Magnetic environmental pollution: experimental simulation of engineered magnetic nanoparticles impact on Zea Mays vegetal embryos

摘要

The engineered nanoparticles release into the environment raises important ecological worldwide problems. To evaluate the effects of the magnetic nanoparticles on Zea mays vegetal embryos, we have accomplished experimental studies focused on the cell proliferation in the root tips tissue during the seeds germination under the influence of magnetic nanoparticles (MNPs) coated with different layers. Mitotic division process appears to be stimulated than controls and chromosomal aberrations occurred under MNPs presence. The experimental results have been comparatively analysed by means a statistically soft in order to obtain mathematical models to describe the MNPs influence on mitotic index and aberrations index.
