    The fungus Aspergillus flavus was exposed to the north pole of the magnetic field and then compared its effect with the control treatment (without the magnetic field energy). The substrates used for the growth of A. flavus  (corn, wheat, rice and wheat flour) were obtained from the local market and sterilized by autoclaving. A  static magnetic field of 100 gauss was subjected to the A. flavus for (7, 14

          Phaseolus vulgaris seeds were surface sterilized using ethanol 90%, soaked in sterile distilled water for 60min, then soaked in copper and silver nanoparticles at different concentrations (25, 50 or 100mg/l) for 15 and 30min. The effect of nanoparticles on the plant physiological characteristics in vivo was studied.

One of the major environmental problems is the pollution of water by heavy metals. Using the biological treatment  is an effective way to reduce heavy concentration because it's environmental friendly,
