Endocrine disrupting chemicals (EDCs) from the environment are associated with reproductive abnormalities (i.e. decreased sperm concentration; increased endometriosis) and alterations of cardiovascular system blood pressure risk coronary disease). Some phthalates esters have been identified as EDCs, for which inhalation is considered one routes exposure. However, only little known regarding inhalational exposure to EDCs via urban airborne particles. In present study, we report monthly concentration 8 phthalate measured in PM10 PM2.5 collected recovered during 7 months a highly populated area Mexico City. Using levels reported by automatized network environmental monitoring City sampling site, estimated people different ages gender. Two endocrine compounds, DEHP DnBP, were found on particles higher concentrations warmer year. The highest was (229.7μg/g particles) May 2013. After calculations atmosphere, using respiratory flow rate, determined males potentially exposed larger quantities DEHP, reaching up 18ng/8h April Despite seem be rather small, comprehensive characterization its presence necessary order evaluate overall these providing clear view children, adolescents pregnant women.
