 Author(s): PEREZ, D. V.; CAMPOS, R. C. de Size-exclusion chromatography is a powerful tool for distinguishing dissolved organic matter in relation to its molecular size. However, problems may arise in the choice of the most appropriate eluent... ... |
 Chemical speciation of hexavalent chromium in organic fertilizer by LC-ICP-MS and spectrophotometry. Author(s): SÁ, I. P.; BANHOS, S.; ANDRADE, M. S.; NHAMUE, P. F.; NOGUEIRA, A. R. de A. Normative Instruction n. 7 of 04/12/2016 of the Ministry of Agriculture, Livestock and Food Supply (MAPA) defines the maximum values of contaminants allowed in organic fertilizers and soil conditioner... ... |
 Author(s): FRESCHI, G. P. G.; NOGUEIRA, A. R. de A. Selenium is essential for the vital functions of the human and animal organism, such as growth, reproduction, prevention, and the protection of its muscular integrity. Although this dependence is well... ... |
 Author(s): SÁ, I. P. de; SOUZA, G. B. de; NOGUEIRA, A. R. de A. Brazilian and EU legislation establishes 2 mg kg?1 as the maximum limit of Cr(VI) in organic fertilizers. A procedure involving chromium speciation was developed. With this approach, the interference... ... |
 Author(s): MUNIZ, F. de L.; POLO, E.; CAMPOS, Z.; HERNÁNDEZ- RANGEL, S. M.; FARIAS, I. P.; HRBEK, T. Abstract: In our previous study we detected three Evolutionarily Significant Units and proposed that P. palpebrosus is a species complex. In the present study, we expanded our genomic sampling to 6,73... ... |
