Trace metal accumulation in tissues of wedge clams from sandy habitats of the Bulgarian Black Sea coast

چکیده
The aim of the present study was to carry out an initial screening trace metals bioaccumulation in soft tissues wedge clam ( Donax trunculus Linnaeus, 1758) from different localities Bulgarian Black Sea coastal area and evaluate bioindicator potential this species. Wedge clams were collected June September 2020 sublittoral sandy habitats at coast. Soft individual digested with nitric acid followed by ICP-OES analytical determination. content differed significantly amongst localities. Higher metal Sveti Vlas, Shkorpilovtsi, Slanchev Bryag, Ahtopol Kranevo. highest values lead (Pb) (2.51 mg/kg) cadmium (Cd) (0.32 found samples Vlas concentration copper (Cu) (34.12 mg/kg), iron (Fe) (269.52 nickel (Ni) detected Shkorpilovtzi. Maximum chromium (Cr) (0.58 together high Fe. zinc (Zn) (18.04 Cr Fe measured Irakli. In conclusion, known have higher inflows touristic pressures, i.e. Varna, Shkorpilovtzi, Bryag accumulated elements their tissues. Only few significant seasonal differences observed variations probably connected hydrological parameters ecosystems. D. is a suitable for assessment monitoring pollution environment.

The contamination status of trace metals in Sinop coast of the Black Sea, Turkey
The concentrations of some heavy metals in sediment from the Sinop coasts of the Black Sea were measured to monitor metal pollution in 2013. The distribution of the heavy metals in sediments of the Black Sea shows a variable pattern. The objectives of the present study were to elucidate the distribution heavy metals such as Cu, Pb, Zn, Ni, Mn, Fe, As, Cd, Cr, Hg and Co in sediment from Sinop co...
متن کاملFatty acids composition of macroalgae from Bulgarian Black Sea coast
Lipids and fatty acids (FA) composition of three Black Sea macroalgae Cladophora vagabunda, Ceramium rubrum and Cystoseira barbata were studied. Fatty acids composition was analyzed by GC/MS. Total lipids content varied widely among the species and ranged between 0.66 and 0.98 g per 100 g fresh weight. Generally, saturated fatty acids were major components (62–71%), with 16:0 as the most abunda...

Biomonitoring of trace metal bioavailability in the barnacle Amphibalanus improvisus along the Iranian coast of the Caspian Sea
The fouling barnacle Amphibalanus improvisus is a cosmopolitan biomonitor of trace metal bioavailability in coastal waters of reduced salinity such as estuaries or the Baltic Sea. Bioavailability of Ag, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn to A. improvisus was investigated in July 2014 at 15 sites along the Iranian coast of the understudied, yet biologically unique, Caspian Sea. In gene...
