1. Impact of Fungicide Residues on Polymerase Chain Reaction and on Yeast Metabolism
ABSTRACT The indiscriminate use of pesticides on grape crops is harmful for consumers´ healthin “in natura” consumption and in the ingestion of wine and grape juice. During winemaking, a rapid and efficient fermentation stage is critical to avoid proliferation of contaminating microorganisms and to guarantee the product´s quality. Polymerase chain reac

2. Elementos-traço e sódio em suco de uva: aspectos nutricionais e toxicológicos
Eight trace elements were determined in 20 Brazilian brands of grape juice, distributed over the country. Highest measured concentrations (As: 0.016; Cd: 0.010; Cr: 0.060; Cu: 1.28; Ni: 0.032; Pb: 0.016; Sb: 0.0040 and Zn: 1.44 mg L-1) comply with Brazilian maximal tolerance levels for inorganic contaminants (As: 0.5; Cd: 0.5; Cr: 0.1; Cu: 30; Ni: 3; Pb: 0.4

3. APERFEIÇOAMENTO E APLICAÇÕES DE UMA METODOLOGIA PARA ANÁLISE DE ESPECIAÇÃO DE ARSÊNIO POR ELETROFORESE CAPILAR COM DETECTOR DE ICPMS / IMPROVEMENTS AND APPLICATIONS OF A METHODOLOGY FOR THE SPECIATION ANALYSIS OF ARSENIC USING CAPILLARY ELECTROPHORESIS WITH ICPMS DETECTOR
Capillary electrophoresis (CE) is a well established separation technique for the study of elemental speciation, however, its low electroosmotic flow nL min(-1) restricts its application in many studies in which low detection limits are required. For this reason, the study of CE coupling (hyphenation) to more sensitive detectors is of great relevance. This w
