N2 - A discussion is presented on the limitations for air monitoring studies around the Group of Latin American and Caribbean Countries (GRULAC), highlighting key issues requiring further attention, and reports on how a special initiative is addressing these limitations. Preliminary results are presented for the first reported data on organophosphorus flame retardant (OPFR) concentrations in outdoor air from the GRULAC region. At the majority of sites the concentrations and the profile of the OPFRs detected were similar with tris (chloroisopropyl) phosphate (TCPP) dominating (< MDL to 1280 pg/m3). However, the urban location at Concepción, Chile presented higher concentrations and a different profile with tris (2-butoxyethyl) phosphate (TBEP) dominating (mean 800 pg/m3 vs 80 pg/m3 at the other locations) –indicating different sources at this location. OPFRs, used extensively as flame retardants and plasticizers, are found ubiquitously in indoor environments yet only few studies report outdoor air levels. This preliminary study of only 7 sites highlights how extensive regional passive sampling networks (such as GAPS) can provide important new information to support risk assessment of these and similar chemicals. Finally, the various challenges with implementing a regional monitoring program are discussed, including harmonizing data from various monitoring programs for reporting to the GMP.
