Determination of ionic alkyllead compounds in natural waters by differential-pulse anodic stripping voltammetry

TL;DR: In this paper, a method for the determination of ionic alkyllead compounds in natural waters is described, which is based on the extraction of organolead compounds in the form of diethyldithiocarbamate complexes into hexane, their re-extraction with dilute nitric acid (pH 1.5), purification of the aqueous acidic solution from interfering co-extracted DICs, and determination of alkylead species by differential-pulse anodic stripping voltammetry.

Oxidation processes at mercury electrodes for tetraphenyllead and related compounds in dichloromethane

TL;DR: In this article, two oxidation waves are observed at mercury electrodes for tetraphenyllead in dichloromethane, and the mechanisms of the oxidation processes have been investigated by dc and differential pulse polarography.

Examination of interferences in the stripping voltammetric determination of trimethyllead in seawater by polarography and mercury-199 and lead-207 nuclear magnetic resonance spectrometry

TL;DR: In this article, it was shown that trimethyllead ions react with trimethyl lead cations in seawater and other aqueous media according to the equation Hg/sup 2 +/ + ((CH/sub 3/)/sub 3 /Pb)/sup +/..-->..CH/ sub 3/Hg/Sup +/+ Pb/sup 1 +/2 + 2CH/Sub 3/

Reversible oxidation processes in dichloromethane for triethyl-, diethyl-, trimethyl-, and dimethyllead compounds at mercury electrodes

TL;DR: In this paper, the trialkyl derivatives of R3PbX give rise to a reversible oxidation process involving transfer of one electron, exchange of alkyl groups and X− and formation of a mercury-lead complex.

Determination of the chemical forms of dissolved cadmium, lead and copper in seawater

TL;DR: In this paper, the chemical forms of Cd, Pb and Cu in seawater have been examined using a novel scheme which permits the quantification of up to seven different species of one metal.

Methylation of lead in the environment.

TL;DR: The methylation of mercury and arsenic by microorganisms in the environment has been documented and well summarised, but nothing is known about the existence of organic forms of lead in the environments as a result of biotransformation.
Journal ArticleDOI

Toxicity, mutagenicity and teratogenicity of lead

TL;DR: The data on man are controversial because lead is almost never the only potentially mutagenic agent to which people are exposed in an industrial environment, and the efficiency of lead in causing such aberrations appears low compared with that of other mutagenics so that genetic effects of lead do not appear of primary concern for human health.

Determination of trace metals in marine samples by anodic stripping voltammetry

TL;DR: Anodic stripping voltammetry with a polished glassy carbon electrode mercury-plated in situ was applied to the determination of trace metals in seawater, seaweeds and marine organisms as discussed by the authors.
