Nitrogen decontamination by molybdenum in high incidence area of esophageal cancer

Molybdenum (Mo) deficiency and nitrogen contamination have been proved to be relevant to the higher incidence of esophageal cancer. In order to reduce the amount of nitrate and nitrite in grains and vegetables, ammonium molybdate has been used as a trace-element fertilizer in Linxian County, a high risk area of esophageal cancer. This supplementation has significantly raised the yield and the Mo content of the crops. The nitrate and nitrite levels in crops and vegetables were reduced by 12-53 and 20-32% respectively. The amount of ascorbic acid in vegetables which can block the in vivo synthesis of nitroso compounds is increased by 10-70%.Taking the inhibitory effect of Mo on cancer into account, Mo supplement by using Mo fertilizer probably can serve as an effective chemoprevention measure against this disease in high risk areas.
