摘要:

Organic mercury compounds in lake sediments were separated into dialkyl- and monoalkylmercury fractions by steam distillation and subsequently quantified by flameless atomic absorption. The method recovered nearly all CH3HgCH3and CH3HgCl added to diverse sediments. Parameters influencing the efficacy of the procedure, i.e., Hg concentration, sample size and distillation time, were evaluated.
