Abstract :
Introduction: Two areas suspected of Arsenic contamination regarding water and soil have been the subject of this investigation regarding raw milk The two selected areas are located at north west and south west of Qazvin province. Totally, 90 samples of water, soil and raw milk were collected during winter and summer. Materials and Methods: The samples were prepared and applied to Atomic absorption spectroscopy equipped with graphite furnace and the elements were quantified. Results: The results indicated that 86.6% of the samples were contaminated with Arsenic as compared to the standard limits for this element. The concentrations of Arsenic were 0.011-0.245, 7.662-29.89 and 0.0138-0.102 ppm for water, soil and milk samples respectively. Conclusion: This study has confirmed high concentrations of Arsenic in water and soil for the examined areas. The Arsenic contamination of milk might also be due to geographical location and area.
