The titanium dioxide nanoparticles (NPs) have been applied to biomedical, pharmaceutical, and food additive fields. However, the effect on health and the environment are conf licting; thus, it has been reviewing several times. In this context, establishing standard robust protocols for detecting cytotoxicity and genotoxicity of nanomaterials became essential for nanotechnology development. The cell type and the intrinsic characteristics of titanium dioxide NPs can inf luence nanotoxicity. In this work, the cyto- and genotoxicity effects of standard reference material titanium dioxide NPs in primary bovine fibroblasts and immortalized Chinese hamster ovary epithelial (CHO) cells were determined and compared for the first time. Titanium dioxide NPs exposure revealed no cytotoxicity for primary bovine fibroblasts, while only higher concentrations tested (10 ?g/ml) induce genotoxic effects in this cell model. In contrast, the lower concentrations of the titanium dioxide NPs cause the cyto- and genotoxic effects in CHO cells. Therefore, our finding indicates that the CHO line was more sensitive toward the effects of titanium dioxide NPs than the primary bovine fibroblast, which should be valuable for their environmental risk assessment. |

The objective of this work was to analyze the effect of the integrated soybean system with sorghum and brachiaria on the levels of organic carbon, total N and mineral N in the soil. Super short cycle soybean BRS 7580 was planted, and subsequently, forage sorghum BRS 655 and BRS Piatã brachiaria were planted between the lines of the soybean. The levels of organic carbon, total nitrogen, ammonium, nitrate and mineral nitrogen/total nitrogen ratio were evaluated. The soil under Cerrado showed higher levels of organic carbon at all depths. There were no significant differences between treatments and the Cerrado for total nitrogen content in the deepest layers of the soil. All treatments showed a stratified distribution for the ammonium content, with higher values in the more superficial layers, decreasing in the deeper layers. Nitrate was not detected in the soil under Cerrado. Integrated crop treatments showed higher nitrate values than singles systems. In general, nitrate values were higher in the more superficial layers, with a significant decrease in the intermediate layers, increasing again in the 40-60 cm layer. The mineral nitrogen/total nitrogen ratio treatments with single or intercropped soybean maintained the same nitrate results pattern. |
