Aspetti dell’ecologia dei sistemi acquatici della Sardegna e loro principali problematiche

Eutrophication and Harmful Algal Blooms (HABs) are discussed in this paper as two of the main environmental issues of aquatic ecosystems of Sardinia. Eutrophication is caused by increased nutrient concentrations (largely nitrogen and phosphorous) in water bodies, which stimulate algal growth and lead to degraded water quality and impairments of aquatic ecosystems. It is the major issue of Sardinian reservoirs and lagoons. The HABs, which are often linked to eutrophication, are events that produce damage to the environment and/or risk for the economic human interests. Different typologies of HABs are signaled along Sardinian coast.
