Whether the quantity of BPA that leaches into food and beverages through container, represents an environmental risk is a subject of argument.

“Our primate model indicates that BPA could negatively affect brain function in humans,” study investigator Tibor Hajszan said.

Hajszan and colleagues examined the effect of continuous exposure to BPA at a daily dose recommended by US Environmental Protection Agency’s (EPA) according to current reference safe daily limit that is 50 micrograms/Kg in young adult African green monkeys.

Research proceedings show that, BPA completely deteriorate the structure of some nerve connections in two important regions of the brain which include hippocampus and prefrontal cortex.

These findings have “thoughtful implications,” the investigators maintain, given the critical role of these nerve associations in cognition and mood.

“Based on these findings, we think the EPA may wish to consider lowering its ‘safe daily limit’ for human BPA consumption,” Hajszan said
