    1. U g i l e c Re-assessment under provisions of UN-ECE POPs protocol 1st meeting of TFPOP, The Hague March 2004

    2. Ugilec 141 formula C14 H10 Cl4 water solubility 5 ľg/l (20 °C) vapour pressure < 10 Pa (20°C) log Kow 6.03 – 6.44 log BCF 1.67 – 2.68 l/kg (fish) 4.43 – 5.19 l/kg (mussels) DT50atmosphere (AOPWIN) 3.1 days

    3. Ugilec 121 or 21 formula C14 H2 Cl2 water solubility < 1 ľg/L (20 °C) vapour pressure 0.005 Pa (20°C) log Kow 5.85 (QSAR) log BCF 1.67 – 2.68 l/kg (fish) 4.43 – 5.19 l/kg (mussels) T/2atmosphere (AOPWIN) 2.3 days Data are scarce, Data are difficult to measure due to varying congenere composition and low water solubilityData are scarce, Data are difficult to measure due to varying congenere composition and low water solubility

    4. Annex II of UN-ECE protocol on POPs substances scheduled for restrictions on use

    5. Regulatory Action within the EU Directive 76/769/EEC on the approximation of the laws, regulations and adminisrative provisions of the MSs relating to restrictions on themarketing and use of certain dangerous substances and preparations 11th amendment: Council Directive 91/339/EEC Though less dangerous to man and the environment than the PCBs it was designated to replace … By virtue of its ecotoxcity, persistence and potential to bio-accumulate Ugilec 141 constitutes a high risk to the environment Significant environmental contamination has already been documented in the vicinity of mining operations using this substance as a hydraulic fluid Council Directive 76/769/EEC of 27 July 1976 on the approximation of the laws, regulations and administrative provisions of the Member States relating to restrictions on the marketing and use of certain dangerous substances and preparations [Official Journal L 262, 27.09.1976]. Amended by: a) with reference to Annex I (list of substances and preparations and the relevant measures): i.a. Council Directive 91/339/EEC of 18 June 1991 [Official Journal L 186, 12.07.1991] Whereas several substitutes have been developed to replace PCBs; whereas some of these substitutes, though less dangerous to man and the environment than PCBs and PCTs, nevertheless constitute a potentially high risk to man and the environment Ugilec 141: Whereas by virtue of its ecotoxcity, persistence and potential to bioaccumulate, this substance nevertheless constitutes a high risk to the environment; whereas significant environmental contamination has already been documented in the vicinity of mining operations using this substance as a hydraulic fluid; whereas in the event of a fire involving any equipment containing this substance highly toxic substances may be given off; whereas final disposal of Ugilec 141 requires special procedures Council Directive 76/769/EEC of 27 July 1976 on the approximation of the laws, regulations and administrative provisions of the Member States relating to restrictions on the marketing and use of certain dangerous substances and preparations [Official Journal L 262, 27.09.1976]. Amended by: a) with reference to Annex I (list of substances and preparations and the relevant measures): i.a. Council Directive 91/339/EEC of 18 June 1991 [Official Journal L 186, 12.07.1991] Whereas several substitutes have been developed to replace PCBs; whereas some of these substitutes, though less dangerous to man and the environment than PCBs and PCTs, nevertheless constitute a potentially high risk to man and the environment Ugilec 141: Whereas by virtue of its ecotoxcity, persistence and potential to bioaccumulate, this substance nevertheless constitutes a high risk to the environment; whereas significant environmental contamination has already been documented in the vicinity of mining operations using this substance as a hydraulic fluid; whereas in the event of a fire involving any equipment containing this substance highly toxic substances may be given off; whereas final disposal of Ugilec 141 requires special procedures

    6. Monitoring (Ugilec 141 in German river sediments) concentrations of Ugilec and PCBs in sediments of river Saar (Germany) peaks indicate vicinity of mining operations- using Ugilec 141 as a hydraulic fluid

    7. Regulatory Action within the EC Council Directive 91/339/EEC – (continued) In the event of a fire involving any equipment containing this substance highly toxic substances may be given off Council Directive 76/769/EEC of 27 July 1976 on the approximation of the laws, regulations and administrative provisions of the Member States relating to restrictions on the marketing and use of certain dangerous substances and preparations [Official Journal L 262, 27.09.1976]. Amended by: a) with reference to Annex I (list of substances and preparations and the relevant measures): i.a. Council Directive 91/339/EEC of 18 June 1991 [Official Journal L 186, 12.07.1991] Whereas several substitutes have been developed to replace PCBs; whereas some of these substitutes, though less dangerous to man and the environment than PCBs and PCTs, nevertheless constitute a potentially high risk to man and the environment Ugilec 141: Whereas by virtue of its ecotoxcity, persistence and potential to bioaccumulate, this substance nevertheless constitutes a high risk to the environment; whereas significant environmental contamination has already been documented in the vicinity of mining operations using this substance as a hydraulic fluid; whereas in the event of a fire involving any equipment containing this substance highly toxic substances may be given off; whereas final disposal of Ugilec 141 requires special procedures Council Directive 76/769/EEC of 27 July 1976 on the approximation of the laws, regulations and administrative provisions of the Member States relating to restrictions on the marketing and use of certain dangerous substances and preparations [Official Journal L 262, 27.09.1976].

    8. Regulatory Action within the EC As from 18 June 1994 the marketing and use of Ugilec 141 and of preparations and products containing this substance shall be prohibited. Exception in the case (of the maintenance) of plant and machinery already in service on 18 June 1994 until such plant and machinery is disposed of As from 18 June 1994 the placing on the secondhand market of this substance, preparations containing this substance and plant/machinery containing this substance, shall be prohibited. The marketing and use of Ugilec 121 or Ugilec 21 and of preparations and products containing it shall be prohibited.

    9. Regulatory Action within the EC (waste disposal) Council Directive 96/59/EC on disposal of PCBs and PCTs (and Ugilec) obliges Member States to: Compile inventories of equipment containing more than 0.005% PCBs and mixtures of PCBs, whose volume is in excess of 5 liters Prohibit separation of PCBs for purpose of re-use Prohibit the topping up of transformers with PCBs Safely remove PCBs from transformers containing more than 0.005 % PCBs (or mixtures with PCBs) by weight Allow continued use of PCBs containing transformers only if they are in good working order Destroy waste containing PCBs and equipment containing PCBs as soon as possible (not later than by 2010) Develop installations for the disposal, decontamination and safe (permanent) storage of PCBs

    10. Regulatory Action within the US and Canada U.S. Not on Toxic Substances Control Act (TSCA) Section 8b Inventory of existing industrial chemicals in commerce. Any intended industrial chemical-type use would require 90-day advance pre-manufacture notification (PMN). No other information found suggesting current or historical domestic production Canada Not on the list of existing substances. Intended uses would be treated as new substance, thus being subject to risk assessment and subsequent risk management measures

    11. Outcome from a questionnaire in 2001 At no time commercially available in the US / Canada Manufacture and use ceased in Europe from mid 1994 onwards (“unknown“ for Armenia and Khazakhstan) Lacking information about extent of historical uses (and possibly ongoing uses) phasing-out programme in place along with PCBs (EU) subject to specific waste management system (EU)

    12. Socio-economic considerations - Alternatives Liquid alternatives Mineral oils, silicon oils, castor oil etc. Dry insulating insulating inert gases, resin castings , plastics coatings

    13. related compounds ... Bis(p-chlorophenyl) methane (101-76-8) intermediate for the synthesis of industrial polymers

    14. related compounds ... DBBT (dibromo- diphenyl methane (99688-47-8) regulated in the EU along with Ugilec 121 or 21
