RESUMOForam mapeados os resultados de P&D gerados no âmbito da Rede Nordeste de Biotecnologia (RENORBIO) apropriados por patentes, marcas, cultivares, softwares, desenhos industriais e outros intangíveis da Propriedade Industrial. A Transferência de Tecnologia e de Propriedade Intelectual no âmbito da RENORBIO está contribuindo para a formação de recursos humanos capacitados em extensão tecnológica com experiência em mapeamento e avaliação tecnológica. Deste modo se tem a visão crítica da biotecnologia e do desenvolvimento de produtos de qualidade com potencial de transferência para o setor empresarial e a sociedade em geral. A metodologia consiste em utilização de ferramentas de coleta e processamento de dados, identificação de mecanismos de prospecção e de partilha dos produtos apropriados por todas as ICTs da RENORBIO. Como produto principal está a contribuição para acelerar o processo de desenvolvimento da região Nordeste, transformando os produtos da pesquisa desenvolvidos pelos pesquisadores da RENORBIO em extensão tecnológica.
In this work we report the occurrence of powerful mutagenic 3-nitrobenzanthrone (3-NBA), in addition to 18 polycyclic aromatic hydrocarbons (PAHs), 6 oxygenated PAHs and 27 nitrated PAHs in polychaete worms. Benzanthrone (BA), another important mutagenic polycyclic aromatic compound (PAC) also was detected in the samples. Polychaete annelids have great ecological relevance, being widely distributed in different environmental conditions, from intertidal zones up to seven thousand feet deep areas. They are abundantly found in both contaminated and uncontaminated areas and, therefore, used as indicators of the pollution status of a given area. As we know, so far, most of these PACs has not been previously reported in living organisms before. The 3-NBA concentrations determined in this study were within 0.11–5.18 µg g−1. Other relevant PACs such as PAHs, quinones and nitro-PAHs were found in maximum concentrations at 0.013 µg g−1 (coronene) to 11.1 µg g−1 (benzo[k]fluoranthene), 0.823 µg g−1 (9,10-phenenthrenequinone) to 12.1 µg g−1 (1,4-benzoquinone) and 0.434 (1-nitronaphthalene) µg g−1 to 19.2 µg g−1 (6-nitrobenzo[a]pyrene), respectively. Principal component analysis (PCA), ternary correlations and diagnostic ratios were employed in order to propose probable sources for PACs. Although statistical analysis preliminarily has indicated both pyrogenic and petrogenic contributions, petrogenic sources were predominant reflecting the impacts of petroleum exploration and intensive traffic of boats in the study area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
