Levels of Heavy Metals in Canned Bonito, Sardines, and Mackerel Produced in Turkey

Abstract

Concentrations of selected metals were determined using ICP-MS in canned bonito, sardines and mackerel commercialized in Turkey. Thirty samples and two different brands were sampled for each fish species. The minimum and maximum concentrations of trace metals in canned bonito, sardines and mackerel were found as 0.000-34.742, 0.000-89.015, 0.000-28.725 mg/kg for iron, 2.388-26.620, 10.930-41.340, 4.778-29.270 mg/kg for zinc, 0.331-1.548, 0.599-2.242, 0.336-2.884 mg/kg for copper, 0.000-0.065, 0.000-0.113, 0.000-0.115 mg/kg for cadmium, 0.000-0.190, 0.000-0.158, 0.000-0.385 mg/kg for tin, 0.000-0.111, 0.000-0.223, 0.000-0.208 mg/kg for mercury and 0.000-3.046, 0.000-2.875, 0.000-3.529 mg/kg for lead, respectively. These levels are similar those found in other studies. Although the samples have concentrations within permissible limits for Zn, Cu, Sn and Hg, some of them contained Fe, Cd and Pb above these limits. Periodical controls of metals in canned fish are essential both to protect human health and to provide data on this subject.

Toxicity of mixtures of λ-cyhalothrin, imidacloprid and cadmium on the earthworm Eisenia fetida by combination index (CI)-isobologram method

“…Cadmium is a non-biodegradable metal; it possesses a potential to accumulate in living organisms and can be incorporated into the food chain. Soil contamination with Cd is widespread due to its intensive use, which is recognized to be the most hazardous pollutants to various ecosystems and human health (Mol, 2011). These chemicals were selected due to their large-scale production, high usage frequency, and their content in the terrestrial environment.…”

“…Copper is an essential element for good health and seafood is known as a good source of dietary copper, but it is very toxic when consumed excessively (Mol, 2011), and for that reason, a maximum limit intake of Cu was set at 30 mg/day by WHO (WHO, 1996). Therefore, a high intake of Cu has been recognized to cause adverse health problems such as kidney and liver damage for human (Hussein, & Khaled, 2014;Stancheva, Makedonski & Peycheva, 2014).…”

“…Iron deficiency causes anemia, reducing cognitive function and also physical work capacity. Whereas, high intake of this element may be the cause of organ failure (Mol, 2011;Hussein, & Khaled, 2014;Stancheva et al, 2014;Wheal, DeCourcy-Ireland, Bogard, Thilsted, & Stangoulis, 2016). Vertebrates (mammals, birds and fish) meat is known good sources of Fe for their high total Fe concentration, as well as presence of haem Fe.…”

The Analysis of Pb and Cu levels in Canned fish and Sauces for the Storage Time

“…Hasil beberapa penelitian menunjukkan ikan kemasan kaleng baik produksi Indonesia maupun luar negeri telah tercemar logam berat. Penelitian tersebut diantaranya; terdapat cemaran timbal (Pb) dan tembaga (Cu) pada sampel ikan kaleng di Indonesia (Tehebijuluw et al, 2003), cemaran Pb dan Cd ditemukan pada ikan kemasan kaleng (Samosir, 2011), ditemukan Fe, Zn, Cu, Sn, serta Mn pada ikan kaleng di Brazil (Tarley, 2001), serta logam Fe, Zn Cu, Sn dan Mn pada ikan kemasan kaleng di Turki (Mol, 2011). Konsentrasi logam yang ditemukan sebagian melebihi ambang batas.…”
