Descriptions : | Bu çalışmada, İskenderun Körfezi'nin kıyısal zonundaki üç farklı istasyondan toplanan makroalg türleri (Jania rubens, Padina pavonia, Laurencia papillosa, Cystoseira corniculata) ve çökel örneklerinde Demir (Fe), Bakır (Cu), Kurşun (Pb), Çinko (Zn) ve Kadmiyum (CdD gibi ağır metallerin birikim düzeyleri incelenmiştir. Bu amaçla, makroalg ve sediment örneklerinde Fe, Cu, Pb, Zn ve Cd düzeyleri spektrofotometrik olarak ölçülmüştür. Makroalg örneklerinde ağır metal derişimleri sıralaması Fe Zn Pb > Cu Cd olarak, sediment örneklerinde ise Fe > Pb > Zn > Cu > Cd olarak belirlenmiştir. Ağır metal derişimleri J. rubens ve P. pavonia'da, L. papillosa ve C. corniculata'ya göre daha yüksek düzeyde bulunmuştur. Böylece sonuç olarak, İskenderun Körfezi'nde J. rubens ve P. pavonia'nın ağır metal birikimi itibariyle iyi bir gösterge oldukları; öte taraftan bu türlerin ağır metal kirliliği çalışmalarında gösterge tür olarak kullanılabilecekleri sonucuna varılmıştır
In this investigation, heavy metal pollution of coastal zone of İskenderun Bay was tried to determined by measuring the levels of Iron (Fe), Copper (Cu), Lead (Pb), Zinc (Zn) and Cadmium (Cd) in macroalge species (Jania rubens, Padina pavonia, Laurencia papillosa, Cystoseira corniculata) and sediment samples which were collected from at the three different station in the İskenderun Bay. For this purpose, heavy metal levels in macroalge and sediment samples were measured spectrometrically. In macroalge samples heavy metal concentrations decreased in the following order: Fe Zn Pb > Cu Cd, in sediment samples Fe > Pb > Zn > Cu > Cd. The concentrations of heavy metals were higher in J. rubens and P. Pavonia than in L. papillosa and C. corniculata. Thus, the macroalgae species, J. rubens and P. pavonia could be an indicator in terms of heavy metal accumulation in the İskenderun Bay and besides, it is concluded that these species could be used as a indicator species in heavy metal pollution studies
In dieser Untersuchung, Heavy-Metal-Verschmutzung der Küstenzone von İskenderun Bay wurde versucht, durch Messung der Pegel von Blei (Pb), Zink (Zn), Eisen (Fe), Kupfer (Cu) und Cadmium (Cd) bestimmt in Macroalge Arten (Jania Rubens, Padina Pavonia, Laurencia Papillosa, Cystoseira Corniculata) und Sediment zu Proben, die bei der drei verschiedene Station in der Bucht von İskenderun entnommen wurden. Zu diesem Zweck wurden spectrometrically Heavy-Metal-Ebenen in Macroalge und Sediment Proben gemessen. In Macroalge-Samples, die heavy Metal Konzentrationen in der folgenden Reihenfolge sank: Fe-Zn-Pb > Cu Cd, im Sediment Proben Fe > Pb > Zn > Cu > Cd. Die Konzentrationen von Schwermetallen waren im J. Rubens und s. Pavonia als L. Papillosa und C. Corniculata höher. So könnten die Makroalgen-Arten, J. Rubens und s. Pavonia Indikator in Bezug auf die Heavy-Metal-Ansammlung in der İskenderun-Bucht und neben, wird der Schluss gezogen, dass diese Arten als ein Leitarten in Heavy-Metal-Umweltverschmutzung-Studien verwendet werden könnten
