  1. Pellet Watch : Global Monitoring of Persistent Organic Pollutants (POPs) using Beached Plastic Resin Pellets Hideshige TAKADA, Yukie MATA, Satoshi ENDO Laboratory of Organic Geochemistry Tokyo University of Agriculture and Technology, JAPAN E-mail : shige@cc.tuat.ac.jp Rei YAMASHITA (Hokkaido University, JAPAN) (Universiti Putra Malaysia,, MALAYSIA) Mohamad Pauzi ZAKARIA

  2. Self-Introduction : Hideshige TAKADA, Ph.D Laboratory of Organic Geochemistry (LOG), Tokyo University of Agriculture and Technology

  3. Plastic Resin Pellets as a Transport Medium for Toxic Chemicals in the Marine Environment Environmental Science & Technology 2001, vol.35, 318-324

  4. Topics • Introduction of marine plastic resin pellets. • Types of contaminants detected in marine plastic pellets. • Adsorption of contaminants to plastic pellets. • Relationship betweencontaminant concentrations in beached resin pellets and levels of marine pollution. • Proposal of Pellet Watch : Monitoring of POPs using beached plastic resin pellets.

  5. Plastic Resin Pellets 1 cm

  6. Why Plastic Resin Pellets are found in the ocean? Urban runoff Ingestion by seabird Stranded Final Plastic Products Resin Pellets Resin Pellets Remelting Molding Chemical Plant Factory River Ocean Beach

  7. Contaminants found in marine plastic resin pellets Additive derived chemicals Bisphenol A Nonylphenol Sorption from ambient seawater Polycyclic aromatic hydrocarbons (PAHs) Polychlorinated biphenyl (PCBs) DDTs

  8. Nonylphenol concentrations in marine resin pellets on Japanese beaches Nonylphenol (ng/g-pellets)

  9. Contaminants found in marine plastic resin pellets Additive derived chemicals Bisphenol A Nonylphenol Sorption from ambient seawater Polycyclic aromatic hydrocarbons (PAHs) Polychlorinated biphenyl (PCBs) DDTs

  10. Adsorption of PCBs onto plastic resin pellets PCB concentration (ng/g-pellets)

  11. Applicability of beached plastic resin pellets to monitor coastal pollution by organic micropollutants Sorbed amounts of contaminants in pellets Contamination in the sea Monitoring Tool • Examination of regional difference in PCB concentrations in beached resin pellets. • comparison with that in the other monitoring media

  12. Sampling locations of beached resin pellets for monitoring of PCBs

  13. Sorting and analysis of beached resin pellets for monitoring of PCBs Sorting PE Yellowing and/or Fouled To exclude sporadic high concentrations of PCBs Multiple 10-pellet pools are analyzed for PCBs Median concentrations

  14. Analytical Method by near-infrared spectroscopy (PlaScan-SH) polyethylene : PE

  15. PCBs concentration in yellowing and/or fouled PE resin pellets from 47 Japanese beaches. Each pool is shown as a plot. PCBs concentrations (ng/g-pellet)

  16. PCBs concentration in yellowing and/or fouled PE resin pellets from 47 Japanese beaches. Median concentrations are plotted for PE pellets. PCBs concentrations (ng/g-pellet)

  17. Mussel Watch? (Mytilus galloprovincialis)

  18. PCB concentrations in yellowing and/or fouled PE resin pellets from 47 beaches and in mussels from 24 coasts in Japan. PCBs concentrations (ng/g-pellet) PCBs concentrations (ng/g-lipid)

  19. Relationship between median concentrations of PCBs in yellowing and/or fouled PE resin pellets and PCBs concentrations in mussels. PCBs in Mussel (ng/g-lipid)

  20. Conclusion • Beached resin pellets can be used for monitoring of PCBs in seawater. • At least 100 pieces per location are necessary for the monitoring. • Sorting of yellowing and/or fouled PE pellets is recommended for the monitoring

  21. Pellet Watch Global Monitoring of Persistent Organic Pollutants (POPs) Using Beached Plastic Resin Pellets More than 100 pieces (~ 200 pieces) per one location Air Mail Laboratory of Organic Geochemistry, Dr. Hideshige Takada, Tokyo University of Agriculture and Technology, Fuchu, Tokyo 183-8509, Japan

  22. Laboratory of Organic Geochemistry Dr. Hideshige Takada, Tokyo University of Agriculture and Technology, Fuchu, Tokyo 183-8509, Japan More than 100 pieces (~200 pieces) per one location Sorting PE, yellowing and/or fouled Analysis for POPs(PCBs, organochlorine pesticides) by GC-ECD, GC-MS more than 3 pools of 10 pellets to exclude sporadic high concentration Mapping POPs pollution Example of expected map of PCBs in beached plastic pellets • Sending the data via Internet to the collectors • Releasing the results on web

  23. Advantage of Pellet Watch Extremely low cost for sampling and shipping No special training is necessary for sampling World citizens can join Wide area (globe) can be monitored using minimal cost
