Assessment of mineral element accumulation in plants and soils exposed to industrial pollution in the Gabes Gulf, Tunisia.

Phytoremediation
PubMedSame industrial contamination that concentrates heavy metals in wild coastal plants can also affect food crops grown in nearby soils — meaning pollution from distant factories can quietly enter the food chain long before it reaches your plate.
Scientists studied three wild plants growing near a chemical factory on the Tunisian coast to see how much toxic metal pollution they were soaking up from the soil. They found that the plants closest to the factory had the highest levels of harmful metals, and that leaves were the main place these metals ended up inside the plant. One species — a sea rocket plant — was so good at absorbing these metals that researchers think it could be used to help clean up contaminated land naturally.
Key Findings
Heavy metal accumulation was highest in plants at station S1, located 0 km from the industrial discharge point, confirming a clear distance-dependent contamination gradient.
Leaves were identified as the primary destination for mineral compounds across all three plant species, suggesting above-ground tissue poses the greatest risk for herbivores and the food chain.
Cakile maritima (sea rocket) showed the greatest overall accumulation capacity among the three species, making it a candidate for phytoremediation in polluted coastal zones.

Researchers found that plants growing near a chemical plant in Tunisia's Gabes Gulf are absorbing dangerous levels of heavy metals from polluted soil, with one coastal plant species showing enough uptake capacity to potentially be used as a natural cleanup tool.
