Metal speciation in natural waters is of increasing interest and importance because toxicity, bioavailability, environmental mobility, biogeochemical behavior, and potential risk in general are strongly dependent on the chemical species of metals.etal speciation in natural waters is of increasing interest and importance because toxicity, bioavailability, environmental mobility, biogeochemical behavior, and potential risk in general are strongly dependent on the chemical species of metals.
â¢ Speciation analysis is the analytical activity of identifying and/or measuring. the quantities of one or more individual chemical species in a sample. â The chemical species are specific forms of an element defined as to isotopic. composition, electronic or oxidation state, and/or complex or molecular structure. â¢ Different forms of an element can have totally different properties. â Essential for predicting and modeling fate, risk, and effects, Critical for toxicology, bioavailability, and bioaccumulation. â In fact, speciation of an element can even impact total elemental analysis. â¢ Speciation Analysis Can Answer Tough Questions
