Caracterização de minerais em farelo de arroz.
O objetivo do presente trabalho foi avaliar a variação da composição de minerais nas amostras de farelo de arroz fornecidas pela EMBRAPA, cultivadas em sistema irrigado e sequeiro e submetidas a diferentes processamentos e técnicas de estabilização, tendo em vista que o farelo pode ser utilizado como alimento e/ou ingrediente com propriedades nutricionais

Evidence of contamination by oil and oil products in the Santos-Sao Vicente estuary, Sao Paulo, Brazil
Different components of the mixed function oxidase (MFO) system and the levels of fluorescent aromatic compounds in bile (FACs) were measured in Cathorops spixii in order to assess the impact of polycyclic aromatic hydrocarbons (PAHs). Fish were sampled in an estuary (Santos/Sao Vicente) with a history of contamination by PAHs, mainly due to the presence of the industrial complex of Cubatao city and of another of low anthropogenic influence (Cananeia) on the Brazilian coast. FACs were higher in fish from the polluted site, and the PAH 5 and 6-ring metabolites were the most frequent - with 14% and 15%, respectively. Levels of the different components of the MFO system showed the same variation profile as the FACs for both estuaries. Therefore, the values found for somatic indexes and biomarkers with data of bile PAH metabolites indicate the presence of organic contaminants, especially in the area subject to the influence of the industrial complex on the Santos/Sao Vicente estuary.CAPES (Brazilian Agency for Science and Technology); Oceanographic Institute of Sao Paulo University; Laboratory of Ecotoxicology and Environmental Chemistry of the University of Algarve; CAPES-PDEE [BEX 2176/07-6]info:eu-repo/semantics/publishedVersio
