UNEP POPs GEF Project - Workshop on Persistent Organic Pesticides, Geneva, February 22-26, 1999

OECD Project on POPs

Risk assessment associated with long term low dose exposure to persistent, bioaccumulative and toxic pesticides

Suzanne Fortin

APPENDIX 5


Overview of presentation

• Link to UNEP GEF project

• Persistent organic pesticides

• Why propose the project?

• Goals and overview of OECD project

• Summary closing


Link to UNEP GEF project

• Substances targeted– POPs include PBT pesticides– same fundamental characteristics

• POP threat, for the future


Persistent organic pesticides

• POPs already identified – e.g. UNEP, UNECE

• POPs may exist among pesticides already in use

• POPs may occur among new pesticides that are proposed for use


Why propose the project?

• Increased focus on POPs/PBTs (TSMP)

• Questions about RA of PBT substances– especially borderline substances

• International commitments related to new POPs/PBTs

• Other countries may have similar questions

• Harmonization of elements of the RA


Goals of the OECD project

• Clarify information available and how it is used

• Guidance/consistent approach to assist in preventing the continued development and use of new POP/PBT pesticides

• Identify new data requirements and need for developing test guidelines


Parameters

• Build on relevant activities– selecting POPs; predicting LRT potential; using

models and monitoring in RA

• Focus on ecotoxicity and environmental fate


Outcome

• Knowledge of available information

• New data requirements (UNEP? SETAC?)

• New test guidelines

• Harmonization of approaches (throughout and next steps)


Stages

• Questionnaire to collect RA info

• Exercise

• Monitor related activities (ongoing)

• Review information and draw conclusions


Questionnaire focus

• Information available/data required

• Test guidelines followed

• Monitoring data and models, what and how

• Data interpretation

• RA principles/policies


Specific results anticipated

• Id. areas of agreement

• Id. important differences

• Harmonization (current and subsequent)

• Consistency with related activities

• Id. new data requirements and necessary test guidelines


Summary closing

• Relationship to GEF - substances/threat

• Focus is on long-term low-dose exposure to new POP/PBT pesticides

• Improve RA capacity with a consistent international approach/harmonization.

• Prevent the release of new POP/PBT pesticides and related threats.
