Released when things arent burned pletely, this pollution is known as polycyclic aromatic hydrocarbons, or PAHs. The biggest sources of these PAHs: the burning of fossil fuels, wood and trash. Frederica Perera works at Columbia Universitys Mailman School of Public Health is New York City. She researches how exposure to things in the environment affects childrens health in a new study, she and her team studied the exposure to air pollution of 233 nonsmoking pregnant women in New York City.

The reason Any PAHs in a womans blood would also be available to the baby in her womb. Nine years later, the researchers investigated signs of attention problems in those children, now age 9. They asked each childs mother a series of questions. These included whatever her child had problems doing things that needed sustained(长期的)mental effort, such as homework or games with friends.
