Heavy metals in environment

An evaluation of different state of Hg, Cr and heavy metals pollution in seawater and sediments of Durres Bays Adriatic Sea is given. Some geological considerations and normalisation procedures are used to explain the anthropogenic-input fraction of heavy metals in this bay. It is clearly demonstrated that some industrial activities, such as mining, harbouring and chemical plant activity, notably affect Cr 6+ and heavy metals concentration in sediments. It is demonstrated that the most important pollutant of Durres Bay is chromium, whose concentration in sediments goes to 550 mg/kg and the highest concentration of Cr 6+ was found to be 16.6 μg/L in seawater near the ex-chemical factory.
