“…The liver seems to be more sensitive to environmental conditions, but his sensitivity depends on the nature and the type of the metals. Zn also plays an important role in human health and ecosystems because it constitutes an essential element (in the state of <0.01%) for the proper functioning of the metabolism of living organisms [24]. Indeed, it acts as a cofactor in metallo-enzymes by catalyzing the enzymatic reaction or by providing a structure three-dimensional active enzyme.…”

The content of four heavy metals (zinc, iron, chromium and copper) in muscles, liver and gonads has been studied for the five most consumed fish species (Cephalopholus taeniops, Scomber japonicus, Lagocephalus laevigatus, Pagellus bellottii and Pagrus caeruleostictus) in the Soumbedioune region. The samples were digested by acid digestion. The metal contents were quantified using a PF-11 type photometer. The results obtained show that metals such as zinc, iron and chromium are significantly higher (p <0.05) in the muscles of the four species than in the liver and gonads. However, the levels of heavy metals in the muscles, liver, and gonads of the five species are above the acceptable limit recommended by the FAO and WHO, with the exception of the copper levels in the gonads of the species Pagellus bellottii.

“…Le Zn joue aussi un rôle important dans la santé humaine et la santé des écosystèmes car il constitue un élément essentiel (à l'état de traces <0.01%) pour le bon fonctionnement du métabolisme des organismes vivants (Tahiri, 2005). En effet, il agit à titre de cofacteur dans les métallo-enzymes en catalysant la réaction enzymatique ou en assurant une structure tridimensionnelle active de l'enzyme.…”

Pollution of metal origin constitutes one of the major risks in the world today. The metal elements can be very dangerous to human health when they are present in the environment at high concentrations. Thus, the evaluation of the metal contamination in marine organisms, especially fish, makes it possible to predict a possible contamination of humans. This paper focuses on studying the metal contamination of the beach of Soumbédioune, located at the western frontage of the area of Dakar. This site, where fish products are offloaded, is the home to Canal IV (West Canal), which drains urban wastewater. In this study, we evaluated the concentrations of the metal elements (Fe, Zn 2+ , Cr 6+) in the bodies of Brama brama using a visible spectrophotometry UV. The results obtained show a strong concentration of chromium plates of 24,5 µg/g which is obtained at the level of the liver. Zinc presents a content of 16,7 µg/g at the level of the skin, but it was not detected at the level of the liver and the flesh. The maximum iron content was recorded at the level of the liver with a value of 77,5 µg/g. However, the values obtained were definitely higher than the standards established by FAO and the CEE.

“…Accordingly, metal contamination of aquatic ecosystems has received the attention of researches for many years because it is one of the most harmful pollutants in aquatic environments. Its harmful effects can generate critical, sometimes dangerous, situations affecting the ecological balance of aquatic ecosystems (Tahiri et al, 2005). Unlike many organic pollutants, heavy metals are not typically eliminated by biological processes, enhancing their cumulative effects in different parts of natural ecosystems, including water, sediments, fauna and flora (Belajal & Hmidi, 2020).…”

Assessment of heavy metal and organic pollution of a salmonid ecosystem: Case of the Oued Guigou River, Middle Atlas (Morocco)

The present study focused on evaluating the quality of the Oued Guigou River located in Middle Atlas (Morocco) by studying relevant physicochemical and metallic parameters. Samples for determining the organic matter and trace metal elements trapped in water samples were collected at upstream of Oued Guigou between December 2020 and April 2021. The samples were analysed for physicochemical quality, while the trace metal elements (lead, zinc, copper, chromium, iron, nickel, calcium and magnesium) were determined using ICP‐AES analysis. The results indicated significant organic pollution, as well as standard deviation and average changes in the values of the studied metals, most likely attributable to domestic effluents. The metal content in particular exhibited high values exceeding the recommended Moroccan standard limits, suggesting domestic and agricultural pollution is a potential threat to both the receiving rivers and their associated lakes and reservoirs.
