International efforts to manage POPs include the global treaty of the Stockholm Convention (SC) onPOPs (signed in 2001 and came into force in 2004) that aimed to eliminate and reduce the release of POPs intothe environment1. Under the SC, the Global Monitoring Plan (GMP) was implemented to facilitate the evaluationof the effectiveness of the convention through monitoring of POPs in core media of air and human tissues. Aguidance document for the GMP was also prepared by UNEP and recommends the use of passive air samplersfor addressing data gaps on POPs. The first report of the GMP in 2009 identified significant data gaps for POPsin air in the GRULAC region (GRoUp of Latin American and Caribbean Countries)2.The Latin American Passive Atmospheric Sampling Network (LAPAN) has been set up to enablestudies of long-term spatial and temporal trends of atmospheric contaminants on a regional scale in a sustainable,cost-effective way. It will also allow signatory countries to comply with SC demands on the identification ofmain sources and provide comparable data of POPs contamination. This will help to identify areas of concernand to evaluate the effectiveness of the control actions adopted by the member countries of this convention toeliminate the release of POPs to the environment. Nowadays, researchers from Argentina, Bolivia, Brazil,Colombia, Chile, Ecuador, Peru, Uruguay, Venezuela and Honduras are collaborating with the LAPAN network.The XAD2-based passive atmospheric sampler has the advantage of being cheaper and easier to run, making itpossible to increase the present spatial and temporal resolution run by Global Atmospheric Passive Sampling(GAPS) Network at Latin America. In addition to POPs, other contaminants found in the vapor phase are beingmeasured whenever possible (i.e. current used pesticides, PAHs, new POPs, contaminants of emerging concern).
