Polychlorinated biphenyl3 (PCBs) are a group of stable substances comprising theoretically more than 200 individual compounds, many of which are widely used particularly because of their dielectric properties and non-flammability. At present they are obtained through chlorination of diphenyl, resulting in mixtures that arc characterised by their average content of chlorine. Due to the persistence and toxicity of some of these compounds(1), effects have been observed in the environment and accidents reported over the last few years, which have given rise to serious concern in Member countries. In view of this concern, the Sector Group on Unintended Occurrence of Chemicals in the Enviromont has investigated, on a priority basis, the need for, and feasibility of, conoerter action to control the use and emissions of PCBs. The results of this enquiry, which have been presented in document NR/EKV/72.49, lead to the following con clusions: (a) Because of unacceptable levels of PCBs found in the environment und because of a number of incidents involving human health, some countries have taken, or are considering taking action to control the use of PCBs: (b) There are (1972) only six companies in O.E.C.D. Member countries that manufacture PCBs; five of them have already taken steps to reduce production to the supply for a few approved uses; (c) PCBs can be replaced except for some users whore their dielectric properties and non-flammability are essential; (d) The technology for destruction of PCBs exists; (e) Because of the many applications of PCBs in the wide range of consumer products moving j.n international trade, the situation will almost certainly become complicated unless international agreement is reached on allowable uses; (1) As uf the time of the preparation of this Note, limited research studies with certain selected PCP-compounds seem to indicate that some of these compounds could eventually safely be used for certain applications. MONS 040X25 -5- C(73)l(Final) Appendix (f) A rough estimated) indicates that consumption of PCBs in O.E.C.D. countries is matched by production. Considering in addition that import of chemicals fx-om uon-O.E.C.D. to O.E.C.D. countries is still re stricted to basic chemicals, import of bulk PCIis is unlikely. It is, therefore, reasonable to suggest that the major part of the problem of unintended occurrence of PCBs can be solved through concerted action between O.E.C.D. Member countries. USES OF PCBs 2. The applications of PCBs fall mainly into two categories: - uses in closed systems; - dissipative uses. CLOSED SYSTEMS 3. The use of PCBs in closed systems can be defined as applications from which the PCBs are recoverable. PCBs in transformers, capacitors, heat transfer systems, hydraulic equip ment, and vacuum pumps are in principle recoverable, since during use, the PCBs are not generally dispersed into the environment. 4. It is, however, important to distinguish between closed Bystem uses that are controllable in practice and those where control cannot be guaranteed either: - because frequent replacement of relatively small quantities will lead to disposal rather than recovery, or - because a large number of small units widely dispersed will make collection extremely difficult, or - . because accidental leakage will cause imminent danger to human health. 5. A truly controllable use may therefore be defined as an application where: - the PCBs arc contained in a sealed circuit in large, long-life units; - the quantities involved ore such that there is an incentive for regeneration. (1) Production in 1971 amounted to about 48,400 metric tons and consumption in the 13 countries that provided numerical information to about 33,300 tons. MONS 040126 Cl73;i lFinal; Appendix 6. Following what has been said above, the only truly controllable uses of PCBs are in dielectrics for transformers and for larac capacitors for power factor correction, fret venting escape of PCBs from these applications is mainly a problem of engineering design and of collec tion and rtmlructinn of used liquids, or, in the case of capacitors, of removal and destruction of PCB-impregnated material. These uses also being essential for safety reasons, it would be unreasonable to suggest that they be discontinued at the present time. 7. In all other closed systems, recovery of PCBs, although theoretically possible, would not be practical. Such applica tions should, therefore, be discontinued, unless safety require ments prevent the use of substitute products: (i) Heat transfer systems There may be some installations where the risk of explosion or fire must be avoided at all cost, and the danger of some escape of PCBs therefore is of less importance. Because of the risk of leakage, which can never be totally guarded against, the use of PCBs as heat transfer media in the food, drugs and feed industries should, however, be prohibited. (ii) Hydraulic equipment, vacuum pumps Although the quantities involved in the individual case are relatively small, they will, unless recovered, add significantly to the environmental burden of PCBs. Theoretically, used fluids could be recovered, but in view of the difficulty of establishing a system to collect small quantities from many users, these applications should be dis continued. Furthermore, PCBs are generally not essential in hydraulic and pumping fluids, with the possible exception of hydraulic equipment in under ground mining. (iii) Small capacitors These are typical examples of an application of PCBs in sealed units that are almost completely nonrcoovcrable. Considering, for example, the many domestic doctrinal appliances in which capacitors are used, the coot of recovery would probably be prohibitive. A warning label showing that the equipment must not be disposed of as ordinary wantchao been suggested; it is however, not likely to bo sufficient, unless manufacturers and retailers HONS 040127 -7- C(75)1(Final) ' Appendix would accept return of appliances that arc out of use. The problem of recovery remains unresolved at the present time, but it has to be noted that Japan has stopped the use of PCJis in the manufacture of small capacitors. DISSIPATIVE USES 6. The dissipative uses are those where recovery of used PCB8 is not possible, since they are not contained in closed systems but in direct contact with the environment: (i) lubricating and cutting oils The conditions under which these oils are used are such that there is continuous emission of small quantities into the environment. These applications, not being essential, should be discontinued; (ii) Pesticide Use This use has fortunately been abandoned in most countries already; if not, it should bo banned with immediate effect. Since all O.E.C. D. countries require registration of pesticides, such a measure can easily be taken under existing legislation; (iii) Plasticisers ' The most important category, by volume of dis sipative use is in the field of plasticisers. They are or have been used in most countries in a wide variety of consumer products including paints, inks, copying paper, adhesives, sealants, plastic products, etc., many of which are traded internationally. The major applications seem to be in the printing and paint industries. 9. The Printing Industry: Because of the risk of contamina tion of paper .""which after "recycling may be used in food packaging, the use of PCDs in the printing industry should be banned. In view of the fact that printing inks can be produced without PClis and that in any case l.lio amount used probably represents a total value of only about *5-),000 in 0.J3.C.D. countries, such a measure should not cause serious economic damage. Assuming that copying paper is usually provided by the copying machine manu facturers (relatively few and big companies), any economic effects should be small. 10, Jhe_JVitn_t Jjartustry poses a somewhat different problem. Over the'Tast decade, production has increased by 3.5 per cent 5 per cent annually and the trend is rising in the O.E.C.D. area. HONS 04QW8 C(73)l(Final Appendix -8 The over 2,000 million dollar West European paint industry alone accounts for some 40 per cent of the world output. Production is assured by a few large and a great many small companies (United Kingdom = 480, Italy and France = 350 etc.). This picture suggests that an overall ban on PCBs in paints could have some economic consequences. It appears, however, that where uoed (e.g, in stoving applications) PCB3 constitute something like 5-10 per cent of the paint. Few details are available in respect of the amounts used in paints, but taking one example (France) where 250 cons were used (1971) in a paint industry that produced something like 700,000 tons of paint, presumably only 2500-5000 tons would contain PCBs. Considering in addition chat small paint manufac turers are generally highly specialised, and that the manufac turing process would not have to undergo a major change to re place the use of PCBn , a ban on PCBs should not cause ary serious disturbance. The use of PCBs in paints has, in fact, been discontinued in some countries already. Figures for production (8.654.200 tons in 1969) and consumption (8.517,500 tons) in O.E.C.D. countries again suggest that imnort of paints from ronO.E.C.D. producers may be of minor significance. 11. In practice, none 'v' the products where PCBs have been used as plasticizers can be recovered. Unless the use is totally eliminated, there will be contiguous emissions into the environ ment due to evaporation, insufficient incinceration etc. Judging by the action already taken in several countries, sub stitutes can readily he found for the whole category of plasti cizer use of PCBs, which should, therefore, be banned. 12. It follows from what has been sale, above that for adequate protection of health and environment, but also to avor'.n undue competition in international trade, agreement is necessary on allowed uses of PCBs. In order to ensure that homo production is not substituted by import, control action by governments, through licencing or other means, is essential. Measures are further necessary to ensure collection of used material, safety in transport of raw PCBs, and assessment of substitute materials: (a) A uniform labelling system, internationally recognisable, should be developed for use on containers of raw I'Ciis as well ho on any equip ment or product, containing PCBs. (b) Suppliers (,i.e. manufacturers and importers) should further provide containers for the trans port of PCB-containing liquids: ouch containers must meet the appropriate specifications that have been laid down to ensure safety in transport of dangerous chemicals. MONS 040129 -9- C(73)l(Final) Appendix (c) Development of substitutes that are less hazardous than persistent PCBs(l) should be encouraged, but in v;.ew of the fact that no system for pre-market control of new chemicals has been introduced, testing for environmental effects is so far entirely the responsibility of the manufacturers. Informa tion on replacement products should, therefore, be collected and reviewed. . I (l) See footnote on page <t. HONS 040130
