Abstract:
Analyzes of physico-chemical parameters make it possible to determine and know the level of contamination of seawater at the marina and fishing port of Mostaganem (the salamander). The presentation of this study is divided into different chapters, the first covering the different types of marine pollution and their effects on the aquatic ecosystem; the second chapter aims at a presentation of the port of Mostaganem with these three sites: entrance to the port, diesel station, inclined plane; the choice is made in view of the ecological and economic importance of the facade of the latter (boating and fishing) and in particular the damage caused by human activity (pollution). The third chapter is devoted to a bibliographical summary on the polluting elements recalling their major physicochemical characteristics. The fourth chapter is an enumeration for the different methods practiced for the measurements of several parameters which require a precision apparatus. The last chapter is the result given to establish the causes of pollution at the level of the three sites and the degree of contamination by the various discharges.
