The analysis of trace metals and their distribution in marine sediments is a very importantstep toward understanding geochemical and environmental processes and their possible changes due to anthropogenic activities. The present work reports results concerning the distribution of some major (Al), (Fe), and trace (Be, Cd, Cr, Mn, Ni, Pb, Sn, Zn) elements in Antarctic marine sediments. Chemical data...
An improved method for the determination of the systemic fungicide fosetyl-aluminum (aluminum tris(ethyl phosphonate)), in commercial formulations, via the quantitative determination of the phosphonate anion is described. The method employs HPIC using eluent suppression and conductivity detection. Two different kinds of chromatographic columns were utilized in the study, together with several eluents...
