The presence of the highly toxic antifouling agent tributyltin (TBT) and its degradation products was determined in four species of mussels collected from 34 locations in fresh water in Ontario and in sea water on Canada's west and east coasts. The purpose of the study was to establish baseline information in order to assess TBT trends in mussels after the 1989 Canadian regulation of antifouling uses of TBT. In fresh water, concentrations of TBT were much higher in zebra mussels (Dreissena polymorpha) than in Elliptio complanata or Lampsilis radiata radiata. High concentrations of TBT were also found in Mytilus edulus in sea water. Residues of TBT in all species were similar to those that have been determined in other parts of the world before and after the regulation of antifouling uses of TBT in various countries. Analyses for degradation products indicated that zebra mussels metabolize TBT at about the same rate as L. radiata radiata and M. edulis, but more slowly than E. complanata. © 1997 John Wiley & Sons, Ltd.

Atomic absorption spectrometry (AAS) is one of the most often used techniques for the quantitative determination of elements in environmental materials at trace and ultratrace levels. AAS is an optical atomic spectrometric technique based on the measurement of the specific absorption originating from free nonionized atoms in the gas phase. To transfer the analyte to free atoms, different types of atomizer are in use, the flame and the graphite furnace types being the most often used. Typical detection limits of flame atomic absorption spectrometry (FAAS) are of the order of 1–100 µg L −1 , making it a perfect tool for the determination of minor and trace elements, at least for contaminated samples. Graphite furnace atomic absorption spectrometry (GFAAS), offering detection limits which are about a factor of 20–200 lower than for FAAS, is the standard method for many trace elements, especially for background values, and for unpolluted samples, such as fresh water and biological materials. AAS in its conventional configuration is a single‐element technique, which has to be used in a sequential mode when more than one element has to be determined. However, there are commercial instruments available that can be used for the determination of 6–8 elements simultaneously.
Atomic absorption spectrometry (AAS) is a well‐established technique for the quantitative determination of elements in environmental materials at trace and ultratrace levels. AAS is an optical atomic spectrometric technique based on the measurement of the specific absorption originated from the free, unionized atoms in the gas phase. For transferring the analyte to free atoms, different types of atomizers are in use, out of which the flame and the graphite furnace are the most often used atomizers. Typical detection limits of flame AAS (FAAS) are of the order of 1–100 μg L −1 , making it a perfect tool for the determination of minor and trace elements, at least for contaminated samples.

However, there are commercial instruments available, that can be used for the determination of six to eight elements simultaneously. While most manufacturers provide instruments working with line sources, one manufacturer has commercialized high‐resolution instruments working with continuum sources (HRCS‐AAS).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
