International Zinc Association Update: Status of Environmental Regulations, Research, and Emerging Issues Eric Van Genderen International Zinc Association AGA Tech Forum 3 October 2012 Salt Lake City, UT
Outline • IZA Overview • Zinc Nutrient Initiative • Regulatory Affairs • Environmental Research • Recycling • Sustainable Development • Communications
IZA Overview IZA’s mission is to support and advance zinc products and markets through research, development, technology transfer and communication of the unique attributes that make zinc sustainable and “essential for life”
Zinc Nutrient Initiative • Global program seeking to: • Improve crop yield • Improve nutritional value of crops • Improve human nutrition • Increase economic returns
Copenhagen Consensus 2008 Eight leading economists, 5 of whom are Nobel Laureates, agree that child malnutrition can best be solved economically with vitamin A and Zinc
Copenhagen Consensus 2012 Eight leading economists agree that the number one solution to the world’s leading challenge is to bundle micronutrients—including zinc Top 5 Investment Strategies: Bundled micronutrient interventions to fight hunger and improve education Expanding the Subsidy for Malaria Combination Treatment Expanded Childhood Immunization Coverage Deworming of Schoolchildren, to improve educational and health outcomes Expanding Tuberculosis Treatment
Zn Deficiency in Soils Is the most commonmicronutrient deficiency Occurs in 50% of the world’s agricultural soils Moderate Zn deficiency Widespread Zn deficiency Directly correlates to zinc deficiency in humans –especially in developing nations that rely on cereal crops Will prevent plants from reaching their full potential even if their macronutrient needs are met Can be corrected with a simple, sustainable solution

Activities of the ZNI Research • In-country crop trials with rice, wheat, corn, etc. Policy Initiatives • Centralized (subsidies and recommendations) • Market-based (farmer Co-Ops, industry Associations) Education and Outreach
Partnership for Child Survival A declaration at the Child Survival Call to Action event June 14-16, 2012 announced a new global partnership to end child pneumonia and diarrheal deaths in high burden countries. The declaration unites the public and private sector as well as NGOs and governments, including IZA.
Mining Compact for Child Health • Companies commit to one or more of the following multi-stakeholder activities: • Support efforts to scale up zinc and ORS treatment. • Increase demand in target countries with advertising and awareness campaigns. • Leverage existing distribution channels to increase access to zinc and ORS, particularly in remote areas. • Support a long-term affordable supply of zinc in the countries with the highest numbers of under 5 child deaths. • Advocate with governments and other stakeholders in the target countries.
Regulatory Affairs US EPA Criteria Update • Currently hardness-based, BLM update submitted in 2006 • Peer-reviewed assessment published in 2012 (IZA participation) • Expanded toxicity database • Unified zinc BLM for acute and chronic toxicity • Acute criterion increases 4-300% • Chronic criterion consistent with EU (no AF!!) • Package of BLM-based updates forecasted (Ag, Cd, Ni, Pb, Zn)??
Regulatory Affairs Stormwater Runoff • West coast USA (CA, OR, WA) pressures • Covenants on exposed metallic surfaces • Dept. of Transportation regulations • Conservative discharge benchmarks • Source reduction guidelines • IZA working with AGA on communication/messaging
Regulatory Affairs REACH • IZA manages several consortia for registration of substances • Zn, Cd, In, Ge?, Ga? REACH-like • China, Canada, Australia, South Korea, Russia, Turkey, USA, California
Transportation IMO convention on marine pollution revised: Stricter regulations on dumping of residues at port Stricter regulations for marine transport of hazardous solid materials in bulk Industry concern on metal concentrates: Do they meet the criteria for being “hazardous” Stricter regulation, higher costs for transport and handling
Transportation Majority of ports have NO treatment facilities Will ports refuse cargo?
A Global Harmonized System? Not Yet!
Environmental Research Generating sound science in support of regulatory, sustainability, and communication activities through research in aquatic, terrestrial and benthic environments
Zinc Runoff Model • Integration of existing models for zinc corrosion (Zinc Coating Life Predictor) and bioavailability/toxicity (BLM) to predict potential changes in freshwater receiving stream environments related to zinc runoff
Rainfall SO2 Temperature Atmosphere Runoff Conceptual Model Roof Area Corrosion Properties Inclination Architecture Catchment Area Soil Properties Receiving Water Characteristics Environment
Response to SC Opinionon Mixtures • Draft opinion on Toxicity and Assessment of Chemical Mixtures (July 2011) • Scientific Committee on Health and Environmental Risks (SCHER) • Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) • Scientific Committee on Consumer Safety (SCCS) • Industry response, through Eurometaux, on metal-specific considerations • Metals have wealth of scientific data • Complex and extraordinary aspects (essentiality, bioavailability, etc.) • Deviation from Concentration Addition • Final Opinion (February 2012) “[this opinion] does not address metals for environmental combination assessment because these assessments require the use of specific approaches, e.g. essentiality, background concentrations, bioavailability.”
Key Messages Metal mixture risk assessments must include: • Variability • Bioavailability • Simplifying complex principles Synergism is not evident!
Comprehensive Tool
Marine Bioavailability DOC and Salinity Interactions • Range of DOC (0-10 mg/L) and salinity (5-30 ppt) • Salinity protection ≥ isosmotic point • DOC protection is not evident in full strength sea water (no normalization) DOC important for risk characterization in transitional waters
IZA Recycling Program Ensure the zinc industry has reliable recycling data and statistics to communicate positive attributes of zinc in a sustainable society • Follow and address relevant policies, initiatives and directives • Establish productive communication among resource management stakeholders • Collect consumption and use data
Zinc production, consumption, and resources zinc extracted throughout history (from ~12th century to present) ~500 million tonnes1 (graph drawn to scale) zinc currently in use 281 million tonnes2 world zinc resources 1.9 billion tonnes world zinc reserves 250 million tonnes1 world zinc consumption in one year 16 million tonnes1,3 mined zinc in worldwide production in one year 12 million tonnes3 zinc recovered/recycled at end of life in one year 4 million tonnes1 1.

Policies Including Recycling • Life Cycle Assessments • Raw Materials Initiative • Waste from Electronics • Construction Works • Eco-labeling • Green Public Procurement • Eco-design • Waste Directives

Support of Steel LCA Report • The Steel Framing Alliance (SFA), with support from IZA, released a critical review of an LCA comparing wood and galvanized steel building materials. • The LCA conducted by wood industry was found to be incorrect in several areas: • Over-estimating the amount of steel in the building by 32%, an error that increased the claims of CO2 emissions. • Using 10-year old data that has since been revised which exaggerated both CO2emissions and energy consumption. • SFA is considering next steps with report
Communication • Technical brochures • Publication of articles/book • Fact sheets • Newsletters • website: zinc.org • Videos • Seminars/workshops • Training programs
