Low Phosphorus Levels Increase Toxicity of Cadmium in Algae Cells.

Wastewater Monitoring

The study looked at how different levels of cadmium, nitrate, and phosphate affect the growth and chlorophyll levels of a type of algae called Dunaliella salina. They found that high cadmium levels decreased chlorophyll fluorescence and cell density, while normal nitrate levels helped the algae tolerate cadmium stress. Low nitrate levels and phosphate limitation also negatively impacted growth and chlorophyll levels. The best conditions for Dunaliella salina were normal nitrate and high phosphate levels.
