“…The other species of ionic lead were generally present at <1 ng Pb B~l levels. R4Pb compounds were not identifiable in surface waters from Ontario, Canada, using GC/AAS (10,11,12,16). R3Pb + and R 2 Pb + species were, however, found in river water samples collected near tetraalkyllead manufacturing plants in the same area (16).…”

Gas chromatography/atomic absorption spectrometry was used to determine specific alkyllead compounds in surface and potable water samples. For the first time ionic alkyllead species were identified in potable waters at very low levels with concentrations up to 4 ng Pb 1 -1 . No tetraalkyllead compounds were found in any of the samples analysed and laboratory studies demonstrated that these species decompose rapidly in aqueous samples to trialkyl lead, the most common form of organic lead in environmental samples.

“…Chelation/extraction can also be used to recover lead from aqueous matrices (APHA 1998). GC/AAS has been used to determine organic lead, present as various alkyl lead species, in water (Chakraborti et al 1984;Chau et al 1979Chau et al , 1980. Sample preparation for organic lead analysis was either by organic solvent extraction (Chakraborti et al 1984;Chau et al 1979) or purge-and-trap (Chau et al 1980).…”

“…The primary detection methods are ICP/AES, AAS, or GFAAS (GFAAS being more sensitive, but also more susceptible to interference). When quantification of organic lead is desired, GC is employed to separate the alkyl lead species (Chau et al 1979(Chau et al , 1980. Precision and accuracy are acceptable for these atomic absorption-based methods (Beyer and Cromartie 1987;Bloom and Crecelius 1987;Chau et al 1979;EPA 1986c;Krueger and Duguay 1989;Que Hee et al 1985b).…”

“…There have been a number of observations of methyl tin derivatives in natural waters and biota [2][3][4][5] and these probably do not arise solely from industrial or laboratory use of the various methyltin compounds. There have also been reports of methyl lead compounds in the environment which may not have arisen from leaded gasoline [6][7][8][9]. In addition several laboratory demonstrations have suggested that inorganic tin and lead compounds may be incubated in samples of natural sediments or micro-organisns to produce small yields of methyl metal products [10][11][12].…”
