Phytoremediation
Algae and salt-tolerant plants growing in coastal ponds or runoff channels could naturally strip the fertilizer pollution that turns your local lake green and kills fish — making them a cheap, living alternative to expensive water treatment.
When too many nutrients like nitrogen and phosphorus end up in water — often from fertilizer runoff — it causes algae blooms that choke out other life. This study tested whether certain seaweeds and a hardy land plant that tolerates salty conditions could soak up those nutrients like living sponges. By comparing different amounts of these plants, the researchers were looking for the sweet spot where cleanup is most efficient.
Key Findings
Four seaweed species and one halophyte (salt-tolerant plant) were evaluated for their ability to remove excess nutrients from enriched water bodies.
The study used a dosage-dependent design, meaning different quantities of each plant were tested to determine optimal biomass for maximum nutrient removal.
Growth rate was measured alongside nutrient absorption, indicating the researchers assessed whether the plants could sustain themselves while performing bioremediation.

Researchers tested four seaweed species and one salt-tolerant land plant to see how well they absorb excess nutrients from polluted water, and whether using more plants produces better cleanup results. The goal was to identify the most efficient natural filters for nutrient-laden waterways.

Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other mari...
