Determination of heavy metals in selected black sea fish species

Accumulation of Cadmium and Lead in Commercially Important Fish Species in the Gulf of Gemli̇k, Marmara Sea, Turkey

“…Aquatic pollution studies attract the attention of many investigators (Balkıs et al 2013;Chahid et al 2014;Makedonski et al 2015;Araujo and Cedeno-Macias 2016). Determination of trace metal accumulation in various fish species from seas, lakes, rivers, and reservoirs have largely been conducted in food safety studies.…”

Arsenic intoxication: general aspects and chelating agents

“…Near the Swallow's Nest, where 24 barrels were flooded, some of the containers were destroyed; and due to their As content, the water exceeded the norm by more than 100 times (Samar 2013). Conversely, in a study devoted to the determination of toxic metals, including As, in selected Black Sea fish species in the Bulgarian region (sampling season 2010) gave encouraging results within acceptable limits for human consumption and decreased total metal concentration according to the analysis performed in the period 2004(Makedonski et al 2017.…”

Electroactive properties of a new azulene thioxo-imidazolidin-4-one ligand for modified electrodes

“…Classical techniques used for the determination of heavy metal ions are: spectrometry (graphite furnace atomic absorption spectroscopy, flame atomic absorption spectroscopy, inductively coupled plasma optical emission spectrometry), and chromatography (gas chromatography, high performance liquid chromatography). These methods are precise, but they require complex equipment (expensive), and well-trained staff [9][10][11][12][13] to maintain and use them. Stripping analysis using chemically modified electrodes (CMEs) is an alternative to these classical methods, offering the following advantages: higher selectivity due to the specific interactions between the metal ions and complexing matrix, limited chemical interferences, and capability to sense metals as Hg or Ag [5,14].…”
