Reducing Human and Environmental Risks from the Insecticide Lindane Irina Ize and Keith Chanon ACS symposium SMOC WG Meeting March, 2005
Outline • Background • Status of Lindane in North America • Canada • US • Mexico • NARAP development process and highlights • Next steps
Why a NARAP on Lindane and Other HCH Isomers? • Persistent, toxic, and bioccumulative organochlorine pesticide • Continues to be used for varying applications in the 3 countries • One of the most abundant and pervasive organochlorine contaminants found in the environment • Nominated as a substance of regional concern by the U.S. in 1999
Chemical Structure Gamma - HCH
Status of Lindane in North America Lindane is currently used in the agriculture, veterinary and pharmaceutical sectors. • Seed treatment • Protect livestock from ticks, fleas and other insects • Use on ornamental plants • Used in shampoos and creams to treat head lice and scabies
US and Canada joint reevaluation Canada and U.S. collaborated to reevaluate the registered agricultural uses of lindane (1999-2002)

NARAP Development Process • Establishment of the Lindane Task Force (2003) with membership from government and a wide range of public stakeholders from all three countries • Pesticide industry, academia/children’s health, environmental groups, indigenous groups • Indigenous representation from all 3 countries • Alternates from different countries
Stakeholder Outreach • Two public meetings – Guadalajara, Mexico (2003), Anchorage, Alaska (2004) • Countries initiated separate national outreach efforts to determine domestic regulatory actions
Stakeholder Outreach in Mexico – an Example In anticipation of the NARAP, the National Institute of Ecology (INE) published a “National Diagnostic Report” • Updates statistics on production, imports, exports • Identifies commercial names, prices, selling patterns, quantities used… • Identifies possible alternatives and economic implications
Stakeholder Outreach in Mexico – an Example • Groundbreaking process led by (INE) and the Ministry of Environment to develop a regulatory position on lindane • 3 stakeholder meetings with participation from industry, academia, indigenous and environmental groups • information sharing between the different sectors • analysis of alternatives • discussion of phase-out and use reduction options
National Actions Resulting from the Task Force and Outreach Activities • Mexico – commitment to phase-out all lindane uses • U.S.–re-evaluation of the seed treatment uses to determine if they meet current safety standards; work with pharmaceutical companies to facilitate development of alternatives • Canada – will monitor the pharmaceutical use of lindane and explore measures for addressing potential health and environmental risks
Key Issues Identified by the Task Force • Production – waste isomers • Wastewater • Import/export • Alternatives • Subsistence diets • Long range transport
Lindane NARAP Goals and Objectives Cooperativelytake actions in the three countries towards reduction of exposure of humans and the environment to lindane and other HCH isomers • Reducing or eliminating uses • Providing and promoting outreach and education in North America • Encouraging science and research and the use of safer alternatives • Engaging in capacity building through the development of strong and effective partnerships, and • strengthening working relationships between regulatory agencies in the three countries
Lindane NARAP Actions • Pharmaceutical • Agriculture – Veterinary • Agriculture - Pesticide • Trade Issues • Waste Management Issues • Science and Research • Outreach and Education • Ensuring Compliance • Leveraging Resources • Integration with International Activities
Lindane NARAP Highlights • Workshop on alternatives, organic methods and integrated strategies • Inventory of lindane products • Outreach and education efforts to inform of possible risks associated with lindane and alternatives • Support a biomonitoring survey
NARAP Highlights (cont.) • Promote research and exchange information on • exposures resulting from lindane uses • the environmental effects associated with the use of lindane • Share information on national enforcement strategies and commit to enforcing actions through existing legal frameworks
NARAP Highlights (cont.) • Address environmental contamination caused by the production of lindane and HCH isomers • For every ton of lindane produced, between 5-6 tons of unwanted waste isomers are generated • Work through international organizations and support risk reduction activities in China and India
Next Steps • Complete government interagency review • SMOC review • 30 day public review • Complete final government interagency review • Final task force review • Final SMOC review • Council approval (November 2005) • Establish an implementation task force
Conclusions • Regional cooperation is a powerful means for reducing and eliminating risks • Risks from long-range transport require regional and international collaboration • NARAP process and the CEC strengthens regional action ensuring public participation • Health and environmental risks will be reduced significantly as the NARAP is implemented
