Implementation of Risk Reduction Strategies for PBDEs

  1. 1. Implementation of Risk Reduction Strategies PBDE Team Chemicals Management Forum San Antonio, Texas May 15-16, 2012Commission for Environmental Cooperation
  2. 2. Background and Mandate• The CEC SMOC Working Group established a tri-national polybrominated diphenyl ethers (PBDEs) team to identify opportunities for collaboration in managing this group of substances in North America with the objective to reduce environmental and health risks. 2
  3. 3. PBDE Team Objectives• To develop a strategy that identifies potential risk reduction activities and recommend a work plan to implement them.• To share information on PBDE potential hazards, and routes and magnitude of exposures.• To identify activities that will reduce the risks presented by PBDEs.• To increase interest, engagement and participation of stakeholders in PBDE risk-reduction activities. 3
  4. 4. Group members• Each country designated representatives and one alternate to be on the PBDE team.• The members work collaboratively to carry out the activities of the working plan. 4
  5. 5. Activities timeline Development of a PBDE content in Characterization of Characterization of PBDE and BFR PBDE Matrix of PBDE content in in landfill leacheates and biosolids plastics and Current Status end-of-life products of North America polymers of In the three in two typical countries (US, electronic landfills in Mexico Identification of PBDE and BFR CAN, MEX) products used in SMEs in Mexico 2006 2007 2008 2009 2010 2011 2012 PBDE Information PBDE PBDE content in Analysis of Identification working exchange among children’s blood from available and the three diagnosis four metropolitan techniques and group priorization of countries (US, in Mexico areas of Mexico environmental PBDE andcreation in CAN, MEX) (El Refugio, SLP; San practices for the the CEC BFR Juan Tilapa, Edo management in alternatives MEX; Ciudad Juárez, recycling and waste CHIH; Tlachaloya, management in Mexico Edo MEX streams 5
  6. 6. Relevant activities 6
  7. 7. 2009• PBDE Mexican Inventory – Development of the diagnosis of consumption, use, disposal and release of PBDEs in Mexican market and environment, particularly for the commercial mixtures of Penta, Octa and Deca BDEs, either in its pure form or contained in imported, exported and manufactured products and formulations. 7
  8. 8. 2010• PBDEs flow in landfills – Identify the PBDEs containing materials that are included in the wastes taken at two typical landfills in Mexico (Tlalnepantla and Bordo Poniente).• PBDEs in blood – Analyze the concentration of PBDEs in blood of children from exposed populations in three locations of Mexico. – Sampling in the communities of Milpillas, El Refugio (S.L.P.); Ciudad Juarez (Chihuahua); San Juan Tilapa, Tlachaloya (Estado de México). – Propose potential routes of exposure to PBDEs to support the development of needs assessment. Ciudad Juárez, Chihuahua El Refugio, Cd. Fernández, San Luis Potosí San Juan Tilapa, Estado de México Tlachaloya, Estado de México 8
  9. 9. 2011• Identification of BFRs used in SME’s in Mexico – Identify the contribution of BFR´s used in SME´s in Mexico and the action lines to risk reduction strategies. – Describe the environmental and socio-economic implication for the use of BFRs and alternatives to them.• BFRs in landfill leachate and biosolids in North America – Identify the contribution of brominated flame retardants in landfills and biosolids from Mexican landfills as well as capacity building for analysis. – Field visits to two landfills in Mexico to sample leachates and biosolids for subsequent analysis. – Technical training of Mexican researchers for preparation, extraction of samples and analysis samples.• Available techniques and environmental practices for the management of waste streams with BFRs – Identify known approaches to the management in recycling and waste management streams of plastic products containing brominated flame retardants, including, incineration, land-fill management, and recycling and/or separation. 9
  10. 10. Next steps (2012)• Identification and prioritization of alternatives to PBDEs/ BFRs, with characterization of risks and costs in specific applications in Mexico• Second phase of the characterization of PBDEs/BFRs in landfill leachate and biosolids. Focus on capacity building for analysis in Mexico. 10
  11. 11. Path forward• Knowledge increased on presence and releases of PBDEs in North America.• Continue assessment on PBDEs/other BFR releases to environment.• Trinateral cooperation to identify approaches for risk reduction in North America.• Knowledge increased on alternatives. 11
  12. 12. Transparency and public access to information• Developing a fact sheet with information on BFRs used in Mexico. 12
  13. 13. More information available• Commission for Environmental Cooperation –• US Environmental Protection Agency –• Environment Canada –• Instituto Nacional de Ecología – 13
