Metal Speciation in the Environment is a multidiscipliary treatment of the occurrence, mobility and detection of metal compounds within different environments as well as their interaction with life. Special emphasis is given to the complexation of metals, to the state of the art of trace analytical methodology available for metal speciation (including atomic absorption spectrometry, plasma emission and mass spectrometry, neutron activation analysis, electrochemical methods, chemical sen- soring, a.o.), and environmental chemistry of elements such as the actinides and heavy metals (e.g. chromium, arsenic, tin, and copper).
