on 200 volunteers showed that Aroclor 1264 was neither a primary skin Irritant or a sensitizer. Prolonged or repeated skin contact with the Aroclor plasticizers must be avoided by the use of (doves and protective garments, because of the possible occurrence of a condition called chloracne. Although re ports of this condition caused by Aroclor are rare, it can be produced by excessive akin contact. If any Aroclor Is spitted on the skin the skin should be washed in the usual manner with a soap solution. A burn caused by contactwith a hot Aroclor should be treated like any ordinary burn. Aroclor plasticizer adhering to the burned area need not be removed immediately, unless treatment of the bum demands it, in which case either soap and water or repeated washings with a vegetable oil tue recommended. toY/rerniemfffus/ifs Arcelor 1232, Aroclor 124% Aroclor 1248, Aroclor 1254, Arodor 1260, Aroclor 1262, Arodor 1268, Arodor 446% and Montar 1 all contain polychlorinated biphenyls (PCB) of -various types and in varying amounts. FCB residues n small amounts have been found in the environment and some studies have indicated that they may he harmful to certain forms of animal life. Extreme care should therefore be taken by all users of PCB-containing products to prevent any entry into the environment through spills, leakage, use, disposal, vaporization or otherwise. Further, the products in which PCB materials are used, or which are formulated using PCB materials as a component, should be given careful study to diminate the possibility that PCB might reach the environment as a result of use in a given application. Some specific applications where the use of PCB should definitely be avoided are in paints and sealants for swimming pools, paints and waterproofing agents in silos and other buildings where food products for humana or animals are stored, and as a component of any container or wrapping used in the packaging of food products. 13 TOWOLDMON0003471 WATER_PCB-00000493 t K Shipping Freight OUurifieation Arodor 1221,1282,1212, Synthetic Resin, Liquid, NOIBN 1218,1264,1260,1262 Kail Classification Aroclor 1268, 4466, 6442, 6460 Synthetic Resin, Other Than Liquid, NOIBN Truck CUuBtficalion Aroclor 1268 Arodor 4465, 6442,6460 Synthetic Resin, Powder, NOI .
