Here we report the presence of black carbon (BC) particles as part of combustion-derived particulate matter in human placentae using white-light generation under femtosecond pulsed illumination. BC is identified in all screened placentae, with an average (SD) particle count of 0.95\u2009\u00d7\u200910<sup>4<\/sup>\u00a0(0.66\u2009\u00d7\u200910<sup>4<\/sup>) and 2.09\u2009\u00d7\u200910<sup>4<\/sup>\u00a0(0.9\u2009\u00d7\u200910<sup>4<\/sup>) particles per mm<sup>3<\/sup>\u00a0for low and high exposed mothers, respectively. Furthermore, the placental BC load is positively associated with mothers\u2019 residential BC exposure during pregnancy (0.63\u20132.42\u2009\u00b5g per m<sup>3<\/sup>). Our finding that BC particles accumulate on the fetal side of the placenta suggests that ambient particulates could be transported towards the fetus and represents a potential mechanism explaining the detrimental health effects of pollution from early life onwards.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ambient black carbon particles reach the fetal side of human placenta.<br \/>\nHannelore Bov\u00e9, Eva Bongaerts, Eli Slenders, Esm\u00e9e M.
