Monitoring of environmental impacts of industrial sites wastewaters by freshwater diatoms

Summary

The ecological quality of rivers can be monitored using various bio-indicators, including diatoms. These microalgae, which are ubiquitous in aquatic ecosystems, are routinely used to assess nutrient and organic matter pollution levels in rivers. The aim here was to study the potential of this bio-indicator, this time for industrial pollution (mineral micropollutants, saline discharges, etc.). Fieldwork at different spatial scales (artificial river, watercourse near an industrial site, hydrographic basin) coupled with a solid bibliographical study identified several promising avenues and will lead to a scientific publication. We look forward to continuing our research!
