Trajectories of cognitive decline over 10 years in a Brazilian elderly populati...
Castro-Costa,Erico; Dewey,Michael E.; Uchôa,Elizabeth; Firmo,Josélia O. A.; Lima-Costa,Maria Fernanda; Stewart,RobertFew population-based studies have examined long term cognitive trajectory, and these studies were conducted in high income countries.

Analysis of Mercury-Rich plants and mine tailings using the Hydride-Generation ...
Moreno,Fábio Netto; Anderson,Christopher; Stewart,Robert; Robinson,BrettA hydride-generation atomic absorption spectroscopy (AAS) method was developed for the analysis of total Hg in liquid matrices of mercury-rich plants and mine tailings samples. The detection limit for this method was as low as 11.4 ng/mL. The reproducibility of the mercury signals (in terms of relative standard deviation) was 4.6%. Accuracy of the method was verified by analyses of deionised water samples spike...
