Washington: Exposure to Bisphenol A or BPA, a toxic chemical found in many consumer products, during early pregnancy may be linked to wheezing in children.BPA is found in products like plastic water bottles and food containers. It is present in more than 90 percent of the US population, suggesting widespread exposure.Penn State College of Medicine assistant professor of paediatrics Adam Spanier studied 367 children, 99 percent of whom were born to mothers with detectable BPA levels in their urine during pregnancy.These parents then reported any incidents of wheezing on a twice-yearly basis for three years. At six months, the odds of wheezing are twice as high for children with mothers who had higher BPA than those who had mothers with lower BPA levels.
