Concentrations of Cr, Cd, Cu, Zn and Fe in crab Charybdis longicollis and shrimp Penaeus semisulcatus from the Iskenderun Bay, Turkey

Abstract

Copper, chromium cadmium, iron and zinc concentrations were determined in marine crab Charybdis longicollis and marine shrimp Penaeus semisulcatus in order to assess the impact of industrial activities and the sinking of M/V Ulla ship. Liver, gill and muscle sample solutions prepared analyzed using the atomic absorption spectrophotometry technique. The order of the metal concentrations found in muscle of crab was: Cu>Cr>Fe>Zn>Cd, while in muscle of shrimp the order was different: Cr>Cu>Zn>Fe>Cd. The highest Cu, Cr, Cd, Fe and Zn concentrations were found in the liver, and this was followed by the gill and muscle in both species. The levels of all metals in a given tissue were always higher in C. longicollis than in P. semisulcatus. Metals in both species show seasonal variations. In both species the highest concentrations were detected for all metals in summer.

Accumulation of Cd, Cu, Pb, and Zn in water, sediments, and mangrove crabs (Sesarma mederi) in the upper Gulf of Thailand

“…Montes Nieto et al 47 detected metal accumulation in the gill of Carcinus maenas in Spain and they found a correlation between metal accumulation and degree of industrialization. Firat et al 48 found high concentrations of metals in shrimps (Penaeus semisulcatus) in Iskenderun Bay, Turkey, mainly caused by the wastewater drainage from the city nearby. This excessive metal concentration in river mounts of the upper gulf of Thailand may be caused by agricultural and industrial wastewater coming from upstream areas together with municipal wastewater from the cities nearby 49 .…”

Heavy metals in Patella caerulea (Mollusca, Gastropoda) in polluted and non-polluted areas from the Iskenderun Gulf (Mediterranean Turkey)

“…Letters a, b, and c show differences among tissues. Data shown with different letters are statistically significant at p < 0.05 * p < 0.5; * * p < 0.1 (Student's t test); statistical differences between stations agricultural and industrial effluents and harbor operations were the main sources of marine pollution problems in this area (Yilmaz 2003;Cogun et al 2005;Türkmen et al 2005;Firat et al 2008). …”

“…Numerous studies on heavy metal pollution from a wide spectrum on anthropogenic sources in various areas of Iskenderun Gulf have been carried out over the years (Kargin 1996;Yilmaz 2003;Cogun et al 2005;Türkmen et al 2005;Doygun and Alphan 2006;Firat et al 2008;Yüce and Alpar 1994).…”

Distribution of trace elements in tissues of shrimp species Litopenaeus vannamei (Boone, 1931) from Bahia, Brazil

“…Its concentrations ranged from: 24.8-33.9 μg g -1 in muscle, 81.9-152.0 μg g -1 in viscera, 55.9-77.6 μg g The gills, present in the visceral samples, are structures with essential function in crustacean's respiration. They can potentially accumulate trace elements by absorption through the gills or by consumption of contaminated sediments (Firat et al, 2008). The metal concentrations in the gills reflect the metal concentrations in water (Yilmaz, 2003).…”
