    Acute toxicity of heavy metals to Hyale crassipes (Heller, 1866) in the Black Sea (2021)

    Description: Acute toxicity tests were performed on Hyale crassipes from Karakum shores of Sinop Peninsula in the Black Sea. 24, 48, 72 and 96-h LC50 values were estimated for copper, cadmium and zinc using static bioassay method. This study was the first toxicity study with Hyale crassipes and showed that the species was very sensitive to metals. The results indicated that Cu was more toxic to the amphipods followed by Cd and Zn. Clearly, Hyale crassipes has potential as test species for toxicity studies in Turkish waters.

    Metal levels in the striped venus clam Chamelea gallina (Linnaeus, 1758) from the southern Black Sea (2021)

    Description: The concentration of Hg, Cd, As, Pb, Cu, Zn and Fe in whole soft tissuesof the striped venus clam, Chamelea gallina, from the Black Sea coast has beendetermined by using Inductively Coupled Plasma – Mass Spectrometer (ICP-MS) formonitoring metal pollution of coastal water. Hg was not detected in C. gallina and Zn isseen to be the most abundant of the metals examined. Metal concentrations are lowerthan the maximal permissible quantities for human food as mentioned by the EuropeanCommission and Turkish Food Codex. The heavy metal concentrations in C. gallinaindicate that consumers of this seafood are not exposed to the risk of heavy metalpollution.

    Toxic metals in Nereis diversicolor Müller, 1776 from inner shores in Sinop peninsula of the Black Sea as bio-indicator species (2021)
    In:  pjms_ku@yahoo.com | http://aquaticcommons.org/id/eprint/26617 | 25017 | 2019-06-05 06:04:00 | 26617 | University of Karachi. Marine Reference Collection and Resource Centre

    Description: The concentrations of Cd, Hg and Pb in the whole parts of the worm Nereis diversicolor collected from the Turkish Black Sea coast have been measured by ICP-MS (Inductively Coupled Plasma -Mass Spectrometer) for monitoring metal pollution in 2015. Seasonal differences in the amounts of Cd, Hg and Pb in the sediment were not significant. The amounts of Pb were found to be higher in sediment than those of N. diversicolor. On the other hand Cd and Hg amounts in the worms were higher than the sediment. However, there were significant differences in toxic metal levels between sizes of N. diversicolor. Larger specimen accumulated less toxic metal. Cd had the highest CF mean followed by Hg and Pb showed the lowest CF value. It is concluded that the worm N. diversicolor are suitable biomonitors to assess changes in metal pollution in this coastal area of the Black Sea.

    A preliminary study on the heavy metal levels in Ophelia bicornis (Savigny, 1820) in the Black Sea (2021)

    Description: In the current work, the levels of mercury, cadmium, lead, copper and zinc have been determined in Ophelia bicornis and in sediments collected seasonally from the Sinop coast of the southern Black Sea in 2015. Hg and Pb levels were usually greater in sediment than those in worms. Cd, Cu and Zn levels, however, were higher in the worm samples. Zn had the maximum concentration factor average and Pb displayed the minimum concentration factor value. It may be turned out that O. bicornis has capability to accumulate the heavy metals from the marine ecosystem and it will be used as a bio-monitor species for Cd, Cu and Zn in the Black Sea.

    Description: The levels of Hg, Cd, Pb, Cu, Zn and Fe in the whole soft tissues of thelimpet, Patella caerulea, from the Black Sea coast has been determined by InductivelyCoupled Plasma – Mass Spectrometer (ICP-MS). Mercury was not detected in P.caerulea, and iron is seen to be the most abundant of the metals examined. The resultsshowed that the monthly mean levels of all other metal levels in July were lower thanthose in May and June. The heavy metal levels in the limpet P. caerulea are low andacceptable levels. The present study confirmed that the limpet P. caerulea is good bioindicatorfor monitoring of metal pollution in the coastal area.

    A primary study on the bioaccumulation of ‎metals in Stereoderma kirschbergi (Heller, ‎‎1868) ‎from Sinop coasts of the southern Black Sea‎. (2021)
    Details
    Publication Date: 2021-05-19
    Description: The amounts of toxic metals (Pb, Hg and Cd) in tissues of Stereoderma kirschbergi in the ‎Sinop coasts of the south of the Black Sea were measured for the first time. Toxic metal ‎analyses were made by the Inductively Coupled Plasma - Mass Spectrometer. The ‎general tendency in all metal concentrations in both sediment and sea cucumber samples ‎were Pb〉Hg〉Cd. The results demonstrated that the toxic metal concentrations in ‎sediments were higher than organisms. Pb values in the sediment and sea cucumber were ‎higher than Hg and Cd. The bio-sediment accumulation factors for Cd, Hg and Pb were ‎lower than 1. S. kirschbergi is considered as a de-concentrator.‎

    A review of aquatic toxicology investigations in Turkish waters. (2023)
    Details
    Publication Date: 2023-12-15
    Description: Aquatic toxicity studies have been conducted for many years, and their importance has been understood for some time. The need for aquatic toxicity studies arises from the widespread use of chemicals in many different industries, such as agriculture, manufacturing, and energy production. These chemicals can enter aquatic environments through various means, including runoff from fields, discharges from factories, and spills or leaks from storage tanks or pipelines. Once in the aquatic environment, these chemicals can have harmful effects on aquatic life, including fish, crustaceans, molluscs, and algae. By conducting aquatic toxicity studies, researchers can gain a better understanding of the potential harmful effects of chemicals on aquatic life and ecosystems and can inform decisions about their use and regulation to protect the environment. This review summarizes the available aquatic toxicity studies in Turkish waters.

    Heavy metals risk assessment for consumption of wild Mediterranean mussels Mytilus galloprovincialis Lamarck, 1819 along Samsun Coasts of the Black Sea (2024)
    Details
    Publication Date: 2024-01-11
    Description: The present study aimed to determine the concentration of metals in the soft tissue of wild mussels in coastal of Samsun and to assess human consumption. Using inductively coupled plasma mass spectrometry, the quantities of cadmium, mercury, lead, copper, iron, and zinc in Mytilus galloprovincialis were measured. The heavy metals found in Mediterranean mussels are arranged in the following ascending order: Cd 〈 Hg 〈 Pb 〈 Cu 〈 Fe 〈 Zn. Concentrations of toxic metals were safe according to European Commission guidelines and the Ministry of Agriculture, Forestry and Fisheries. According to the estimated daily intake (EDI), eating Mediterranean mussels poses no risks. The target hazard quotients (THQs) in metals are also found 〈1, which implies no threat to consumers. In conclusion, the current study confirmed that the concentration of heavy metals in the Mediterranean mussels is safe for people intake in terms of their toxicity.
