“…We did not monitor systematically the tetraalkyllead species in the same samples; some of them, including unfiltered and freshly collected rain after showers, were preextracted with hexane, and no TAL compounds were detected, with a detection limit of 20 ng-L"1. Moreover, none of the numerous natural water samples investigated so far by several groups was found to contain tetraalkyllead (9)(10)(11)(12), with claimed detection limits for hexane-extractable lead as low as 1 ng-L"1, except for a recent report that demonstrates TAL contents in rain of up to 90 ng-L"1 (13).…”

“…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.

“…Organolead compounds are ubiquitous in the environment, having been detected in air (1-3), street dust (4), rainwater (5), cod, lobster, and mackerel (6), freshwater fish (7,8), pigeons (9), and human brains (4-84% of the total lead) (10). Investigations of the environmental fate of tetralkylleads (used as gasoline antiknock additives) have been hampered by the lack of suitable methodology for determining ionic alkyllead species (R3Pb+ and R,Pb2+; R = Me, Et) in biological tissue.…”
