To study the effects of cell phone electromagnetic fields on germination and growth of mung bean.
Additionally, the changes in biomolecules and some enzyme activities were investigated to better understand the mechanism of action of mobile phones on early growth of plants.
Five sets of 50 seeds were divided into four exposure groups (exposed for 0.5, 1, 2, or 4 h) and one control group. Exposed seeds were allowed to germinate and grow for seven days before measurements were performed.

Exposure to cell phone electromagnetic fields affected the germination of mung beans depending upon the time of exposure: There was no change in seed germination when the seeds were exposed for less or equal two hours. However, exposure to an electromagnetic field for 4 h reduced the germination by 50%.
Additionally, cell phone exposure significantly reduced the seedling length and dry weight of mung bean after exposure for 0.5, 1, 2, and 4 h.
Furthermore, the contents of proteins and carbohydrates were reduced in electromagnetic field exposed plants. However, the enzyme activities of proteases, alpha-amylases, beta-amylases, polyphenol oxidases, and peroxidases were enhanced in mobile phone exposed radicles indicating their role in providing protection against electromagnetic field-induced stress.
The authors conclude that cell phone electromagnetic fields impair early growth of mung bean seedlings by inducing biochemical changes.
