Controlling Arsenic Accumulation in Rice Grain under Nanomaterials-Assisted Optimal Greenhouse Set-Up

Rice is being increasingly exposed to inorganic arsenic and this affects half of the world population because they are rice consumers. In study, pot experiments were carried out investigate effect two dose-dependent nanomaterials (silica graphene) treatment on varied levels (2, 7 12 mg/kg). The results showed that both affected significantly with 1 mg/mL nanomaterial. Arsenic adversely plant height, tillering, number grains, grain weight when high concentrations applied at mg/kg, could not withstand it died before 75 days even in presence graphene. Based inductively coupled plasma mass spectrometry analysis, silica nanoparticles highest inhibition total accumulation as 93% (control plant), 84% (2 mg/kg), 67% (7 mg/kg) 35 % (12 whereas graphene lower percentages. This outcome confirms prevent uptake, translocate from root grains able offer a promising way reduce consumer health risk.
