Abstract :

Introduction: Regarding to the ground water pollution by Arsenic (As) in Ghorveh and Bijar field,contamination levels have been analyzed in irrigated plants (potato and carrot samples).Materials and Methods: Analyzes method have been by atomic absorption spectroscopy. Twentyfour potato samples (of the 12 potato plots) and 4 carrot samples (of the 2 carrot plots) picked up andAs contents were measured in skin and yield tissue separately. In potato of total 24 samples, 11samples had less than 10 μg As/kg, 9 samples had to10- 20 and 4 samples had As in the range of 20-25 μg As/kg.Skin-related Arsenic was higher than it in yield tissue. Of total skin samples: 17 samples had less than50 μg As/kg, 5 samples had As in the range of 50 t0 100 and the last 2 samples had As in the range of200-300 μg As/kg.All carrot samples showed As content less than 5 μg As/kg.Result and Discussion: (As) was high is some samples in skin of potato regarding to less transfer rateto eatable section, quantity will less with separate skin. In carrot, high quantity Arsenic ion is absorbedby roots because it has vast roots and transport in skin and
