PCB’s in Small Capacitors from Waste Electrical and Electronic EquipmentsWe may assume that the situation in Switzerland doesnot differ much from that in Austria. By converting thetotal annual fl ow 2006 in Austria proportionally to theSwiss population fi gure, we reach a PCB fl ow of approx.8’500 kg/a from WEEE in Switzerland. Compared withSwiss consumption fi gures, circumstances abroad andformer examinations, and in spite of the analyticaluncertainties, the fl ows derived from the analyses areplausible.4.3 PCB SubstitutesAll matters and groups of substances identifi ed qualitativelywith the screening methods described under paragraph3.3, are presented in Table 10. In most of thecases, larger groups of substances with a great numberof individual matters are found, and these latter can varyconsiderably from each other. Interpretations must thereforebe made with great reservations. As far as it isknown, the substances are subdivided according totheir functions in capacitors and labelled with the EUClassifi cation Risk Phrases for Hazardous Substances.As a fi rst priority, the offi c ial classifi cation of hazardousmatters was founded upon the Directive (1967/548/EWG). A list of the hazardous matters with their respectiveclassifi cation is given in Annex II of the present Directive.Hazard classifi cations for substances not includedin this list can be found in safety data sheets frommanufacturers or other databases, such as the IUCLID 9Chemical Data Sheet.Table 10: Overview of identifi ed substance groups following capacitor samples with the marking ofhazardous materialsIdentified Substances andSubstance GroupsMarking of Hazardous MaterialsOfficialAnnex II 67/548/CEElectrolytes, Solvents and Other AdditivesOther SourcesN,N, dimethylacetamide, R20/21, 36, 40, 61 X X(2-)hydroxybenzoic acid R22, 37/38, 41 XBenzyl alcohol R20, 22 XDimethylbenzyl alcohol R22, 36/37/38 XPCB Substitutes (Dielectrics)Naphthalene R22, 40, 50/53 X X X X XChlorinated naphtaleneR20/21/22,36/37/38X X X X XDibutyl phtalates R40, 50, 61, 62 X X X X X X X XDiethyl phtalates X X X X X X X XDiethylhexyl phathalates R40, 60, 61 X X X X X X X X1,1-diphenyl ethan2,2’-dimethyl biphenylBiphenyl, substituted(alkyled) biphenylsXXX X 10 X XDiverse hydrocarbons X X X X XMatters with Unknown Function(1-)methyl naphthalene R22, 36/37/38,42/43, 51/53Triphenyl phosphate R50/53 XHexabrom-benzene1,11-dibromoundecaneR20/21/22/22,36/37/381 LHA MIxture2 Dishwashers3 SHA MixtureX4 MicrowavesX5 Cooling and freezingappliances6 Fluorescent Tube Lamps7 IT / CE < 1 cmX8 IT / CE 1 – 2.5 cmX7 IT / CE > 2.5 cm10 UPS Systems9International Uniform Chemical Information Database10Quantitative value: 18 % referring to capacitor weight16
