What is it about?
What is it about? This study delivers the first comprehensive regional overview of heavy metal contamination in North African inland waters (Algeria, Morocco, Tunisia, and Egypt). By analyzing data from 38 different scientific studies, we mapped out the presence of toxic elements in both surface waters and sediments. The findings reveal that dangerous contaminants—specifically arsenic, cadmium, mercury, nickel, and lead—frequently exceed safety thresholds, posing a direct threat to aquatic life and ecosystems.

Why is it important?
Until now, data on water pollution in North Africa was highly fragmented, making it difficult to understand the scale of the problem. Our work connects these pieces to show how rapid urbanization, intensive agriculture, and industrial activities are putting these vital aquatic systems at risk. By identifying the most critical pollutants, this review provides a crucial baseline for policymakers and scientists to coordinate monitoring efforts, protect biodiversity, and safeguard public health.
Perspectives
As researchers in life and environmental sciences, we observed that data on water contamination in North Africa was scattered and difficult for policymakers to use. We wanted to build a unified regional map to show the true scale of the problem. Moving forward, our goal is to advocate for standardized water-quality monitoring across Algeria, Tunisia, and Egypt. We hope this work inspires collaborative cross-border environmental policies to protect our shared aquatic ecosystems, biodiversity, and public health before the damage becomes irreversible.
