What is it about?
Recently, algae have been used in bio remediation and to cleanup wastewater due to their high efficiency in absorbing both organic and inorganic pollutants, including dissolved nutrients, heavy metals, pesticides, toxic compounds and even radioactive materials. Almost all freshwater ecosystems depend on phytoplankton because they are producers and participate in the aquatic food chain; they are also useful for water quality assessment.

Why is it important?
Algae respond quickly to the pollution of the surroundings, manifested in the accumulation of high biomass that are easy to detect and sample. Presence of some algal species strongly correlated with the presence of specific types of pollutants, especially organic ones.
Perspectives
Due to their nutritional preferences and as the base of the food chain, algal indicators provide more distinctive information regarding ecosystem conditions compared to some known animal indicators. These ecologically relevant signals, which denote ecosystem changes, could then be used to differentiate and distinguish acceptable from unacceptable environmental conditions. Algal indicators are more cost-effective observation tool.
