Ecotoxicity assessment of functionalized activated charcoal on the activity of the enzyme acetylcholinesterase and its effect in the presence of pesticides. Repositório Alice
VIANNA, M.; NOVOTNY, E. H.; SILVA, T. S.; RIBEIRO, B. R.; DITTZ, L. A..
The study of soil organic matter of the "Terras Pretas de Índios" showed an efficient compost model for improving the physical chemistry properties of the soil. The charred materials have the condensed aromatic structures but it does not provide carboxylic groups, that are important for its reactivity and its contribution to soil CEC. The objective of this study is to evaluate the ecotoxicity of functionalized charcoal compounds (humic acids like material - HALM) through its sub-lethal kinetic behaviour of the enzyme AChE even in the presence of pesticides. Activated charcoal was chemically oxidized using sodium hypochlorite. Brains of rats were used for ecotoxicity assay. The IC (half maximal inhibitory concentration) for AChE was 65 mg L-1 of HALM. The...

When enough should be enough: improving the use of current agricultural lands could meet production demands and spare natural habitats in Brazil. Repositório Alice
STRASSBURG, B. B. N.; LATAWIEC, A. E.; BARIONI, L. G.; NOBRE, C. A.; PORFIRIO-DA-SILVA, V.; VALENTIM, J. F.; VIANNA, M.; ASSAD, E. D..
Providing food and other products to a growing human population while safeguarding natural ecosystems and the provision of their services is a significant scientific, social and political challenge. With food demand likely to double over the next four decades, anthropization is already driving climate change and is the principal force behind species extinction, among other environmental impacts. The sustainable intensification of production on current agricultural lands has been suggested as a key solution to the competition for land between agriculture and natural ecosystems. However, few investigations have shown the extent to which these lands can meet projected demands while considering biophysical constraints. Here we investigate the improved use of...
