Engineered Animals to Fight Mercury Pollution

A Macquarie University-led research showed that engineered zebrafish and fruit flies can break down methylmercury and remove it from their bodies as a less harmful gas. This breakthrough highlights the great potential of genetically modified (GM) animals for pollution control.

Methylmercury is one of the world's most dangerous pollutants that builds up in the environment and enters the food chain through contaminated seafood. When consumed, it can harm the brain and nervous system. Industrial activities, such as gold mining and coal burning, also contribute to mercury pollution.

“When we tested the modified animals, we found that not only did they have less than half as much mercury in their bodies, but the majority of the mercury was in a much less bioavailable form than methylmercury,” said Dr. Kate Tepper, lead author of the study. The researchers said extensive testing is needed to ensure its effectiveness and safety.
