Study Links Common Plastic Chemical DEHP to Lifelong Anxiety in Male Rats
New research suggests that early life exposure to a common plastic chemical, DEHP, may lead to long-term behavioral changes. A study found that male rats exposed to DEHP shortly before and after birth exhibited significantly higher levels of anxiety as adults. These effects persisted even after the exposure period concluded, indicating potential lasting impacts on behavior.
A recent study has identified a potential link between early life exposure to a common plastic chemical and subsequent anxiety in adulthood. Researchers observed that male rats exposed to Di(2-ethylhexyl) phthalate (DEHP), a plasticizer, before and shortly after birth displayed elevated anxiety levels as adults.
DEHP is widely utilized in various products, including medical devices and children's toys. The study indicated that the behavioral effects, such as increased hesitancy to explore open spaces and prolonged periods of freezing, persisted long after the initial exposure to the chemical had ceased. These behaviors are recognized as classical signs of anxiety in rodents.
