XAD2

-based PAS

• XAD2 resin is exhaustively cleaned and then stored

• Samplers are mounted in a stainless steel mesh cylinders

• Dried under gently N₂ flow

• Stored in hermetically sealed SS containers

XAD2-based PAS

Side by side GAPS PUF-PAS – 6 sites • 2010-2014 – 2-3 resins/site

Project Aims

1. Assess the effectiveness of Stockholm Convention within

GRULAC region;

2. Gather new data for air (improve spatial and temporal resolution of data);

3. Assessment of local and global sources by deploying PAS

in agricultural, urban/industrial and low impact areas; 4. Produce long-term temporal studies

5. Consolidate/improve the research network;

6. Improve regional capability for sampling and analysis in air
