Metal(loid) accumulation and ecotoxicological assessment in cartilaginous fishes from the Northeastern Mediterranean
Çiftçi, Nuray | AYAS, Deniz
The present study was conducted with the objective of ascertaining the levels of selected metal(loid)s in the muscle, liver, spleen, kidney, stomach, intestinal, and gonad tissues of seven distinct cartilaginous species sampled from Northern Cyprus. This initiative was undertaken to address the dearth of metal bioaccumulation data for cartilaginous species and to elucidate the impact of metal pollution on these species, which are distinguished by their limited reproductive capacity. The samples were obtained from discarded species captured during commercial fishing activities. The metal concentrations in these tissues were subsequently determined using Inductively Coupled Plasma Mass Spectrophotometry (ICP-MS). The results indicated that the kidney tissue of Squalus blainville exhibited th...

The aim of the present study was to determine the levels of cadmium, copper, zinc and chromium in the liver, gill and muscle tissues of some pelagic, benthopelagic and benthic fish species caught from Mersin Gulf and sold at Karaduvar Harbor. Pelagic species Sardinella aurita (Clupeidae), Liza ramado (Mugilidae), benthopelagic species Diplodus annularis (Sparidae) and benthic species Solea lutea (Soleidae) and Umbrina cirrosa (Sciaenidae) were selected as the study material. Atomic absorption spectrophotometric methods were applied in determining the tissue levels of metals. Metal levels showed tissue-dependent changes in the species studied. Pb and Cr levels were below detection limit; hence no comparison was made among the tissues. Cd, Cu and Zn levels were highest in the liver tissues a...
