Determination of inorganic trace elements in edible marine fish from Rio de Janeiro State, Brazil

Abstract

a b s t r a c tFish and seafood may represent risk for human health since they can accumulate contaminants from aquatic environment and magnify them up the food chain. The purpose of this study was to analyze and evaluate the levels of aluminum, zinc, iron, manganese, cobalt, copper, arsenics, selenium, cadmium, barium, lead and bismuth in 11 fish species (Salmo salar, Sardinella brasiliensis, Pomatomus saltatrix, Micropogonias furnieri, Cynoscion leiarchus, Caranx crysos, Priacanthus arenatus, Mugil cephalus, Genypterus brasiliensis, Lopholatilus villarii and Pseudopercis numida) captured at Rio de Janeiro State Coast, Brazil. Concentration ranges (mg kg À1 of wet weight) of the selected elements were compared with those reported in other studies. In some cases, comparison of certain elements in the same fish species was difficult due to the lack of data. Aluminum concentration was significantly high in all samples and only M. cephalus, C. leiarchus e C. crysos presented arsenic concentrations below 1 mg kg À1 , limit recommended by Brazilian legislation.

Trace element concentrations in the apex predator swordfish (Xiphias gladius) from a Mediterranean fishery and risk assessment for consumers

“…The world consumption of fish has increased simultaneously with the growing concern of their nutritional and therapeutic benefits (El-Moselhy et al, 2014). In addition to its important source of protein, fish typically have rich contents of essential minerals, vitamins and unsaturated fatty acids (Medeiros et al, 2012). However, the content of toxic TE in fish can counteract their beneficial effects (Castro-González and Méndez-Armenta, 2008).…”

Assessment of human health hazard due to metal uptake via fish consumption from coastal area of Tanzania

“…It is documented that fish is a good source of essential minerals, protein, unsaturated fatty acids and vitamins. The consumption of fish as well as its products has increased mainly due to their health benefits such as preventing cardiovascular and other disease (Medeiros et al, 2012).…”

“…However, factors such as time, gender, catching place, age and habitat may modify chemical constituents and pollutant burden can diverge among diverse species and even among individuals of the same species (Medeiros et al, 2012).…”

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

“…Therefore, many studies have been conducted on the accumulation of trace elements in fish and other organisms in aqueous environments. 3 Fish incorporates trace elements by ingestion of suspended particulate matter in the water column and of food, by ion exchange of dissolved elements across lipophilic membranes (e.g., the gills) and by adsorption of elements on tissue and membrane surfaces. Since that the element distribution in different tissues depends on the way of exposure, i.e., dietary and/or aqueous exposure, the measurement of this distribution can serve as a pollution indicator.…”

“…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.…”
