Occurrence and speciation of organometallic compounds in freshwater systems / Y.K. Chau. : En13-5/85-64E-PDF

"This is a review paper on the environmental occurrence of organometallic compounds and the recent developents in their speciation in water, sediment and biological samples. The sources of organometallic compounds are mainly from anthropogenic inputs and from biotic and abiotic methylation processes.The most sophisticated analytical methods for organometallic speciation are combination systems consisting of a separation technique coupled with an element-specific detector. The best systems to date are gas chromatography (GC) or liquid chromatography (LC) coupled with an atomic spectrometric detector in the absorption or emission mode with sensitivity in the sub-nanogram level.Techniques for quantitative extraction of ionic organometals, methods of derivatization and digestion of biological samples without destruction of the original chemical form are discussed. With these techniques, the occurrence of molecular and ionic alkyllead compounds (R= Me, Et) has been found for the first time in water, sediment and fish in areas of lead pollution"--Exec. summary.
