Excerpt from: Personal care ingredient linked to ADHD
A new study has linked phthalates, a substance used in some shampoos, lotions, air fresheners and children’s toys, with attention-deficit hyperactivity disorder. Although research on the health effects of phthalates (pronounced “thalates”) has been somewhat inconsistent, the latest study, published in Biological Psychiatry, adds to troubling findings about the chemical.
“These data represent the first documented association between phthalate exposure and ADHD symptoms in school-aged children,” Yun-Chul Hong, MD, PhD, senior author of the study, said in a statement. He and his colleagues came to their conclusions after measuring urine phthalate concentrations and evaluating ADHD symptoms in 261 Korean children, age 8 to 11 years. They found that the higher the concentration of phthalate metabolites in the urine, the worse the ADHD symptoms.
Some studies to date on phthalates have linked the chemical to hormone disruptions, birth defects, asthma and reproductive problems. Other studies have found no significant association between phthalate exposure and health risks.
