Specifically, the team was investigating the alarming frequency of congenital neural tube defects, in which portions of an infant\u2019s brain, skull, or spine are missing or do not connect properly. Most babies born with this condition live only a few weeks.<\/p>\n<p>In the U.S., for every 10,000 live births, there are 7.5 infants with neural tube defects. In Shanxi province, that number is 18 times higher: 140 infants. \u201cWe wanted to understand what\u2019s really behind the problem,\u201d says Tong, who previously worked at Peking University in Beijing. \u201cWe wanted to find out what chemicals caused this.\u201d<\/p>\n<p>Over a 10-year period, the researchers gathered placentas from 80 stillborn or newborn infants in Shanxi with the disorder. Based on their analysis, they confirmed that those infants had been exposed in utero to significant levels of pesticides, industrial solvents, and especially polycyclic aromatic hydrocarbons (PAHs), which are released into the air when fossil fuels are burned. In Shanxi, abundant coal is used for power plants as well as for home cooking and heating. \u201cWe found higher concentrations [of the chemicals] in the placentas of infants with the birth defects\u201d than in other infants, explains Tong, who says there is a \u201cclear association\u201d between the environment the mother is exposed to and birth outcomes.
