| One of the main antrophic contamination problems on coastal environments is associated directly with the increasing amount of nutrients carried by the rivers and by urban runoff, which can hold a great number of microbial and algae population. This problem called sea coast eutrophication, stimulates primary production and in more severe cases leads to visible algae blooms, algae foams, excessive growth of benthic algae and massive population of submerged and floating macrophytes. It has been demonstrated that cases of algae blooms and associated toxicity affecting marine biota and people often occur on euthrophic coastal areas. The main goal of this research was first to analyze the structure and dynamics of phytoplankton, pointing out those harmful... |
