Abstract

Heavy metal concentrations in aquatic ecosystems are usually monitored by measuring their concentrations in water, sediments and biota, which generally exist in low levels in water and attain considerable concentration in sediments and biota. Heavy metals such as copper, iron and nickel are essential metals since they are playing an important role in biological systems, whereas cadmium and lead are non-essential metals, as they are toxic, even in trace amounts (W. de Vries et al., 2007). The purpose of this paper is to investigate the heavy metals (Mn, Cd, Ni, Cr, Zn, Pb and Cu) contamination levels of sediment and fish from Cernavoda-Topalu area. The total concentrations were analyzed according to the microwave aqua regia digestion method, using Mars 5 Microwave System. The quality control of the digestion procedure was tested using the NCS ZC 73006 Certified Reference Material (CRM). Measurements of the CRM showed that the recovery after destruction in the digestion oven was 95% and 110%. Thus, for the method, a very good recovery was considered.
