The quantification of semi-volatile organic compounds with potential endocrine-disrupting activity contained in fine atmospheric particles (PM2.5) is essential to understand their temporal behavior, identify sources, and evaluate the health risks resulting from population exposure said compounds. Since information research outcomes regarding presence atmosphere developing countries are scarce, main objective this work was development a methodology devoted extracting, characterizing, quantifying, for first time Mexico, concentration levels three important groups (EDCs) bonded PM2.5 collected during year, namely: alkylphenols (4-n-nonylphenol (4NP) 4-tert-octylphenol (4tOP)); bisphenols (bisphenol A (BPA) bisphenol F (BPF)); natural synthetic hormones (17β-estradiol (E2), estriol (E3) 17α-ethinyl estradiol (EE2)). Further, priority polycyclic aromatic hydrocarbons (PAH) that also disrupt endocrine were analyzed. All determined by gas chromatography coupled tandem mass spectrometry, analyzed different climatic seasons. Cold-dry (CD) season displayed higher 4NP, bisphenols, (between 0.71 1860 pg m−3 (BPA)), as well PAH concentrations (9.12 ng m−3). Regarding effects, alkylphenols, quantified had value equivalent (EEQE2) between 0.07 0.17 m−3. did not have carcinogenic mutagenic risk BaP(PEQ) < 1 These results can be used policymakers design strategies air pollution control.
