A study found that a common plastic chemical called DEHP can cause lifelong anxiety in rats. The research suggests that exposure to this chemical before birth could have similar effects on humans.

Scientists studied the effects of a widely used plastic chemical called di-(2-ethylhexyl) phthalate (DEHP). They found that male rats exposed to DEHP during early development showed higher levels of anxiety as adults. This is concerning because it means that exposure to this chemical before birth could potentially cause long-lasting behavioral changes in humans too.

The researchers tested the rats' anxiety by using an elevated plus maze. The maze has two open arms and two enclosed arms, which allows scientists to measure how often the rats enter each type of arm and how much time they spend there. They found that rats exposed to DEHP spent less time exploring the open arms and more time in the enclosed arms.

The good news is that treating the rats with GABA agonists or testosterone reversed the effects of DEHP exposure. This means that these treatments could potentially counteract the behavioral changes caused by early DEHP exposure.

This study shows that our environment can have a lasting impact on our behavior and mental health. As we learn more about the effects of chemicals like DEHP, we can take steps to reduce our exposure and protect ourselves from potential harm.

Why It Matters
