Bird brains shrink from exposure to contaminants

e able to attract any females."

These effects were most prominent in the males, some of which experienced up to a 30 per cent reduction in brain region size compared to males at lower DDT exposure levels.

Whether this also applies to other animals and humans is unclear because there is not yet a strong understanding of how these chemicals in the environment affect the brain, but it is possible that humans exposed to similar levels of DDT will also be at risk of neurological damage.

"The take-home message is that people need to be more cognizant of their use of pesticides and herbicides," said Iwaniuk. "People need to be careful about using chemicals in their homes or farms. Who knows the effects these will have down the road."
