A PRELIMINARY STUDY ON MACRO-LITTER POLLUTION ON BEACHES ALONG AÏN EL TURK BA Y (WESTERN MEDITERRANEAN)

Marine anthropogenic litter is one of the most important environmental problems that affect directly and indirectly all marine ecosystems. A lot of efforts are made to reduce the litter pollution in oceans, and, in this way, to reduce their negative effects on the marine biota. This study provides information about the quantities of marine litter found on 10 beaches situated along the occidental coast of Algeria. A total of 14537 items were collected throughout Ain El Turk beaches. From this litter, 93% were plastics and the remaining 7% were represented by rubber, glass and metal. The results highlight a heterogeneous distribution along the coastal beaches, with higher concentrations at some beaches rather than others, as well as the west coast, which seems more affected compared to the east coast. We notify that the litter has the tendency to accumulate in the upper levels of the beach, which confirms that these beaches are exposed to litter from land-based sources rather than from maritime activities.
