University of Queensland study finds 98% of Moreton Bay covered in mud post-2022 flood, creating a 'dead zone'.

Mud contains clay, organic matter, and nutrients, altering water chemistry and releasing nitrogen, threatening the ecosystem.

Researchers call for urgent restoration to prevent irreversible ecosystem damage, focusing on the Brisbane River catchment.

Significant microplastic pollution discovered, with volumes comparable to three Olympic pools, endangers marine life.

Findings on Moreton Bay's condition published in the peer-reviewed Science of the Total Environment journal.
