Determination of 20 trace elements in fish and other seafood from the French market

Essential mineral content of common fish species in Chanoga, Okavango Delta, Botswana

“…The differences could be due to differences in environmental conditions, fish diet, water quality and species studied. Study by Guerin et al (2011) carried out with fish from a French market reported much lower concentration levels of Fe (0.13 -1.9 mg/100 g). The literature reviewed for this work show a high variation in the concentration of iron in fish from country to country.…”

Assessment of Trace Elements in Tissues of Fish Species: Multivariate Study and Safety Evaluation

“…Comparison with the mean Li values in previous reports suggests that the results of the present study are generally lower than those reported in other studies. 32 Guérin et al 32 measured a range of Li concentrations (mg kg -1 wet weight) in liver and gill tissues: liver (0.15 to 0.57), gill (0.22 to 0.30). 2 In the present study, the measured concentrations were (mg kg Cadmium is a non-essential element found in foods and natural waters with potential toxicity to fishes even at low levels.…”

The Cd concentrations in the fish tissues analyzed in this study were 0.159-1.366 mg kg -1 in stomach, 0.093-0.525 mg kg -1 in gills, 0.401-0.961 mg kg -1 in liver, and 0.047-0.081 mg kg -1 in kidney.…”

“…1 However, fish and seafood may pose risks to human health because they may contain toxic substances, such as trace elements and persistent organic pollutants. 2 Fish serves as advantageous bioindicators because (i) they have long lifespans; (ii) they develop and live in water allowing continuous monitoring of pollutants and simultaneous spatial integration of pollutant data; and (iii) they are relatively easy to sample. Therefore, many studies have been conducted on the accumulation of trace elements in fish and other organisms in aqueous environments.…”

“…Muscle is commonly analyzed to determine contaminant concentrations and to assess health risks because it is the main fish tissue consumed by humans. [2][3][4][5][6] However, organs, actively involved Vol. 27, No.…”
