AbstractSamples from disposal water soils and plants were collected from eight locations along Tigris river banks during October (2010) at Mosul-city . These locations included eight small farms irrigated from disposal water. The study was aimed to access the extent of water pollution with some heavy metals (Arsenic and Cadmium), that used for irrigation. Chemical and physical analysis were carried out to water soil and plant samples including Arsenic and Cadmium. Results indicated that the highest Arsenic concentration was found in Albusyif disposal (South-West of Mosul). These results in accumulation of Arsenic in soil and plants which are irrigated from this disposal, while the lowest concentrations of this element was found in Al-Rashydia farm which irrigated from the river. However, for Cadmium it was found that Al-Danadan and Al-Khousar disposals posses the highest concentrations of this metal followed by 17-Tamoze disposal. This causes an increasing accumulation of Cadmium in soils and plants from the farms irrigated by this disposals. The lowest concentrations of Cadmium however was found in Al-Rasheydia farm which irrigated from the river.
