Freshwater Sponges: Nature’s Biofilters Against Toxic Metal Pollution
Recently, scientists highlighted the role of freshwater sponges and their associated microbes in tackling heavy metal pollution, offering a nature-based solution for cleaner aquatic ecosystems.
Key Scientific Findings
- Bioindicators of Pollution: Sponges accumulate significantly higher levels of toxic metals like arsenic, lead, and cadmium than surrounding water.
- Bioaccumulation Ability: Their strong metal-absorbing capacity makes them effective indicators of water quality.
- Unique Microbial Communities: Sponge-associated bacteria are distinct from free-living microbes in water and are shaped by habitat and species.
What are heavy metals?
- Heavy metals are elements with relatively high atomic weight and density, generally exceeding 5 g/cm³. Common examples include lead (Pb), arsenic (As) and ....
