Implementação de metodologías de especiação nos laboratórios dosc grupos de pesquisa em espectrometria atômica e de massa e de pesquisas em cromatográfica e espectrometria atômica do departamento de química da UFSC:especiação de arsênio em óleo de peixe
Descrição: O presente projeto de pesquisa visa, através do estabelecimento de cooperação entre pesquisadores do Departamento de Química da UFSC e de um pesquisador da Universidade de Aberdeen (Escócia), viabilizar a implantação de um nova linha de pesquisa no DQ/UFSC, envolvendo a análise de especiação. Os procedimentos de especiação devem ser conduzidos por meio do acoplamento entre a cromatografia líquida de alta eficiência (HPLC) e a espectrometria de massa com plasma indutivamente acoplado (ICP-MS), permitindo o funcionamento conjunto do sistema de separação com um detector de alta sensibilidade, e a quantificação em níveis traço de espécies de As e Hg. As amostras serão oriundas de peixes e pescados brasileiros e de outros países da América do Sul, com particular enfoque na análise de amostras de óleo de peixe, comercializadas como fontes de ácidos graxos do tipo ômega-3 e ômega-6. O processo investigativo visa ainda, com maior especificidade, investigar a presença de arsenolipídeos nas amostras supracitadas, considerando a quantidade limitada de informações acerca da presença destes compostos nas amostras de peixes e derivados e a ausência de metodologias bem estabelecidas para a separação e detecção destes compostos, de alta toxicidade, em amostras oleosas. O Prof. Jörg Feldmann, da Universidade de Aberdeen, será convidado para integrar a equipe como Pesquisador Visitante Especial (PVE). O Prof. Feldmann é reconhecido internacionalmente como um dos pesquisadores de maior destaque na área de especiação química, com uma vasta gama de publicações sobre o assunto e colaborações estabelecidas com pesquisadores de diversos países. Atualmente, coordena o grupo TESLA (Trace Element Speciation Laboratory Aberdeen), na Escócia. A condução desta proposta deverá consolidar o vínculo com a instituição no exterior, permitindo o intercâmbio de estudantes e a condução conjunta de projetos de pesquisa. Diversos alunos de graduação e pós-graduação estarão diretamente envolvidos na condução dos experimentos, o que deverá originar trabalhos de conclusão de curso, dissertações e teses, além de publicações em periódicos de alto impacto..

Desenvolvimento de métodos rápidos e confiáveis para determinação de selênio em solos, sedimentos e materiais biológicos usando espectrometria de absorção atômica de alta resolução com fonte contínua e amostragem direta de sólidos em forno de grafite
Descrição: Atualmente pode-se afirmar que o selênio é o ?novo? oligoelemento por excelência. O selênio, diferentemente dos outros metais, é um elemento essencial à saúde humana. Atuando como a vitamina E ele protege as células do organismo contra danos oxidativos, especialmente retardando a oxidação do colesterol, catalisa as reações do mecanismo intermediário, bem como apresenta ação inibidora do efeito tóxico de metais pesados como As, Cd, Hg e Sn. O selênio é o elemento do qual a dose indispensável e que a resulta tóxica estão mais próximas, sendo uma dez vezes maior que a outra. A ingestão diária recomendada para adultos é de 55-70 μg; a ingestão de mais de 400 μg pode provocar efeitos tóxicos (selenoses). Há evidências de que o selênio está relacionado com a descoloração da pele e alguns problemas psicológicos e gastrointestinais. Existem estudos que indicam que em regiões onde há carência de selênio no solo, aparecem cardiopartias e alguns tipos de câncer. Em algumas zonas, sua presença no pasto, que o capta do solo, faz com que seja nocivo ao gado. Valores de concentrações acima de 400-700 μg por dia são consideradas tóxicas mesmo na forma orgânica. Os compostos de metilselênio são análogos aos do enxofre e apresentam uma função importante no ciclo biogeoquímico global do elemento. O selênio pode ser encontrado no solo e rochas, acabando por se acumular nas plantas, e é desta forma introduzido na cadeia alimentar. O selênio está presente na maioria dos alimentos, sendo que podemos encontrar boas fontes deste elemento nos frutos secos (especialmente na castanha do Pará), peixe, marisco, vísceras (rins ou fígado) e nas carnes. Os cereais, verduras e outros alimentos vegetais também contêm selênio, contudo, o seu teor varia de acordo com o tipo de solo a partir do qual se desenvolvem. O valores de ingestão de 34 g/dia de selênio para adultos, recomendados pela ANVISA (Agência Nacional de Vigilância Sanitária, Consulta Pública no. 80, de 13/12/2004.

Desenvolvimento de métodos para determinação dos halogênios F, Cl, Br e I em amostras biológicas, ambientais, industriais e de combustíveis usando espectrometria de absorção molecular de alta resolução com fonte contínua e forno de grafite.
Descrição: O objetivo da proposta foi de retomar a investigação da espectrometria de absorção molecular de alta resolução com fonte contínua (HR-CS MAS) como uma técnica analítica para a determinação dos halogênios em uma grande variedade de matrizes, utilizando um forno de grafite (GF) para a vaporização da amostra. No início, foi investigada a determinação de iodo utilizando HR-CS GF MAS. Os espectros de absorção de várias moléculas diatômicas foram estudados com o objetivo de encontrar um método analítico simples, sensível e de confiança para a determinação de iodo. Entre eles, o mono-iodeto de bário (BaI), para o qual as faixas de absorção estão entre 538 nm e 560 nm, foi o único que pôde ser usada analiticamente. A linha a mais forte do BaI, em 538.308 nm, foi avaliada sistematicamente para seu uso analítico na determinação do iodo. A maior parte da nossa pesquisa foi focada na determinação de flúor, utilizando inicialmente a molécula de fluoreto de gállio (GaF). Diferentes modificadores foram investigados para aumentar a robustez do método com o objetivo de utilizar padrões aquosos para calibração e finalmente aplicados na determinação de flúor em água potável e mineral. O mesmo método foi aplicado para a determinação de flúor em creme dental utilizando amostragem de suspensão e calibração com padrões aquosos. Os resultados foram comparados com os obtidos com cromatografia de gás e detector de espectrometria de massa e com eletrodo sensível para íons fluoreto. Outra molécula que foi investigada foi o fluoreto de cálcio (CaF) que foi usada para a determinação de flúor em chá e em saliva. A desvantagem de CaF, comparado com o GaF é a menor sensibilidade; as vantagens são um problema muito menor com o branco e um método muito mais simples, pois o cálcio funciona como formador da molécula e também como modificador químico. Durante o período de novembro de 2009 até novembro de 2011 foram publicados cinco artigos sobre a determinação de halogênios utilizando HR-CS GF MAS e.
