Su ürünlerinde kadmiyumun biyobirikimi ve toksisitesi

Tüm ağır metaller kaçınılmaz bir şekilde toksiktirler. Kadmiyum yaşayan hiçbir canlı organizma için temel bir element değildir. Yumuşakçalar kadmiyumu serbest konsantrasyonlarda biriktirirler. Son yıllarda insanlar tüm dünyada yaygın olarak artan ve çeşitli kirleticiler tarafından oluşan deniz kirliliğinin farkına vardılar. Dünya çapındaki endüstrileşme sürekli artış gösterdikçe kadmiyum gibi aşırı toksik elementlere de ilgi sürecektir. Kadmiyum gibi ağır metallerin su organizmalarına etkilerini daha iyi anlayabilmek için, bu maddenin alımı, birikimi, saklanması ve atılması ile ilgili birçok kimyasal ve fizyolojik yöntemlerin anlaşılması çok önemlidir. Bu çalışmanın amacı, kadmiyumun biyoakümülasyon karakteristiğini ve su ürünleri üzerindeki toksisitesini aydınlatmaktır.

Bioccumulation and toxicity of cadmium in the water products

Bioaccumulaton and toxicity of cadmium in the water products. All heavy metals are among the most toxic and inevitable pollutants. Cadmium is not an essential element for any organism. Molluscs accumulate large concentrations of cadmium. In recent years, people have been concerned that marine pollution by various pollutants is slowly advancing in extensive areas all over the world. Cadmium is an extremely toxic element continuing concern because its environmental levels have risen steadily with continued worldwide industrialization. In order to understand better the impact of heavy metals, such as cadmium in aquatic organisms, it is important to understand the chemical and physiological processes that control their uptake, bioaccumulation, storage and elimination. The aim of this study is to clarify the charactheristics of cadmium and its bioaccumulation and toxicity in water products.
