More than eleven percent of children born in the United States have Attention Deficit Hyperactivity Disorder. In a study conducted by Columbia University, children exposed to air pollution during pregnancy were five times as likely to have this disorder by the young age of nine. “During the fetal period and early childhood years, the brain is rapidly developing and vulnerable to neurotoxic insults that may manifest as adverse outcomes in childhood and adulthood.” Previous to this study, air pollution has been linked to other severe issues such as developmental delays, reduced IQ and symptoms of anxiety depression, and even cancer.

This article suggested that air pollution has a direct correlation with children being born or obtaining Attention Deficit Hyperactivity Disorder at a young age. This study was conducted using only United States born children living in urban areas whose parents were nonsmokers. These figures are extremely alarming and further goes to show the danger of air pollution in today’s society. With the rate of this disorder being five times as likely to occur for children whose parents work in urban areas in the United States, the effects on Children living in India and China (world pollution leaders) is extremely scary.
