In the environmental science and engineering community, nanohydroxyapatite (nHAp) has been widely applied for the remediation of contaminated soil and purification of wastewaters polluted with heavy metals for its strong ability to fix these contaminants. Based on this process, the aim of the present study was to evaluate the impact of nHAp in sorption/desorption of Cu, Zn, Fe and Mn in microcosm experiments, considering different environmental conditions and investigating the effects of pH, contact time and influence of natural organic matter and contamination with Cu and Zn. Due to its relevance as a regional water supply source, the environmental scenario of Juturnaíba reservoir (Rio de Janeiro State, Brazil) was chosen as basis for the microcosm experiments. It was observed that nHAp had an effect on Zn and Cu behavior, acting as a captor and promoting the reduction of their dissolved concentration in the water treatment sludge after water contamination with these metals. However, this behavior was modified by the addition of humic acid and acid to the microcosm system. On the other hand, the behavior of Fe and Mn was impacted by these nanoparticles in an opposite way. |

Varias estrategias de manejos tem sido adotadas para o controle da podridao radicular em mandioca para reduzir as perdas. Dentre as praticas adotadas, a rotacao de culturas com leguminosas e gramineas foi utilizada visando desde o controle da doenca ate as melhorias das qualidades fisicas e quimicas do solo, no Estado do Amazonas (Brasil). |
