Geochemical Characteristics of Heavy Metals Concentration in Sediments of Quiberon Bay Waters, South Brittany, France
نویسندگان
چکیده
Cr, Co, Cu, Zn, Cd and Pb in the bottom sediments from 93 sites at Quiberon bay were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICPMS) after acid extraction. The ranges of the concentration in the sediments are as follows: 27.3 μg/g (Cr), 11.6 μg/g (Co), 13.8 μg/g (Cu), 42.0 μg/g (Zn), 0.08 μg/g (Cd) and 17.8 μg/g (Pb). Potential contamination of the bay was assessed by Igeo and pollution load index whether the concentration observed represent background or contaminated levels. Based on the results, it can be concluded that the bay is unpolluted for the studied metals.

Desalination plants are potentially capable of having impacts on coastal marine environments due to the production of wastewater with high concentrations of salts (brine discharge) and some heavy metals. The aim of this study was to examine the concentration of accumulated metals (Ni, Cu, Cd, Fe, Zn, Pb) in the sediments near the brine discharge point in the Chabahar Bay. Twenty one sediment sa...

Heavy metals and some organic substances which are drained into the aquatic environments and cannot be decomposed or eliminated will sink into sediments or find their way into different levels of food chain. Bioaccumulation is the process of continuous deposition and aggregation of these substances into the body tissue of living organisms. Mollusks are remarkably appropriate to be used as bio-i...
