Acceso AbiertoContaminantes orgánicos persistentes (COPS) en leche materna de centros urbanos de la provincia de Buenos Aires(2012) Della Ceca,Lara; Migoya, Carolina; Capelletti, Natalia; Gómez, Graciela; Arozamena, Diego; Sobral, Madelón; Piñero, Julia H.; Soimer, Marisa; Bosco, Nerisa; Pérez, Elvira; Gluzman, Osvaldo; Rosa, María A.; López, Mariela; Colombo, Juan CarlosDue to their chemical persistence and high lipophilicity, persistent organic pollutants (POPs) have a tendency to accumulate and biomagnify in the food chain. Because of its easy and noninvasive collection, and high fat content, human milk, is a good indicator of these residues in human populations. The aim of our study was to evaluate human exposure to POPs (PCBs, DDTs and its metabolites, α, β y γ HCHs, CHLDs:\nheptachlor, heptachlor epoxide, trans and cis chlordanes and nonachlors) in 59 human milk samples collected during 2010-2011 in Punta Lara, Ensenada, Florencio Varela and Capital Federal.\nHuman breast milk was collected with manual breast pumps, centrifuged to separate the cream that was freeze-dried and ultrasonically extracted with petroleum ether. The extracts, previously treated with sulfuric acid to eliminate lipids, were cleaned up by silica gel chromatography and analyzed by gas chromatography.
