Shillong, October 1: A recent study has revealed that exposure to PFAS (per- and polyfluoroalkyl substances), a group of synthetic chemicals, may lead to delayed puberty in girls.
As per IANS, published in the journal Environmental Health Perspectives, the study highlights that PFAS chemicals are commonly found in various products such as cleaning agents, water-resistant fabrics (used in rain jackets, umbrellas, tents), and nonstick cookware.
According to Susan Pinney, the corresponding author of the study, delaying puberty in girls can result in adverse long-term health consequences, including a higher risk of breast cancer, renal disease, and thyroid disease. She emphasized that environmental exposures during puberty, including exposure to PFAS, can potentially have lasting health effects by extending the period of vulnerability.
To conduct the research, scientists from the University of Cincinnati in the United States enrolled 823 girls aged six to eight years. They closely monitored the girls with exams conducted every six to 12 months to track the onset of breast development and pubic hair growth.
The study revealed that 85 percent of the girls had measurable levels of PFAS, with over 99 percent having measurable levels of PFOA, one of the key PFAS compounds.
The research found that girls exposed to PFAS experienced an average delay in puberty of five to six months. However, some girls faced more significant delays, while others experienced no delay at all. The study’s authors expressed particular concern for those at the higher end of the delay spectrum.
Susan Pinney emphasized the persistence of PFAS chemicals in the environment, noting that it took a long time to recognize their toxicity to humans. She added that these toxins have become pervasive in our environment and will persist for an extended period.
