Özet

Metal pollution was assessed in bryozoan species at seven sampling stations in ports and marinas along the eastern coast of the Aegean Sea. This study area's primary sources of metal contamination were urbanisation and antifouling paints. Bugula neritina and Amathia verticillata were identified as the most abundant species. A. verticillata is considered an alien species, while B. neritina is classified as a cryptogenic species in the Mediterranean Sea. In contrast, Cradoscrupocellaria bertholletii, a native species observed at one station, exhibited the lowest mean concentrations of lead, cadmium, and vanadium. The levels of lead (Pb), cadmium (Cd), copper (Cu), vanadium (V), and zinc (Zn) in bryozoans did not show significant differences among species or sampling seasons, except for Pb. However, Cu and Zn concentrations varied significantly among different sampling stations. A strong correlation between the levels of copper and zinc in the sediment suggests that these elements originate from the same source, specifically antifouling paint. Additionally, cadmium and lead levels were significantly correlated with those found in both bryozoans and sediments. Bugula neritina and A. verticillata demonstrated tolerance to anthropogenic disturbances in ports and marinas, making them suitable organisms for biomonitoring copper and lead pollution.
