International activity of chemical management

History

• Agenda 21 : adopted in1992 at World summit
• Inter-governmental Forum On Chemical Safety

: Set up in 1994

• Strategic Approach to International Chemicals

Management (SAICM) : adopted in 2006 at Dubai.

International activity of chemical management

SAICM 国際的化学物質管理戦略 Sub-title : Comprising the Dubai Declaration on International Chemicals

Management, the Overarching Policy Strategy and the Global Plan of Action.

Objectives: Risk reduction Knowledge and information Governance Capacity-building and technical cooperation Illegal international traffic

SAICM Chemical Risk reduction By the year 2020, chemicals are produced and used in ways that minimize significant adverse impacts

• n the environment and human health

International activity of chemical management

5

SAICM is progressing for the risk reduction by 2020

• Pesticides：

Regulatory systems have been introduced or strengthened

• High Concern substances：

POPS/Heavy metals/CMR substances：Mostly prohibition

• Existing chemicals：

EU : implemented REACH in 2007.

Registration, Evaluation, Authorisation and Restriction of Chemicals

Japan: Plan to revise the chemical control law to review the life-cycle of all existing chemicals.

Conclusion

It is going toward throughout control of entire life cycle including products and articles containing chemicals. How about ships? IMO responds

• On ship recycling to minimize the hazardous waste
• Chemical use for Ballast tank (G8）
• Antifouling system (AFS treaty)

IMO Resolutions with AFS Convention

• Resolution 2:

The Conference invites States to approve, register or license anti-fouling systems applied in their territories, bearing in mind the information contained in Annex 3 of the Convention.

• Resolution 3:

The Conference urges States to continue the work, in appropriate international forum, for the harmonization of test methods, assessment methodologies, and performance standards for anti-fouling systems containing biocides.

Why ISO standard?

Marine has no borders. The assessment should be harmonized. To respond to AFS treaty in Resolution 2 & 3, need a harmonized tool to judge acceptable AF systems. ISO is an appropriate forum to discuss such a global issue.

Bioaccumulation Sediment Settling and Partitioning Biological Degradation Deposition Volatilization Aerosol Leaching UV Degradation Hydrolysis Speciation Biological Degradation Burial Sorption to particlate matter Hydrodynamic transport

• tide, currents
• density (S)
• river flux

The risk assessment covers the service life after leaching active substances.

Scope of Risk Assesment

Environmental Risk assessment

Leaching rate ↓ Exposure scenario For service life ↓ PEC calculation Safety & E-fate studies ↓ Hazard characterization ↓ Decides UF ↓ PNEC calculation

PEC/PNEC Judgments & Decision Persistency, Bioaccumulation paint AIs

Tier1

(+ 3 acutes & 1chronic, Degradation, fish accumulation)

Low bioaccumulation (BCF<100) Readily degradation（HL<15days) PEC/PNEC<1

Tier 2

BCF<100 & HL<60days Or BCF<1000 & HL<15days

Level 1

(+2 chronics+ Sediment accumulation) PEC/PNEC<1

Overall low risk

• ISO TC8/SC2

NWIP

• Due to harmonize the risk

assessment and the safety studies, hope that each of countries will join the WG of ISO TC8/SC2. End.
