By definition, eutrophication is explained as the participation of essential nutrients such as phosphorus, sulfur and nitrogen into the water cycle as natural and anthropogenic resources, and the deterioration of water quality in lakes or any large aquatic ecosystems. As a result of eutrophication, the water forms a dark layer on the surface due to the excessive proliferation of algae, significantly reducing sunlight reaching the phytoplankton below and obtaining of dissolved oxygen.

  In this study, the effects of nutrients contained in Sahara dust on eutrophication were examined by conducting experiments on 3 types of algae (Arthrospira platensis, Chlorella vulgaris and Scendenesmus) under laboratory conditions to test the relationship between eutrophication and airborne desert dust.

As a result, the positive effects between eutrophication and desert dusts have been clearly demonstrated, and it has been revealed that sulphate, unlike phosphate, is the main cause of eutrophication in water.
