1.0 Determination of trends in the ambient air Persistent Organic Pollytants (POPs) concentrations in the Pacific Islands Region using the polyurethane foam based passive air samplers.
The project involves the use and application of polyurethane foam disks (PUFs) as an air filter in the determination of the concentrations of POPs in ambient air. Emphasis is placed on the evaluation of the impact of the local primary point sources, secondary and diffusive sources as well as the long range transport (LRT) of these organic compounds. The air samplers will be used to test the levels of persistent organic pollutants (POPs) in the environment; POPs are poisonous chemicals that can cause cancer and birth defects. They last a long time in the environment and can be carried by wind and water. The pilot project on passive air sampling initially intends to acquire baseline data for the first 12 month, and with the availability of funding, should establish a regional POPs monitoring program to cover a number of regional countries.
The project is a collaborative initiative between the Research Centre of Excellence for Eco-toxicological Research (RECETOX) of the Masaryk University in the Czech Republic with IAS and funded by the United Nations Environment Programme (UNEP).

2.0 Levels of persistent organic pollutants and 2,2,4,4,- tetrabromodiphenylether (PBDE No. 47) in freshwater mussels (Batissa violacea) (kai) in Fiji Rivers and seawater shellfish Anadara antiquata (kaikoso) in Fiji coastal waters.
The research project involves a detailed investigation on the contamination of rivers and coastal waters of Fiji of POPs and PBDEs by the use of freshwater mussels and seawater shellfish as bio-indicators. These mussels and shellfish were chosen as bio-indicators since these were valuable daily food for coastal.rivers-side dwellers and also a major source of daily earnings for most Fiji families. Many of the agricultural activities in Fiji would se the rise in levels of pesticide residues in its rivers as well as the lagoons. Many of these toxic compounds are bio-accumulated within the tissues of biota to concentrations above the above ambient levels in the environment. Funding for the project was provided for by the University Research Committee.
Part of the analysis was carried out at the Orebro University in Sweden under Professor Bert van Bavel and Professor Gunilla Lindstrom.
