Abstract:		"A special initiative in the Global Atmospheric Passive Sampling (GAPS) Network was implemented to provide information on new and emerging persistent organic pollutants (POPs) in the Group of Latin America and Caribbean (GRULAC) region. Regional-scale atmospheric concentrations of the new and emerging POPs hexachlorobutadiene (HCBD), pentachloroanisole (PCA) and dicofol indicators (breakdown products) are reported for the first time. HCBD was detected in similar concentrations at all location types (<20-120?ª+pg/m(3)). PCA had elevated concentrations at the urban site Concepcion (Chile) of 49-222?ª+pg/m(3), with concentrations ranging <1-8.5?ª+pg/m(3) at the other sites in this study. Dicofol indicators were detected at the agricultural site of Sonora (Mexico) at concentrations ranging 30-117?ª+pg/m(3). Legacy POPs, including a range of organochlorine (OC) pesticides and polychlorinated biphenyls (PCBs), were also monitored to compare regional atmospheric concentrations over a decade of monitoring under the GAPS Network. gamma-hexachlorocyclohexane (HCH) and the endosulfans significantly decreased (p?ª+
