Even a little air pollution may have long-term health effects on developing fetus

 Even small amounts of air pollution appear to raise the risk of a condition in pregnant women linked to premature births and lifelong neurological and respiratory disorders in their children, new Johns Hopkins Bloomberg School of Public Health research suggests.
Fine particles from car exhaust, power plants and other industrial sources are breathed into the lungs, but the scientists have now found evidence of the effects of that pollution in the pregnant women's placentas, the organ that connects her to her fetus and provides blood, oxygen and nutrition. They found that the greater the maternal exposure to air pollution, the more likely the pregnant women suffered from a condition called intrauterine inflammation, which can increase the risk of a number of health problems for her child from the fetal stage well into childhood.
