To date, most studies describing the effect of plant secondary metabolites on herbivore digestion in marine systems have focused upon the macromolecular-complexing activity of algal phlorotan-nins. While these compounds have demonstrated negative effects on marine herbivore food preference and digestion efficiency in some circumstances, it is clear that they can no longer be... 

For the multispecies determination of a maximum of four species like inorganic Hg2+, Me-Hg, ethyl-Hg, and phenyl-Hg an automatic system was devised based on the on-line coupling of HPLC with CV-AFS via a postcolumn MW digestion. The digestion medium was K2S208 in HC1. Parameters influencing on-line digestion efficiency and the separation effects were optimized, which allowed for the separation of the four Hg species within 13 min. The absolute LoDs were 0.3 ng for Hg2+, 0.2 ng for Me-Hg, 0.17 ng for ethyl-Hg, and 0.14 ng for phenyl-Hg+ [63].

For the determination of antimony, the digestion efficiency of particulate matter, collected on Whatman 41 cellulose filters, was evaluated by means of radiotracer experiments [6], A quantitative recovery was obtained using 8 ml sulfuric acid and 4 ml hydrogen peroxide, when applied to a quarter fraction of the filter. For the dissolution of residual silicates 0.5 to 4 ml of hydrofluoric acid were added, which were later on evaporated. After digestion the solution was filtered if needed and diluted appropriately. 

In this work the Eurachem guide [1] was used for the estimation of uncertainties involved in the determination by electrothermic atomic absorption spectrometry (EAAS) of manganese in digested lettuce leaves. The total uncertainty estimation was calculated assuming a 100% digestion efficiency with negligible uncertainty. The experimental precision was compared with an estimated one for the purpose of validation of the proposed method of evaluation. After this validation the uncertainty estimation was used in an accuracy test and in routine analysis with the support of a spreadsheet programme.
