UK National Implementation Plan for the Stockholm Convention on Persistent Organic Pollutants

The UK National Implementation Plan (NIP) for the Stockholm Convention addresses persistent organic pollutants (POPs) and outlines regulatory controls, emissions trends, and actions taken since its ratification in 2005. The second NIP, published in 2013, focuses on reducing emissions from 10 POPs and one unintentional by-product while highlighting challenges such as limited data on new POPs and controlling diffuse sources of emissions. This plan is critical for improving environmental quality and public health by managing hazardous substances and their impacts.

  1. UK National Implementation Plan (NIP) for the Stockholm Convention on Persistent Organic Pollutants (POPs) – Current issuesJaya Shah April 2013

  2. Obligations of the Stockholm Convention • 2005 - UK ratified • 2007- 1st National Implementation Plan • 12 POPs, 4 unintentional by-products • http://archive.defra.gov.uk/environment/quality/chemicals/documents/pop-nationalplan.pdf • 2013 - 2nd National Implementation Plan • 10 POPs, 1 unintentional by-products • https://www.gov.uk/government/consultations/update-to-the-uk-national-implementation-plan-2007-for-the-stockholm-convention-on-persistent-organic-pollutants • https://www.gov.uk/government/publications/persistent-organic-pollutants-national-implementation-plan

  3. Overview of the plan • Situation in the UK • Use, production and legacy issues • Regulatory controls • Emissions and trends • National Action

  4. Listed Pesticides - Regulatory controls

  5. Industrial chemicals – regulatory controls

  6. Unintentionally produced • Dioxins and Furans • by-products of combustion processes, industrial processes regulated • Hexachlorobenzene • contaminant level in chlorothalonil controlled • Pentachlorobenzene • quintozene not approved since 2002

  7. Emissions data - sources • NAEI - National Atmospheric Emissions Inventory, since 1990, activity estimates and emission factors • IPPC/EPR Pollution Inventories – EU Integrated Pollution Prevention and Control Directive/Environmental Permitting Regulations Pollution Inventories, since 1995 • UK PRTR – United Kingdom Pollutant Release and Transfer Register, since 2007

  8. Challenges – 2007 NIP • Dioxin Action Plan – Dioxin Strategy Group • evaluation of current and projected release inventories for dioxins, PCB and HCB • develop and maintain source inventories and release estimates – • reducing emissions of unintentionally produced POPs • Emissions inventory – only air vector in 2007

  9. 2010 - What do the releases tell us?

  10. Annual releases of dioxins, PCB, HCB and PeCB in 2010

  11. Dioxin emission trends – Air, Land and Water

  12. PCB emission trends – Air, Land and Water

  13. Challenges – 2013 NIP • Very limited available data for new POPs • Diffuse sources of unintentionally produced POPs – improved understanding of emission sources and factors, difficult to control • Emissions from products in use and entering the waste stream – managing emissions

  14. What are we doing next? • Listed POPs – uncontrolled emissions • PBDEs in non-electronic consumer products • Listed POPs - potential legacy sources • Lindane, alpha and beta hexachlorocyclohexane • Emerging candidates • Food and Standards Agency activities

  15. Candidate POPs – WORK IN PROGRESS • Dicofol • Hexabromocyclododecane (HBCD) • Hexachlorobutadiene (HCBD) – No use or production in EU, unintentional by-product (Annex D) • Pentachlorophenol (PCP) – No use and production in EU • Chlorinated naphthalenes (PCNs?) – No use and production in EU, unintentional by-product • Short chained chlorinated paraffins (SCCP) – restricted in EU since 2002
