  • Monitor trends in bioaccumulation – dioxin and furan monitoring in sediments and biological tissues.
  • Environmental Effects Monitoring – integrated assessments of pulpmill water and sediment quality, invertebrate communities, fish health, and sub-letahl effluent toxicity.
  • Inventory of dioxins and furans – compliance with the Stockholm Convention on persistent organic pollutants (POPs).
  • Capacity building – training in the collection, preparation and analysis of various environmental media and training in site identification and prioritization for remediation.
  • Health Risk Assessment - identifying environmental pathways and human exposure.

The key objective of the program is to improve the ability of government agencies in the South East Asia Region to manage POPsand POPs-like chemicals using a health risk-based approach. A second objective is to improve inter-governmental cooperation on hazardous chemicals issues in the region.

Coastal dioxin and furan monitoring programs
Since 1989, Hatfield has understaken annual dioxin and furan trend monitoring programs for the pulp and paper industry in British Columbia, Canada. Trends in the concentration of dioxins and furans in biological tissues and sediments were correlated to changes in effluent treatment and the bleaching process.
