Trace metals in the marine bivalve Macoma balthica in the Westerschelde estuary (The Netherlands) Part 1 : Analysis of total copper, cadmium, zinc and iron concentrations - locational and seasonal variations
In the aquatic environment, the uptake of trace metals by living organisms depends strongly on their total concentration and their chemical forms (external speciation). The levels of concentration and the existence of different chemical species will determine the bioavailability to organisms and, therefore, the essential role or eventual toxicity of a metal. After uptake of a metal the accumulation pathways can alter its bioavailability as a consequence of the different medium leading to new chemical species. This paper details the procedure used for the total concentration determination of four trace metals, copper, cadmium, zinc and iron, in the marine bivalve Macoma balthica. Measurements were made in the Weterschelde estuary every two months over the period of a year using atomic absorption (AAS) and emission (ICP) spectrometry, and resulting conclusions are presented.
