Abstract

Günümüz şartlarında, Çevre Kirlenmesi, toplum sağlığı yönünden önde gelen konulardan birini teşkil etmektedir. Suların kirlenmesinde bir kriter olması yanında, besin zincirine girerek insan vücudunda akümüle olması ve sağlığı bozması nedeni ile de Su ürünlerinde Cıvp rezüdüleri araştırdık. Karadeniz ve bu denize dökülen büyük nehirlerimizden birinden avlanılan balıklara ait 156 numunede; Thin Layer Chromatography metodunu uygulayarak % 44 oranında muhtelif konsantrasyon da Cıva rezüdüsü tesbit ettik.
Sakarya'dan yakalanan Yayın balıklarında kontaminasyon oranı % 60 ve kontamine balıkların % 13 de de Cıva rezüdü seviyesi 1,2 mg/kg. üstünde bulundu. Karadeniz'den yakalanan Kefal, istavrit, Kılıç ve Minek0D balıklarında kontaminasyon oram % 37 ve kontamine balıkların % 12,7 inde Cıva rezüdüsü 1,2 mg/kg. üstünde bulundu.
Tatlı su balıkları ile deniz balıkları arasındaki kontaminasyon seviyesi farkı X2 testi uygulanarak istatistikî yönden (P ç 0,001) ileri derecede önemli bulundu.

Abstract

In today's conditions, environmental pollution is one of the leading issues concerning public health. In addition to being a criterion in water pollution, the accumulation of contaminants in the food chain and their detrimental effects on human health prompted us to investigate mercury residues in aquatic products. In 156 samples of fish caught from the Black Sea and one of its major rivers, we detected mercury residues in various concentrations with a 44% prevalence using the Thin Layer Chromatography method.

In fish caught in Sakarya, contamination was observed in 60% of the samples, and in 13% of these contaminated fish, the mercury residue level was above 1.2 mg/kg. In fish caught from the Black Sea, such as Grey mullet, Horse mackerel, Swordfish, and Red mullet, contamination was detected in 37% of the samples, and in 12.7% of the contaminated fish, the mercury residue exceeded 1.2 mg/kg.

A significant statistical difference was found between contamination levels in freshwater and seawater fish (P < 0.001) when analyzed with the X2 test.
