Mercury in canned fish from local markets in the Czech Republic

Abstract

The aim of this survey was to compare total mercury (THg) in canned fish in terms of species and fishing area. A number of 110 samples of canned fish, which were divided by fish species and fishing area, were analysed. The highest THg content in muscle tissue was found in the escolar. In other fish species, the highest level was detected in tuna. Mercury content in tuna differed significantly from mackerel, sardine, and sprat. Mercury content in herring differed significantly from sprat. The order of the fish according to their THg content corresponds to their status in the aquatic food chain. A significant difference was also found between fish caught from the closed Mediterranean and Black Sea and fish caught in the open oceans. In terms of THg content, the results of this study indicate good quality of various species of canned fish caught in worldwide locations.

Canned sardines commercialized in Brazil: Packaging and inorganic contaminants evaluation

“…Concerning with public health, several studies have been carried out with canned foods in order to determine the content of trace elementsespecially with those whose essential body function is not known. Inorganic contaminants were studied in canned fish (tuna and sardines) in Austria (Suppin, Zahlbruckner, Krapfenbauer-Cermak, & Hassan-Hauser, 2005); in Brazil (De Paiva, Milani, & Morgano, 2017;Lazarini, Milani, & Morgano, 2019;Medeiros et al, 2012); in Spain (Olmedo et al, 2013); in the United States (Shiber, 2011); Ghana (Okyere, Voegborlo, & Agorku, 2015); in Italy (Storelli, Barone, Cuttone, Giungato, & Garofalo, 2010); in Iran (Hosseini et al, 2013); Libya (Abolghait & Garbaj, 2015); in Niger (Babalola et al, 2014), in Portugal (Afonso et al, 2015); in Czech Republic (Kral, Blahova, Sedlackova, Kalina, & Svobodova, 2017); in Serbia (Novakov et al, 2017) and in Turkey (Yabanli, 2013).…”

Mercury intake via consumption of imported Atlantic mackerel (Scomber scombrus) in Istanbul

“…Łuczyńska and Krupowski (2001) stated that the contents of Hg in Scomb-er scombrus bought from supermarkets of Olsztyn, Poland ranged between 0.039-0.068 mg/kg (mean 0.052 mg/kg). In addition, Kral et al (2017) and Mol (2011) found that average concentrations of total mercury (mg/kg) lower than the legal limit (1.00 mg/kg) for canned mackerel. The value of Hg in frozen Atlantic mackerel purchased from the Jagalchi fish market of Korea was found to be 0.08 mg/kg (Bae et al, 2011).…”

“…However, as much as the amount of Hg in fish, the amount of fish consumed by human is also important in terms of potential health risk. The risk assessment based on the target hazard coefficient (THQ) indicates the potential health risks from dietary metal intake (Burger, 2009;Kral et al, 2017).…”

Exposure assessment in the Serbian population and occurrence of histamine and heavy metals in fish and seafood

“…Among fish, the highest level of mercury (0.58 mg kg −1 ) was measured in tuna. The average levels in sample groups were higher than levels reported by other authors in fish from markets in Serbia (Popovic et al ., 2018; Novakov et al ., 2017), Croatia (Bilandžić et al ., 2011;Bilandžić et al ., 2018), in sardines from markets in Greece (Sofoulaki et al ., 2018), in canned tuna from Italy (Storelli et al ., 2010), in fish from the Ionian Sea (Copat et al ., 2014), Spain (Rodríguez‐Hernández et al ., 2016), in fish from the Black Sea (Makedonski et al ., 2017), in canned fish in Czech Republic (Kral et al ., 2017) and in fish from Turkey (Mol 2011), Iran (Andayesh et al ., 2014), Morocco (Adil et al ., 2014), Ghana (Okyere et al ., 2015), USA (Shiber 2010) and Brazil (de Paiva et al ., 2017). Nevertheless, the reported average mercury levels in fresh tuna from Italy (Storelli et al ., 2010), in tuna imported into Italy (Galimberti et al ., 2016) and in canned tuna from Cartagena, Colombia (Alcala‐Orozco et al ., 2017) were higher than this study.…”
