The seasonal variation of heavy metals in the suspended particulate material in the Iskenderun Bay (North-Eastern Mediterranean Sea, Turkey)

İskenderun Körfezi’nden Ağustos 2001 ve Temmuz 2002 tarihleri arasında beş istasyondan askıdaki katı maddede kadmiyum, demir, bakır, kurşun, çinko kobalt, krom, alüminyum, mangan ve nikelin dağılımları aylık olarak incelenmiştir. Ağır metal konsantrasyonlarındaki değişimler genel olarak önemli derecede farklı bulunmuştur. Genel olarak körfezin kendini çevreleyen yerleşim bölgelerinden kaynaklanan endüstriyel, tarımsal ve evsel ağır metal kirliliğinden etkilendiği anlaşılmaktadır. Bu sonuçlara göre, ekosistemdeki biyolojik çeşitlilikte göz önüne alınarak, körfezdeki ağır metal kirliliği tehdidini önlemek için, en kısa zamanda koruyucu önlemlerin alınmasının kaçınılmaz olduğu düşünülmektedir.

İskenderun Körfezi' nde (Kuzey Doğu Akdeniz, Türkiye) askıdaki katı maddede ağır metallerin mevsimsel değişimi

Variations of cadmium, iron, copper, lead, zinc, cobalt, chrome, aluminum, manganese and nickel in the suspended particulate material were examined monthly at five stations in Iskenderun Bay from August 2001 to July 2002. Generally, the variations in concentrations of the heavy metals were found significantly different. The bay has been affected by industrial and agricultural heavy metal pollution from the surrounding facilities and domestic effluents from the cities. According to these results, to prevent this heavy metal pollution threat in Iskenderun Bay, taking into consideration the biodiversity in this ecosystem, it is thought that it is inevitable that protective measurements must be started as soon as possible.
