“…These analytes present a challenge no matter what chromatographic technique is used, requiring derivitisation to confer volatility for GC analysis or fluorescence or UV-absorbing properties for HPLC or CE analysis. Previously, these herbicides have been determined by CE-UV (ID) in their underivatised form but the relatively high LODs are likely to prohibit its application to real samples [55]. In this work, Goodwin et al explored CE coupled with MS.…”

The application of CE to the analysis of additives and organic contaminants in food since 2001 has been reviewed. Additives included in the review are dyes, preservatives, antioxidants and sweeteners. Organic contaminants included in the review are pesticides, antibiotics and those produced during processing or cooking food. The review highlights the strategies and approaches adopted in making CE suitable for the determination of analytes at residue level and in complicated matrices.

“…Capillary electrophoresis (Corbera et al, 2005), as an important separation technique due to its high resolving power and speed, was also reported for glyphosate anaysis. Some (Khrolenko & Wieczorek, 2005) used p-toluenesulfonyl chloride for derivatization prioe to CE separation, others (Cikalo et al, 1996) incorporates ribonucleotides into the background electrolyte to realize the indirect photometric detection. Chang (Chang & Liao, 2002) employed fluorescein as the buffer fluorophore and an argon-ion laser to induce the fluorescence background for detection of the glyphosate, AMPA, glufosinate and MPPA.…”

“…Os valores de suas constantes de ionização foram elucidados (Amarante Junior et al, 2002). Cikalo et al, (1996), consideram um comportamento zwinteriônico do glifosato quando descrevem sua dissociação. Neste caso, nas primeiras dissociações, o glifosato perderia os hidrogênios ligados a oxigênio, e apenas na última dissociação aquele ligado ao nitrogênio.…”

Efeitos de pesticidas sobre a fragilidade osmótica de eritrócitos – Uma breve revisão

et al. 2009

ResumoApesar da sua aplicação em outros setores, a agricultura tem sido a maior fonte de contaminação ambiental por praguicidas. Alguns praguicidas e seus metabólitos têm sido encontrados como poluentes no fundo e superfície de águas, no solo, e na atmosfera e são prováveis responsáveis pela perda da biodiversidade e a deterioração de hábitats naturais. Dentre os herbicidas, o Roundup® (Brasil) é o mais comum. Estudos recentes têm demonstrado que o glifosato, o pesticida mais utilizado na agricultura e considerado de baixo risco pelo EPA-US gera fragilidade osmótica de eritrócitos humanos e de ratos dentro das concentrações indicadas pelos fabricantes. As características da intoxicação por esse praguicida podem ser explicadas pela hipóxia causada pela hemólise dos eritrócitos. Os pesticidas podem estar associados com a aquisição de demências, com o aumento da população de idosos no país, o contato tempo-dependente dos indivíduos com substâncias nocivas aumentam e putativamente, o aumento de demências provocadas por fatores exógenos tende a aumentar também, desse modo a contaminação do ambiente por pesticidas e as doenças assim derivadas devem ser consideradas como um problema de saúde publica. Unitermos: praguicidas, membrana, fragilidade osmótica AbstractEffects of pesticides on the osmotic fragility of erythrocytes -A brief review. Despite their applications in other fields, agriculture is the main source of environmental contamination by pesticides. Pesticides and their metabolites have been found in the oceans, soil and atmosphere, and are probably responsible for the loss of biodiversity and deterioration of the natural environment. Roundup® is the pesticide most used in Brazil. Recents studies have demonstrated that ghyphosate (the main ingredient of Roundup®), while considered to be of low risk, generates osmotic fragility at the concentrations recommended by the manufactures. The problems caused by this pesticide can be explained by hypoxia caused by hemolysis of erythrocytes. Such pesticides can be Revisão
