9 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 GRULAC - Group of Latin American and Caribbean Countries in the United Nations PAS Passive Atmospheric Sampler
