Öz

Biyolojik birikim, biyolojik artış
kabiliyetleri ve metabolik faaliyetler sonucu vücuttan atılamamaları sebebiyle
ağır metaller, kimyasal su kirliliğinin en tehlikeli boyutlarını oluşturan
maddelerdir. Bu çalışmada kadmiyum, bakır, çinko, manganez, nikel, demir ve
kurşun gibi ağır metallerin genel özellikleri, kaynakları, balıklar tarafından
alınımı, ağır metal seviyelerinin belirlenmesi ve balıklar ve diğer sucul
organizmalar üzerine olan etkileri ile ilgili çalışmalardan literatür derlemesi
yapılmıştır. İncelenen çalışmalar göstermiştir ki ağır metaller balıklarda
oldukça şiddetli olumsuz etkiler oluşturmakta, balık sağlığını ve ekosistemi
tehlikeye atmakta ve ağır metal içeren balıkların tüketimi sonucu insan
sağlığında da ciddi tehlikeler meydana getirebilme potansiyeline sahiptir.

EFFECTS OF HEAVY METALS ON FISH

Öz

Heavy metals are matters that form the most dangerous
side of chemical water pollution due to their ability to bioaccumulate and
biomagnify and can not be eliminated from the body by metabolic activites. In
this study literature is reviewed by examining studies on general characteristics
and sources, uptake by fish, concentration evaluations and effects on fish and
other aquatic organisms of heavy metals such as cadmium, copper, manganese,
nickel, iron and lead. Studies examined showed that heavy metals cause severe
damage on fish thus endanger fish health and ecosystem and constitute respectable
risks for human health via consumption of heavy metal contaminated fish.
